1. $ 5 \overline{)843} $

We divide 843 by 5.

- Step 1: 5 goes into 8 once → $ 5 \times 1 = 5 $
- Subtract: $ 8 - 5 = 3 $
- Bring down 4 → 34
- Step 2: 5 goes into 34 six times → $ 5 \times 6 = 30 $
- Subtract: $ 34 - 30 = 4 $
- Bring down 3 → 43
- Step 3: 5 goes into 43 eight times → $ 5 \times 8 = 40 $
- Subtract: $ 43 - 40 = 3 $

So, $ 843 \div 5 = 168 $ remainder 3

✔ Answer: $ 168 R3 $

2. $ 3 \overline{)343} $

Divide 343 by 3.

- Step 1: 3 goes into 3 once → $ 3 \times 1 = 3 $
- Subtract: $ 3 - 3 = 0 $
- Bring down 4 → 4
- Step 2: 3 goes into 4 once → $ 3 \times 1 = 3 $
- Subtract: $ 4 - 3 = 1 $
- Bring down 3 → 13
- Step 3: 3 goes into 13 four times → $ 3 \times 4 = 12 $
- Subtract: $ 13 - 12 = 1 $

So, $ 343 \div 3 = 114 $ remainder 1

✔ Answer: $ 114 R1 $

3. $ 2 \overline{)734} $

Divide 734 by 2.

- Step 1: 2 goes into 7 three times → $ 2 \times 3 = 6 $
- Subtract: $ 7 - 6 = 1 $
- Bring down 3 → 13
- Step 2: 2 goes into 13 six times → $ 2 \times 6 = 12 $
- Subtract: $ 13 - 12 = 1 $
- Bring down 4 → 14
- Step 3: 2 goes into 14 seven times → $ 2 \times 7 = 14 $
- Subtract: $ 14 - 14 = 0 $

So, $ 734 \div 2 = 367 $ remainder 0

✔ Answer: $ 367 $

4. $ 4 \overline{)767} $

Divide 767 by 4.

- Step 1: 4 goes into 7 one time → $ 4 \times 1 = 4 $
- Subtract: $ 7 - 4 = 3 $
- Bring down 6 → 36
- Step 2: 4 goes into 36 nine times → $ 4 \times 9 = 36 $
- Subtract: $ 36 - 36 = 0 $
- Bring down 7 → 7
- Step 3: 4 goes into 7 one time → $ 4 \times 1 = 4 $
- Subtract: $ 7 - 4 = 3 $

So, $ 767 \div 4 = 191 $ remainder 3

✔ Answer: $ 191 R3 $

5. $ 3 \overline{)882} $

Divide 882 by 3.

- Step 1: 3 goes into 8 two times → $ 3 \times 2 = 6 $
- Subtract: $ 8 - 6 = 2 $
- Bring down 8 → 28
- Step 2: 3 goes into 28 nine times → $ 3 \times 9 = 27 $
- Subtract: $ 28 - 27 = 1 $
- Bring down 2 → 12
- Step 3: 3 goes into 12 four times → $ 3 \times 4 = 12 $
- Subtract: $ 12 - 12 = 0 $

So, $ 882 \div 3 = 294 $ remainder 0

✔ Answer: $ 294 $

6. $ 2 \overline{)157} $

Divide 157 by 2.

- Step 1: 2 goes into 1 zero times → bring down 5 → 15
- Step 2: 2 goes into 15 seven times → $ 2 \times 7 = 14 $
- Subtract: $ 15 - 14 = 1 $
- Bring down 7 → 17
- Step 3: 2 goes into 17 eight times → $ 2 \times 8 = 16 $
- Subtract: $ 17 - 16 = 1 $

So, $ 157 \div 2 = 78 $ remainder 1

✔ Answer: $ 78 R1 $

7. $ 8 \overline{)283} $

Divide 283 by 8.

- Step 1: 8 goes into 2 zero times → bring down 8 → 28
- Step 2: 8 goes into 28 three times → $ 8 \times 3 = 24 $
- Subtract: $ 28 - 24 = 4 $
- Bring down 3 → 43
- Step 3: 8 goes into 43 five times → $ 8 \times 5 = 40 $
- Subtract: $ 43 - 40 = 3 $

So, $ 283 \div 8 = 35 $ remainder 3

✔ Answer: $ 35 R3 $

8. $ 3 \overline{)448} $

Divide 448 by 3.

- Step 1: 3 goes into 4 one time → $ 3 \times 1 = 3 $
- Subtract: $ 4 - 3 = 1 $
- Bring down 4 → 14
- Step 2: 3 goes into 14 four times → $ 3 \times 4 = 12 $
- Subtract: $ 14 - 12 = 2 $
- Bring down 8 → 28
- Step 3: 3 goes into 28 nine times → $ 3 \times 9 = 27 $
- Subtract: $ 28 - 27 = 1 $

So, $ 448 \div 3 = 149 $ remainder 1

✔ Answer: $ 149 R1 $
