Solution - Long subtraction
Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | ones | . | tenths | hundredths | thousandths | ten thousandths |
| 4 | . | 8 | 9 | 2 | 2 | |
| - | 4 | . | 5 | 1 | 6 | 7 |
| . |
2. Subtract the numbers using long subtraction method
Because the upper digit (2) in the ten thousandths column is too small to get a positive difference, borrow 1 from the digit (2) in the next number place which becomes (1) and get (12).

| 1 | 12 | |||||
| 4 | . | 8 | 9 | 2 | 2 | |
| - | 4 | . | 5 | 1 | 6 | 7 |

Subtract the numbers in the ten thousandths column from the top number:
12-7=5

Because the upper digit (1) in the thousandths column is too small to get a positive difference, borrow 1 from the digit (9) in the next number place which becomes (8) and get (11).

Subtract the numbers in the ones column from the top number:
4-4=0
