Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 4 | 2 | 8 | 3 | 4 | |

2. Subtract the numbers using long subtraction method
Because the upper digit (4) in the ones column is too small to get a positive difference, borrow 1 from the digit (3) in the next number place which becomes (2) and get (14).
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 2 | 14 | ||||
| 4 | 2 | 8 | 3 | 4 | |

Subtract the numbers in the ones column from the top number:
14-6=8
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 2 | 14 | ||||
| 4 | 2 | 8 | 3 | 4 | |
| - | 6 | ||||
| 8 |
Write 2 in the tens place.
| Place value | ten thousands | thousands | hundreds | tens | ones |
