Dividing Decimals by Whole Numbers

9.6 ÷ 4 uses the short division your child already knows, with one extra rule: the decimal point in the answer sits directly above the one in the question. This lesson locks that habit in.

Learn the 3-Step Method

1Set up short division.

Write the decimal under the bus stop; copy the point straight up into the answer line.

4)9.6

2Divide the whole part.

9 ÷ 4 = 2 remainder 1. Write 2; carry the 1 into the tenths.

2, carry 1

3Divide the decimal part.

The carried 1 makes 16 tenths. 16 ÷ 4 = 4 tenths. Answer: 2.4.

2.4
💡 Key IdeaThe point never moves: it sits in the answer directly above the point in the question.

Watch Out! Common Mistakes

Dropping the decimal point.
9.6 ÷ 4 = 24 ✕

Wrong! Copy the point straight up before you start: 2.4.

Ignoring the remainder.
9.6 ÷ 4 → 9 ÷ 4 = 2, 6 ÷ 4 = 1 → 2.1 ✕

Wrong! The remainder 1 from the ones must carry into the tenths: 16 tenths ÷ 4 = 4. Answer: 2.4.

Stopping too soon.
8.35 ÷ 5 = 1.6 ✕

Wrong! There are still hundredths to divide. Keep going: 1.67.

Quick summary

Frequently asked questions

How do you divide a decimal by a whole number?

Use short division (the bus stop method), writing the decimal point in the answer directly above the point in the question, and carry remainders as usual: 9.6 ÷ 4 = 2.4.

What happens to remainders when dividing decimals?

They carry into the next column exactly as in whole-number division — a remainder of 1 in the ones becomes 10 extra tenths.
