I have the following column of numbers (column A) that may contain 10,000 + numbers. I need to be able to count backwards and insert 1s that add up to the number in column A. A9 contains a 5. I need B5 thru B9 to contain 1s.  Then A14 contains a 3, I need B12 thru B14 to contain 1s.

Can someone help me with this?
