Help for excel, calculate division of colums by sums

[late347]

I have column from E5 -->E35 which contains values for each box.
another column from F5-->F35 contains values for each box

I have a sums column, H5-->H35,, which contains values for the sums between the E and F boxes (E5+F5=H5 ;;; E6+F6=H6 etc...)

I want a division column inside J5-->J35 which contains division such that the dividend = E column and the divisor = H column.
the division should be located inside the J column (J5-->J35) $J= \frac{E}{E+F}=\frac{E}{H}$

i tried to add function from the "add function" button and "division" but it did not seem to work.

When I drag down the division function, then I only get 1 and 0 as the results of division, even though it is wrong to say that 1/6 = 0

I think I got it done by writing manually into the box what the function would be

1/0's are results of integer type so the cells need to be either float or double formatted.
You can also assign your buttons macros. Something simple like this

Sub Division()
Dim answer As Double
For i = 5 To 35
    answer = Cells(i, "E").Value / (Cells(i, "E").Value + Cells(i, "F").Value)
    Cells(i, "J").Value = answer
Next i
End Sub

Now you can insert code similarly for H formula.
