You are using wrong operator.
The \ Operator returns the integer quotient of a division. For example, the expression 14 \ 4 evaluates to 3.
The / Operator (Visual Basic) returns the full quotient, including the remainder, as a floating-point number. For example, the expression 14 / 4 evaluates to 3.5.
