Although your aforementioned problem appears relatively legitimate,
attempting to catch an exception resulting from division by zero is a
terribly bad practice.  Try testing to see if the input value (the
untrusted value) is non-zero first instead.  This is what reasonable
programs do (kind of like testing for an object being null before
calling a method on it, rather than trying to catch and handle the
exception which results from calling a method on a null value).
