Potential Divide By Zero Vulnerability in Darknet Project

[CR7-source]

I have identified a potential divide by zero vulnerability in the Darknet project and would like to report it to the maintainers. This vulnerability has the potential to cause unexpected application behavior, crashes.Can you please help me check it? Thank you for your effort and patience!
