Use long division to convert 316 to a decimal.

To convert 316 to a decimal using long division, divide 316 by 100, as there are two places after the decimal point:

```
3.16
----
100) 316
-300
----
16
```

The resulting decimal is 3.16.

To convert 316 to a decimal using long division, you can follow the below steps:

1. Divide the numerator (316) by the denominator (1) to get the quotient.

Quotient = 316 รท 1 = 316

2. Since the denominator is 1, the quotient is the same as the given number (316).

Therefore, 316 as a decimal is simply 316.

To convert a whole number into a decimal using long division, you can follow these steps:

1. Write down the number you want to convert (316) as the dividend.

2. Choose a divisor. In this case, we want to convert to a decimal, so we will use 1 as the initial divisor.

3. Divide the first digit of the dividend (3) by the divisor (1). Write the quotient above the line.

3
______
1 | 316

Quotient: 3

4. Multiply the quotient by the divisor (1) and write the product below the dividend.

3
______
1 | 316
- 3

...
...

5. Subtract the product from the first part of the dividend. Write the resulting value below the line.

3
______
1 | 316
- 3
16

6. Bring down the next digit from the dividend (6) next to the remainder.

3
______
1 | 316
- 3
16
6

7. Divide the new number (16) by the divisor (1).

3
______
1 | 316
- 3
16
---
16

Quotient: 16

8. Multiply the new quotient (16) by the divisor (1) and write the product below the dividend.

3
______
1 | 316
- 3
16
---
16
16

9. Subtract the product from the second part of the dividend. Write the resulting value below the line.

3
______
1 | 316
- 3
16
---
16
16
---
0

10. Since we have reached a remainder of 0, we can stop the division. The decimal representation of 316 is 316.0.

Therefore, the decimal representation of 316 is 316.0.
