Regrouping in math with decimals simply refers to the term used addition or subtraction when either carrying or borrowing is involved. Regrouping is used to assist while performing addition and subtraction.

Hence before jumping straight into division. Some time between New Math and Common Core some fundamentalists convinced everyone writing and approving primary mathematics textbooks that it cannot be called borrowing if you never give it back.
