The DECODE function is useful here. Assume you are going to divide x by y. Then the following DECODE will show that result unless y=0, and then it will show something else:

DECODE(y,0,'N/A',x/y)

You'll have to decide what the output will be if y is zero.

Either that, or consider eliminating those rows where y=0 by including:

WHERE y<>0

in your SQL statement.
