How to use very big numbers on c++?

Question

Hello guys,I have got very interesting question,how do we use large numbers.I think the biggest integer that c++ can hold is "unsigned long long int".Also "double" can handle large numbers but we can't use "%" on doubles.There is "fmod()" function which takes mod of doubles but that is not correct.Is there anyway to patch c++ large numbers?If yes please show me how to install it.I am using devcpp 4.9.2 on windows.
