1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 4 | 5 | 6 | 7 | 3 | |

2. Subtract the numbers using long subtraction method
Because the upper digit (3) in the ones column is too small to get a positive difference, borrow 1 from the digit (7) in the next number place which becomes (6) and get (13).
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 6 | 13 | ||||

Subtract the numbers in the ones column from the top number:
13-5=8
| Place value | ten thousands | thousands | hundreds | tens | ones |
