Divide :
`0.688 div 8`

Answer

To solve the problem of dividing 0.688 by 8, we can follow these steps:

### Step-by-Step Solution:

1. **Set up the division**: We need to divide 0.688 by 8. We can write this as \( 0.688 \div 8 \).

2. **Identify the decimal point**: Since 0.688 is a decimal number, we will place the decimal point in our answer directly above the decimal point in the dividend (0.688).

3. **Consider the first digit**: The first digit is 6. Since 6 is smaller than 8, we cannot divide it. So, we write 0 in the quotient and move to the next digit.

4. **Consider the first two digits (68)**: Now we look at the first two digits, which are 68. We need to find how many times 8 can fit into 68.
- 8 x 8 = 64 (this is the largest multiple of 8 that is less than 68).

5. **Subtract**: Now we subtract 64 from 68.
- \( 68 - 64 = 4 \).

6. **Bring down the next digit (8)**: Now we bring down the next digit, which is 8, making it 48.

7. **Divide 48 by 8**: Now we find how many times 8 fits into 48.
- 8 x 6 = 48.

8. **Subtract again**: Now we subtract 48 from 48.
- \( 48 - 48 = 0 \).

9. **Write the final answer**: Since we have finished dividing, we can now write the quotient. The quotient is 0.086.

### Final Answer:
\( 0.688 \div 8 = 0.086 \)
