Step-by-Step Place Value Division Strategies
The concept of Use of Place Value to Divide is essential for mastering basic division skills in mathematics. Understanding how to break numbers into place value parts makes division easier, especially for large numbers. This skill is vital for students in classes 3 to 5, helping them excel in school exams and building confidence for daily problem-solving.
What is Place Value?
Place value is the value given to a digit based on its position in a number. Each digit has a place (ones, tens, hundreds, thousands, etc.), and the digit’s value depends on its place. For example, in the number 3824:
| Thousands | Hundreds | Tens | Ones |
|---|---|---|---|
| 3 | 8 | 2 | 4 |
| 3 × 1000 = 3000 | 8 × 100 = 800 | 2 × 10 = 20 | 4 × 1 = 4 |
So, 3824 = 3000 + 800 + 20 + 4.
This method of breaking a number into parts helps in addition, subtraction, multiplication, and especially division.
Why Use Place Value in Division?
Using place value for division simplifies the process, making it easier to divide big numbers without confusion. By dividing each part (thousands, hundreds, tens, ones) separately and then combining the results, students can avoid mistakes and understand what each digit means. This method connects division with mental math, helps visualize the process with place value charts or blocks, and encourages logical thinking.
- Breaks difficult problems into simple steps.
- Makes division of large numbers less overwhelming.
- Builds number sense and confidence.
- Helpful for both written and mental calculations.
- Reduces common division mistakes.
Step-by-Step Place Value Division Strategies
Let’s learn how to use place value to divide with two popular strategies: by partitioning and with place value charts/blocks.
1. Partitioning (Breaking Up Numbers)
- Write the number in expanded/partitioned form based on place values.
- Divide each part/place value by the divisor.
- Add up all the answers to get the final quotient.
Example: 4200 ÷ 6
- Expanded form: 4000 + 200
- Divide each:
- 4000 ÷ 6 = 666 (remainder 4)
- 200 ÷ 6 = 33 (remainder 2)
- Step by step (showing regrouping and combining as needed):
| Step | Calculation | Quotient | Remainder |
|---|---|---|---|
| 1 | 4000 ÷ 6 | 666 | 4 |
| 2 | (4 × 1000 left: 4 hundreds = 400, +200 = 600) 600 ÷ 6 | 100 | 0 |
| Total | 666 + 100 | 766 | Remainder from ones/tens if any |
2. Using Place Value Charts or Blocks
- Draw a place value chart for thousands, hundreds, tens, ones.
- Put the number’s digits in the chart.
- Divide starting with the highest place (e.g., thousands). If cannot divide evenly, regroup extras to the next place.
- Repeat till you reach the ones place.
Example: 4800 ÷ 6
- Thousands: 4 (means 4000). 4000 ÷ 6 = 666, remainder 4 × 1000 = 4000 – (666 × 6 × 1,000) = leftover 4000 for hundreds/tens.
- But since 4 < 6, move all 4000 into hundreds = 40 hundreds.
- Now, hundreds: 8 (original) + 40 (from thousands) = 48.
- 48 hundreds ÷ 6 = 8 hundreds.
- Remainder: none. Continue with tens and ones as needed.
Visualizing with blocks: Separate the total number using blocks or counters (place value disks), then share equally into 6 equal groups place by place.
Worked Examples
Example 1: 4200 ÷ 6 using place value
- Break 4200 → 4000 + 200
- Divide thousands: 4000 ÷ 6 = 666 (remainder 4)
- Remainder 4 thousands = 4000 added to hundreds (if possible) or converted to hundreds/tens
- Combine with existing 200: 400 (from leftover thousands) + 200 = 600
- Divide hundreds: 600 ÷ 6 = 100
- Add up: 666 + 100 = 766
The quotient is 700 (if sticking to simple chunking) with a remainder, or follow long division style for exact quotient 700.
Or, using standard division:
4200 ÷ 6 = 700
Example 2: 4800 ÷ 6 using place value blocks
- 4 thousands = 4000
- 8 hundreds = 800
- Step 1: 4000 ÷ 6 = 666 × 6 = 3996 (remainder 4)
- Leftover: 4 hundreds + 8 hundreds = 12 hundreds = 1200
- 1200 ÷ 6 = 200
- Total quotient: 666 (thousands part) + 200 (hundreds part) = 800
The answer is 800. (Check: 800 × 6 = 4800)
Practice Problems
- Divide 3500 by 5 using place value partitioning.
- Find the quotient and remainder for 738 ÷ 6 using place value methods.
- Use a place value chart to solve 2600 ÷ 4.

Common Mistakes to Avoid
- Confusing the digit with its place value (e.g., 3 in 348 is not just 3, it's 300).
- Forgetting to regroup the remainder when a place value isn't fully divisible.
- Adding quotients without properly aligning the place values.
- Leaving out the remainder in the answer.
- Not double-checking by multiplying the quotient back with the divisor.
Real-World Applications
Using place value to divide is handy whenever you need to share or distribute large quantities. For example:
- Dividing money equally among friends.
- Sharing sweets, pencils, or books in a classroom.
- Packing items in boxes of fixed size for shipping.
- Calculating bills or splitting costs in real life.

Visual aids are extremely helpful when understanding place value division. Place value charts and blocks are effective tools for visualizing the process of breaking down numbers and performing division step-by-step. They cater to visual learners and aid comprehension of the place value method for division.
9. How does the place value division strategy relate to algebraic division concepts?
The place value division strategy provides a foundational understanding that relates to algebraic division. Both methods involve breaking down expressions (numbers or polynomials) into parts to simplify the division process. Understanding place value helps build a stronger understanding of division in algebra.
10. What happens when dividing decimals using place value methods?
When dividing decimals using place value methods, you need to consider the decimal point's position. Align the decimal points before dividing and continue the division process as usual, following the principles of place value. The decimal point in the quotient will be aligned vertically with the decimal point in the dividend.
