The first line of defense against difficult to understand error messages is to put near the top of your script the following line: 
use diagnostics;

And when you do that, using your existing script, the terse error message will become the following more verbose and descriptive message: 

Illegal division by zero at (eval 15) line 4 (#1)
    (F) You tried to divide a number by 0.  Either something 
    was wrong in your logic, or you need to put a conditional
    in to guard against meaningless input.

Uncaught exception from user code:
    Illegal division by zero at (eval 15) line 4.

To take advantage of the best Perl has to offer in error messages, warnings, and diagnostics, be sure that your script, at least while under development, starts out with: 

use strict;
use warnings;
use diagnostics;
