Decimal points show place value! Just like in whole numbers, you can only subtract digits that are in the same place value column. Lining up decimals ensures tenths subtract from tenths.
Add zeros to make them the same length! For example, 0.6 becomes 0.60 when subtracting from 0.25. This doesn't change the value but makes alignment easier.
It's exactly the same process! The only difference is you need to keep track of the decimal point and make sure it appears in your answer in the same position.
