in thread Surviving 'Illegal division by zero'

I agree, especially from the viewpoint of maintainability. Better to handle such situations (there may be cases other than division by zero which need special attention) in one encapsulated place. The other choices are to dig through all the code, restructuring where needed to handle the exceptional case, or to try to capture the exception (which tells you when the problem has happened rather than letting you avoid it).
