1a. 19038 ÷ 2
We divide 19038 by 2.
- 2 goes into 1 → 0 (write 0, carry 1)
- 2 goes into 19 → 9 times (9×2=18), remainder 1
- Bring down 0 → 10
- 2 goes into 10 → 5 times (5×2=10), remainder 0
- Bring down 3 → 3
- 2 goes into 3 → 1 time (1×2=2), remainder 1
- Bring down 8 → 18
- 2 goes into 18 → 9 times (9×2=18), remainder 0
So:
19038 ÷ 2 = 9519
✔ Check: 9519 × 2 = 19038 → Correct.

1b. 90018 ÷ 2
Divide 90018 by 2.
- 2 into 9 → 4 (4×2=8), remainder 1
- Bring down 0 → 10
- 2 into 10 → 5, remainder 0
- Bring down 0 → 0
- 2 into 0 → 0
- Bring down 1 → 1
- 2 into 1 → 0, remainder 1
- Bring down 8 → 18
- 2 into 18 → 9
So:
90018 ÷ 2 = 45009
✔ Check: 45009 × 2 = 90018 → Correct.

1c. 31764 ÷ 6
Divide 31764 by 6.
- 6 into 3 → 0, so look at 31
- 6 into 31 → 5 (5×6=30), remainder 1
- Bring down 7 → 17
- 6 into 17 → 2 (2×6=12), remainder 5
- Bring down 6 → 56
- 6 into 56 → 9 (9×6=54), remainder 2
- Bring down 4 → 24
- 6 into 24 → 4 (4×6=24), remainder 0
So:
31764 ÷ 6 = 5294
✔ Check: 5294 × 6 = 31764 → Correct.

2a. 40508 ÷ 4
Divide 40508 by 4.
- 4 into 4 → 1
- 4 into 0 → 0
- 4 into 5 → 1 (1×4=4), remainder 1
- Bring down 0 → 10
- 4 into 10 → 2 (2×4=8), remainder 2
- Bring down 8 → 28
- 4 into 28 → 7
So:
40508 ÷ 4 = 10127
✔ Check: 10127 × 4 = 40508 → Correct.

2b. 86478 ÷ 3
Divide 86478 by 3.
- 3 into 8 → 2 (2×3=6), remainder 2
- Bring down 6 → 26
- 3 into 26 → 8 (8×3=24), remainder 2
- Bring down 4 → 24
- 3 into 24 → 8
- Bring down 7 → 7
- 3 into 7 → 2 (2×3=6), remainder 1
- Bring down 8 → 18
- 3 into 18 → 6
So:
86478 ÷ 3 = 28826
✔ Check: 28826 × 3 = 86478 → Correct.

2c. 99526 ÷ 7
Divide 99526 by 7.
- 7 into 9 → 1 (1×7=7), remainder 2
- Bring down 9 → 29
- 7 into 29 → 4 (4×7=28), remainder 1
- Bring down 5 → 15
- 7 into 15 → 2 (2×7=14), remainder 1
- Bring down 2 → 12
- 7 into 12 → 1 (1×7=7), remainder 5
- Bring down 6 → 56
- 7 into 56 → 8
So:
99526 ÷ 7 = 14218
✔ Check: 14218 × 7 = 99526 → Correct.
