What Is Benchmark MA.4.NSO.2.4?

Students divide a whole number with up to four digits by a one-digit number using a method they can use reliably, such as partial quotients, place value models, or the relationship between multiplication and division.

Remainders are written as a fraction of the divisor. For example, 25 ÷ 4 is 6 with a remainder of 1, which is 614.

Official benchmarkDivide a whole number up to four digits by a one-digit whole number with procedural reliability. Represent remainders as fractional parts of the divisor.

On the FAST test: part of the Grade 4 reporting category Number Sense and Operations with Whole Numbers, which is about 31–37% of the test.

Worked Examples

Worked Example 1

Partial Quotients

846 ÷ 6
  1. 1Take out 100 groups of 6: 6 × 100 = 600. 846 − 600 = 246 left.
  2. 2Take out 40 groups of 6: 6 × 40 = 240. 246 − 240 = 6 left.
  3. 3Take out 1 group of 6: 6 × 1 = 6. Nothing is left.
  4. 4100 + 40 + 1 = 141
Answer: 141

Worked Example 2

A Remainder as a Fraction

1,253 ÷ 4
  1. 14 × 300 = 1,200, leaving 53.
  2. 24 × 13 = 52, leaving 1.
  3. 3300 + 13 = 313 with a remainder of 1.
  4. 4The remainder 1 out of the divisor 4 is 14.
Answer: 31314

Common Mistakes to Watch For

Leaving a remainder bigger than the divisor

Wrong:50 ÷ 6 = 7 R8

If the remainder is 6 or more, another group of 6 fits. 6 × 8 = 48, so 50 ÷ 6 = 8 R2, or 826.

Writing the remainder over the wrong number

Wrong:25 ÷ 4 = 6125

The remainder is a fraction of the divisor: 25 ÷ 4 = 614.

Helpful Math Tip

Check division with multiplication: quotient × divisor + remainder should equal the number you started with.
