Append string with row number

What I'm trying to do is append the row number to the string. This section of code creates numerous rows based on the number of labels desired.
Basically in column A is the project number which is constant, but I would like to add (1/3),(2/3), (3/3)
ie.
9999-999 (1/2)
9999-999 (2/2)

Any thoughts?

Thanks in advance!

n = CLng(InputBox("Please enter the number of labels you would like to create"))
        
        With Sheets("Labels")
            .Range("A1:Z65536").ClearContents
            .Range("A1:A" & n).Value = (project_number & "" & "(" & .Row.Address & "/" & number_labels & ")")
            .Range("B1:B" & n).Value = Customer
            .Range("C1:C" & n).Value = daterec
            .Range("D1:D" & n).Value = Description
            .Range("E1:E" & n).Value = datedisposal
        End With
