Give Location of Cells (coordinates)

I need to know how to find out the 'coordinates' of calculated values in a 'custom' coordinate system. I found an equation to find the 1st highest number in a set of data and I would like a formula/macro/etc to also give the corresponding coordinates of the 'axes' of the table. (Numbers 1 through 80 as shown in the picture)

Any thoughts?
