Insert a decimal point

Thankyou soooooooo much. I was able to use the devide function as well. So easy when one knows how shows how much i know about maths. THANKYOU again

I shall play with the other variations posted by Jetted and OldChippy as they have read my mind re length of digits as well.

almost the same situation as alleyb,
but mine is adding a decimal point in a column of cells.
insert a decimal point after the second number, from the right.
ie. 123456 -> 1234.56, 78900 -> 789.00. (in laymans terms).

thanks.
