When I Run my app, I get a pop up box saying this 'Arithmetic operation resulted in an overflow'. Here is the code;

Try
FSUIPCConnection.Process()
' OK so display the string
' With strings the DLL automatically handles the
' ASCII/Unicode conversion and deals with the
' zero terminators.
FuelTankLCapacity.Value.ToString("F1")
Dim LeftTotalFuel As Integer = (FuelTankLCapacity.Value * 8388608) / LeftTank.Value
Me.Label8.Text = LeftTotalFuel
Catch ex As Exception
MessageBox.Show(ex.Message, AppTitle, MessageBoxButtons.OK, MessageBoxIcon.Error)
End Try

Can i get a bit of help of how to fix this issue? Thanks
