I am new to Excel, so please bear with me as I explain my problem.

I am trying to create a cell that will automatically divide the number that
I input by two. I know that if I enter "=A2/B2" in cell C, it will give me
the answer. However, I need this number to be in cell A, rather then C.

What I'm doing is copy and pasting a report from one program into Excel.
The first meathod "=A2/B2" will not work as it will mess with the sequence of
the copy and paste command. Basically I need to copy and past from the
report, and have Excel divide cell "A" by two automatically.

Is there ANY way to do this?

Thanks in advance!
