Is there a way that when i enter the number 65.26, the cell will
change the number to .6526?

Is the 65.26 a percentage? If so, you can format your cell(s) as
Percentage... then when you enter 65.26, it will display as 65.26%, but the
actual underlying value will be 0.6526 and that is the value that will be
used in calculations involving the cell(s).
