Explanation:
We are given four division problems, and each one asks us to rewrite the division as repeated subtraction. That means we subtract the divisor (the number we’re dividing by) repeatedly from the dividend (the number we’re dividing) until we reach zero. The number of times we subtract is the quotient.
Let’s solve each one step by step.

Problem 1: 18 ÷ 3 = □
We start with 18 and subtract 3 repeatedly:
- 18 − 3 = 15
- 15 − 3 = 12
- 12 − 3 = 9
- 9 − 3 = 6
- 6 − 3 = 3
- 3 − 3 = 0
We subtracted 3 a total of
6 times, so 18 ÷ 3 =
6.

Problem 2: 12 ÷ 3 = □
Start with 12, subtract 3 repeatedly:
- 12 − 3 = 9
- 9 − 3 = 6
- 6 − 3 = 3
- 3 − 3 = 0
That’s
4 subtractions, so 12 ÷ 3 =
4.

Problem 3: 18 ÷ 6 = □
Start with 18, subtract 6:
- 18 − 6 = 12
- 12 − 6 = 6
- 6 − 6 = 0
That’s
3 subtractions, so 18 ÷ 6 =
3.

Problem 4: 48 ÷ 2 = □
Start with 48, subtract 2 repeatedly:
- 48 − 2 = 46
- 46 − 2 = 44
- 44 − 2 = 42
- 42 − 2 = 40
- 40 − 2 = 38
- 38 − 2 = 36
- 36 − 2 = 34
- 34 − 2 = 32
- 32 − 2 = 30
- 30 − 2 = 28
- 28 − 2 = 26
- 26 − 2 = 24
- 24 − 2 = 22
- 22 − 2 = 20
- 20 − 2 = 18
- 18 − 2 = 16
- 16 − 2 = 14
- 14 − 2 = 12
- 12 − 2 = 10
- 10 − 2 = 8
- 8 − 2 = 6
- 6 − 2 = 4
- 4 − 2 = 2
- 2 − 2 = 0
Count them: that’s
24 subtractions, so 48 ÷ 2 =
24.
(Alternatively, you can think: 48 ÷ 2 = 24 — since 2 × 24 = 48 — and verify the subtraction count matches.)
