Runtime exception handling (e.g. Divide by zero) in JVM (Java) or CLR (C #)

Question

How does the JVM work, or in this case CLR (Common Language runtime) divided by zero? Does it check the denominator each time before executing the split statement? Or is it handled by a callback function that is called when the "divide by zero" trap is called by the processor?

Any input would be appreciated.

Thanks Alan
