Dividing with decimals is easy once you get rid of the decimal point in the number you are dividing by.
- Fix the Outside Number. You want the number you are dividing by (the outside number) to be a whole number. To do this, hop the decimal point all the way to the right. 2. Match it on the Inside
Whatever you did to the outside number, you must do to the inside number. Move its decimal point the exact same number of hops to the right. Example: $12.6 div 0.3$. Change $0.3$ into a whole number by hopping the dot 1 time to the right. It becomes $3$. Do the same to $12.6$. Hop the dot 1 time to the right. It becomes $126$. Now your question is just $126 div 3$, which equals $42$!
