Does just making one of the columns on the report a formula field and doing the calculations in there not work for this? I thought using a calculated column to add up other columns on the reports worked too, I am almost positive I have summary reports like that.
It's possible I am missing something obvious here though. It sounds like you want something pretty simple, a column that will divide column 1 by column 2 and have the result in the 3rd column. Is that right?

The issue is that if you have a record with 1 defective widget out of 2 produced that is a 50% failure rate, and if there is another batch (record) of widgets with 100 items and 1 failure that is a 1% failure rate.
If you average the failure rates then the average would be a 25% failure rate (Averaging 1% and 50%) when in fact its much closer to a 1 % failure rate for all widgets produced. So an Average of Averages is not mathematically correct as it needs ot be a weighed average.
