Currently, I have had Minecraft for a long time and i have experienced bugs and glitches and other crashes, but the seem to go away. however, one has stayed for quite some time, and i cannot play Minecraft anymore now.

The error code for this is
The game crashed whilst unexpected error
The game crashed whilst unexpected error
Error: java.lang.ArithmeticException: / by zero

All that happens is that i play my game, and it unexpectedly closes down.

I don't know what to do.

Its version 1.10.2 modded
