I find it hard to believe that you use much division is Zope scripts,
but if you do, use divmod(x, y)[0] for int division and x*1.0/y for
float division.

However, Zope typically comes with its own Python version, so all you
need to do is not upgrade the Zope version you are using.  Also, I
believe that Zope is typically much more aggressive in breaking old
code, so you wouldn't want to upgrade your Zope anyway if you had a
lot of old code around that you couldn't afford to maintain.
