📚 Dividing Decimals

The Move-the-Decimal Method

1
Make the divisor a whole number by moving its decimal point to the right.
8.4 ÷ 0.4 → move divisor 1 place right → 0.4 becomes 4
2
Move the dividend's decimal the same number of places.
8.4 also moves 1 place → 84
3
Divide as with whole numbers.
84 ÷ 4 = 21

Divide Decimal Integers (with Signs)

1
Divide the absolute values as normal decimal division.
6.4 ÷ 4 = 1.6  |  0.36 ÷ 4 = 0.09
2
Apply the sign rule: same signs → positive; different signs → negative.
−6.4 ÷ 4 = −1.6  |  6.4 ÷ −4 = −1.6  |  −6.4 ÷ −4 = 1.6

Quick Examples

3.6 ÷ 0.9
→ 36 ÷ 9
= 4
4.5 ÷ 1.5
→ 45 ÷ 15
= 3
7.2 ÷ 4
→ divide normally
= 1.8
