This question is probably, the integer modulus 9973 multiplication group? Then there is the multiplication inverse.So the title asks $ A \div B \pmod {9973} $ is actually equivalent to asking $ A \times b^{-1}\pmod {9973} $.Just ask for the inverse of B to be OK.The multiplicative inverse of the calculated modulus n can be solved by using the extended Euclidean algorithm, i.e., the following linear congruence equation:$$ Ax \equiv 1 \pmod {n} $$1#include 2#include 3 using namespacestd;4 #defineM
