What I have tried:

Application.Range("o7").Activate
'count of the data is stored inn the variable
Application.Range(Selection, Selection.End(xlDown)).Select
a = Application.CountA(Selection)
Range("o7").Activate
'loop function is used till the count of the data
For i = 1 To a
ActiveCell.Offset(0, 1).Activate
b = ActiveCell.Value
ActiveCell.Offset(0, 1).Activate
c = ActiveCell.Value
ActiveCell.Offset(0, 1).Activate
e = (c / b) * 100
'values of the data are stored in a variable and for calculating the SAMPLE COMPLIANCE another variable is used
ActiveCell.Value = e
ActiveCell.Offset(1, -3).Activate
Next
Application.ScreenUpdating = False
End Sub

Why can't you check if b is greater than zero? Am I missing something here?

Simple: don't divide by zero.

Which means: check your inputs.

VB

b = ActiveCell.Value
ActiveCell.Offset(0, 1).Activate
c = ActiveCell.Value
ActiveCell.Offset(0, 1).Activate
e = -1
If b <> 0 Then
	e = (c / b) * 100
End If
