Step-by-step solution for: Dividing Decimals by Various Decimals with Various Sizes of ...
Let’s solve each division problem step by step. We’re dividing decimals, so we’ll move the decimal point in both the divisor and dividend to make the divisor a whole number — then divide as usual.
---
Problem 1: 0.58 ) 0.5568
Move decimal 2 places right in both:
→ 58 ) 55.68
Now divide 55.68 ÷ 58.
58 goes into 556 (first three digits) 9 times → 58 × 9 = 522
Subtract: 556 - 522 = 34
Bring down 8 → 348
58 goes into 348 exactly 6 times → 58 × 6 = 348
So answer is 0.96
Wait — let’s check: 0.58 × 0.96 = ?
0.58 × 0.96 = (58/100) × (96/100) = (58×96)/10000
58×96: 58×100=5800 minus 58×4=232 → 5800-232=5568 → 5568/10000 = 0.5568 ✔
✔ Answer: 0.96

Problem 2: 0.2 ) 0.12
Move decimal 1 place right:
→ 2 ) 1.2
1.2 ÷ 2 = 0.6
Check: 0.2 × 0.6 = 0.12 ✔
✔ Answer: 0.6
---
Problem 3: 0.7 ) 0.1995
Move decimal 1 place right:
→ 7 ) 1.995
Divide 1.995 ÷ 7
7 into 19 → 2 (7×2=14), remainder 5
Bring down 9 → 59
7 into 59 → 8 (7×8=56), remainder 3
Bring down 5 → 35
7 into 35 → 5
So: 0.285
Check: 0.7 × 0.285 = ?
0.7 × 0.285 = 7/10 × 285/1000 = (7×285)/10000
7×285: 7×200=1400, 7×80=560, 7×5=35 → 1400+560=1960+35=1995 → 1995/10000 = 0.1995 ✔
✔ Answer: 0.285
---
Problem 4: 1.5 ) 1.2
Move decimal 1 place right:
→ 15 ) 12.0
12.0 ÷ 15 = 0.8
Check: 1.5 × 0.8 = 1.2 ✔
✔ Answer: 0.8
---
Problem 5: 0.1 ) 0.0805
Move decimal 1 place right:
→ 1 ) 0.805
0.805 ÷ 1 = 0.805
Check: 0.1 × 0.805 = 0.0805 ✔
✔ Answer: 0.805
---
Problem 6: 0.6 ) 1.452
Move decimal 1 place right:
→ 6 ) 14.52
14.52 ÷ 6
6 into 14 → 2 (12), remainder 2
Bring down 5 → 25
6 into 25 → 4 (24), remainder 1
Bring down 2 → 12
6 into 12 → 2
So: 2.42
Check: 0.6 × 2.42 = ?
0.6 × 2.42 = 6/10 × 242/100 = (6×242)/1000
6×242: 6×200=1200, 6×40=240, 6×2=12 → 1200+240=1440+12=1452 → 1452/1000 = 1.452 ✔
✔ Answer: 2.42
---
Problem 7: 0.5 ) 0.05
Move decimal 1 place right:
→ 5 ) 0.5
0.5 ÷ 5 = 0.1
Check: 0.5 × 0.1 = 0.05 ✔
✔ Answer: 0.1
---
Problem 8: 3.64 ) 28.5376
Move decimal 2 places right:
→ 364 ) 2853.76

2853 - 2548 = 305
Bring down 7 → 3057
364 × 8 = 2912
3057 - 2912 = 145
Bring down 6 → 1456
364 × 4 = 1456
So: 7.84
Check: 3.64 × 7.84
First, 364 × 784 = ?
But easier: 3.64 × 7.84
Break it: 3.64 × 7 = 25.48
3.64 × 0.8 = 2.912
3.64 × 0.04 = 0.1456
Add: 25.48 + 2.912 = 28.392 + 0.1456 = 28.5376 ✔
✔ Answer: 7.84
---
Problem 9: 1.92 ) 1.152
Move decimal 2 places right:
→ 192 ) 115.2
115.2 ÷ 192
Since 192 > 115.2, answer < 1 → start with 0.
