Dividing by zero

Does anyone know how to include as a script maybe an "echo" warning that explains that if a user uses the second number "zero" when dividing, that the result will BE "zero."

I need, example: 5/0 (second number) = 0, in script form.

current script:
Code:
echo "Enter a number"
read num1
echo "Enter another number"
read num2
div=$(num1 /num2)
echo "div=$div"

thanks,
joe.
