Solution - Long subtraction
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 | . | tenths | hundredths | thousandths | ten thousandths |
| 1 | 4 | 3 | 2 | 7 | . | 8 | 1 | |||
| - | 2 | . | 6 | 3 | 8 | 2 | ||||
| . |
Put zeros in the blank number places:
| Place value | ten thousands | thousands | hundreds | tens | ones | . | tenths | hundredths | thousandths | ten thousandths |
| 1 | 4 | 3 | 2 | 7 | . | 8 | 1 | 0 | 0 | |
| - | 2 | . | 6 | 3 | 8 | 2 | ||||
| . |
2. Subtract the numbers using long subtraction method
Because the upper digit (0) in the ten thousandths column is too small to get a positive difference, borrow 1 from the number to the left (10) which becomes (09) and get (10).

Subtract the numbers in the ten thousandths column from the top number:
10-0-2=8

Subtract the numbers in the thousandths column from the top number:
9-8=1

Because the upper digit (0) in the hundredths column is too small to get a positive difference, borrow 1 from the digit (8) in the next number place which becomes (7) and get (10).
