Solution - Long subtraction
Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths | ten thousandths | hundred thousandths | millionths | ten millionths |
| 1 | 4 | 9 | . | 3 | 3 | 3 | 3 | 3 | 3 | 3 | |
| - | 4 | 9 | |||||||||
| . |
Put zeros in the blank number places:
| Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths | ten thousandths | hundred thousandths | millionths | ten millionths |
| 1 | 4 | 9 | . | 3 | 3 | 3 | 3 | 3 | 3 | 3 | |
