OK here we go, if you don't understand it I'll try and explain things to you another time as I'm in a bit of a rush at the moment. It's hard to explain things like these over the Internet, much easier in real life. Hopefully it'll all come back to you. And as a note, once you've added your first 0 put a decimal point in the answer. And also, put any whole number remainders on top of the number your dividing by and then you've got a new number. E.g. remainder of 8 going ontop of the number two now becomes 82, so x/82 it becomes.
Sorry. I've felt like I've explained this really badly - but I've tried.
