Division Problems (Long Division):
(g) 1341 ÷ 3
How many times does 3 go into 1? → 0
Into 13? → 4 times (4×3=12), remainder 1
Bring down 4 → 14
3 into 14 → 4 times (4×3=12), remainder 2
Bring down 1 → 21
3 into 21 → 7 times (7×3=21), remainder 0
Answer:
447
(h) 7304 ÷ 8
8 into 7 → 0
Into 73 → 9 times (9×8=72), remainder 1
Bring down 0 → 10
8 into 10 → 1 time (1×8=8), remainder 2
Bring down 4 → 24
8 into 24 → 3 times (3×8=24), remainder 0
Answer:
913
(i) 5474 ÷ 7
7 into 5 → 0
Into 54 → 7 times (7×7=49), remainder 5
Bring down 7 → 57
7 into 57 → 8 times (8×7=56), remainder 1
Bring down 4 → 14
7 into 14 → 2 times (2×7=14), remainder 0
Answer:
782
(j) 1547 ÷ 7
7 into 1 → 0
Into 15 → 2 times (2×7=14), remainder 1
Bring down 4 → 14
7 into 14 → 2 times (2×7=14), remainder 0
Bring down 7 → 7
7 into 7 → 1 time (1×7=7), remainder 0
Answer:
221
(k) 2490 ÷ 3
3 into 2 → 0
Into 24 → 8 times (8×3=24), remainder 0
Bring down 9 → 9
3 into 9 → 3 times (3×3=9), remainder 0
Bring down 0 → 0
3 into 0 → 0
Answer:
830
(l) 1620 ÷ 4
4 into 1 → 0
Into 16 → 4 times (4×4=16), remainder 0
Bring down 2 → 2
4 into 2 → 0, so we write 0 and bring down next digit → 20
4 into 20 → 5 times (5×4=20), remainder 0
Answer:
405
