To convert the fraction 3/16 to a decimal using long division, follow these steps:

1. Start by dividing the numerator (3) by the denominator (16) and place the decimal point above the division bar: 0.
- 3 ÷ 16 = 0.

2. Multiply the divisor (16) by the quotient digit (0), and subtract the result from the numerator (3):
- 3 - 0 × 16 = 3.

3. Bring down the next digit from the dividend (0) after the subtraction:

0._____
16 │ 3.00

4. Since the result of subtraction (3) is smaller than the divisor (16), add a zero after the decimal point in the quotient:

0.0_____
16 │ 3.00

5. Multiply the divisor (16) by the quotient digit (0), and subtract the result from the new dividend (30):
- 30 - 0 × 16 = 30.

6. Bring down the next digit from the dividend (0) after the subtraction:

0.00_____
16 │ 3.00

7. In this case, 30 is still smaller than 16, so add another zero to the quotient:

0.00_____
16 │ 3.00

8. Multiply the divisor (16) by the quotient digit (0), and subtract the result from the new dividend (300):
- 300 - 0 × 16 = 300.

9. Bring down the next digit from the dividend (0) after the subtraction:

0.003_____
16 │ 3.00

10. Now, 300 is larger than the divisor (16), so divide 300 by 16 to obtain a quotient, and place the result above the current division bar:

0.0037_____
16 │ 3.00

11. Multiply the divisor (16) by the quotient digit (3), and subtract the result from the new dividend (300):
- 300 - 3 × 16 = 252.

12. Bring down the next digit from the dividend (7) after the subtraction:

0.00375_____
16 │ 3.00

13. Divide 252 by 16 to obtain a new quotient digit (15), and place it above the current division bar:

0.00375_____
16 │ 3.001

14. Multiply the divisor (16) by the new quotient digit (15), and subtract the result from the new dividend (252):
- 252 - 15 × 16 = 12.

15. As there is no more dividend to bring down after the subtraction, the long division process ends here.

Therefore, 3/16 as a decimal is approximately 0.1875.
Use long division to convert 3 4/5 to a decimal.
To convert the mixed number 3 4/5 to a decimal using long division, follow these steps:

1. Convert the mixed number to an improper fraction:
- Multiply the whole number (3) by the denominator of the fraction (5): 3 × 5 = 15.
- Add the result to the numerator (4): 15 + 4 = 19.
- Write the sum as the new numerator over the denominator: 19/5.

2. Start by dividing the new numerator (19) by the denominator (5) and place the decimal point above the division bar: 3.
- 19 ÷ 5 = 3.

3. Multiply the divisor (5) by the quotient digit (3), and subtract the result from the numerator (19):
- 19 - 3 × 5 = 19 - 15 = 4.

4. Bring down the next digit from the dividend (0) after the subtraction:

3._____
5 │ 19.00

5. Since the result of subtraction (4) is smaller than the divisor (5), add a zero after the decimal point in the quotient:

3.0_____
5 │ 19.00

6. Multiply the divisor (5) by the quotient digit (3), and subtract the result from the new dividend (40):
- 40 - 3 × 5 = 40 - 15 = 25.

7. Bring down the next digit from the dividend (0) after the subtraction:

3.04_____
5 │ 19.00

8. Divide 25 by 5 to obtain a new quotient digit (5), and place it above the current division bar:

3.045_____
5 │ 19.00

9. Multiply the divisor (5) by the new quotient digit (5), and subtract the result from the new dividend (25):
- 25 - 5 × 5 = 25 - 25 = 0.

10. As there is no more dividend to bring down after the subtraction, the long division process ends here.

Therefore, 3 4/5 as a decimal is exactly 3.8.
