This division test was too stringent in its accuracy expectations for 

random inputs:  if you ran the test 100 times, you could expect it to
report a bogus failure.  So loosened its expectations.
Also changed the way failing tests are printed, so that when run under
regrtest.py we get enough info to reproduce the failure.
