Help me please? I don’t really get it TT

First, you have to move the decimal point before you divide like normally.  You need to move it so that the left number is a whole number.

So, 6.39/0.9 would turn into 63.9/9.

12.75/2.5 would turn into 127.5/25.  

You just move the decimal how ever many times to the right to make it a whole number.  In this case, it is 1 decimal place.
