Solution - Long subtraction
2.7238
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 |
| 6 | . | 0 | 4 | 3 | 8 | |
| - | 3 | . | 3 | 2 | ||
| . |
Put zeros in the blank number places:
| Place value | ones | . | tenths | hundredths | thousandths | ten thousandths |
| 6 | . | 0 | 4 | 3 | 8 | |
| - | 3 | . | 3 | 2 | 0 | 0 |
| . |
2. Subtract the numbers using long subtraction method
Subtract the numbers in the ten thousandths column from the top number:
8-0=8
| Place value | ones | . | tenths | hundredths | thousandths | ten thousandths |
| 6 | . | 0 | 4 | 3 | 8 | |
| - | 3 | . | 3 | 2 | 0 | 0 |
| . | 8 |
Subtract the numbers in the thousandths column from the top number:
3-0=3
| Place value | ones | . | tenths | hundredths | thousandths | ten thousandths |
| 6 | . | 0 | 4 | 3 | 8 | |
| - | 3 | . | 3 | 2 | 0 | 0 |
| . | 3 | 8 |
Subtract the numbers in the hundredths column from the top number:
4-2=2
| Place value | ones | . | tenths | hundredths | thousandths | ten thousandths |
| 6 | . | 0 | 4 | 3 | 8 | |
| - | 3 | . | 3 | 2 | 0 | 0 |
| . | 2 | 3 | 8 |
Because the upper digit (0) in the tenths column is too small to get a positive difference, borrow 1 from the digit (6) in the next number place which becomes (5) and get (10).

The solution is: 2.7238
