Cls
Dim n() As Byte
Dim r() As Byte
Dim b As String
Dim c As Byte
Dim i As Long
Dim L As Long
L = Len(Me.Text1.Text)
ReDim a(L)
For i = 1 To L
    b = Mid(Me.Text1.Text, i, 1)
    a(i) = Int(Val(b))
Next i
c = Int(Val(Me.Text2.Text))
Dim d As Byte
Dim t As Byte
ReDim r(L)
For i = L To 1 Step -1
    t = a(i) * c + d
    r(i) = t Mod 10
    d = t \ 10
Next i
If d <> 0 Then
    Print d
End If
For i = 1 To L
    Print r(i)
Next i
End Sub
