Quick answer
Check the denominator when a formula divides by zero or a blank value. Decide what missing input should mean before choosing an error handler.
Understand the issue
An average or rate with no valid denominator should not silently become a trustworthy zero. Ask the workbook owner how incomplete records should be displayed.
Step-by-step checks
- Identify the denominator cell.
- Check whether zero or blank is intentional.
- Correct the input or use an explicit missing-data rule.
