How to get the digits of a number without converting it to a string/ char array?

Question

How do I get what the digits of a number are in C++ without converting it to strings or character arrays?

Answer 1

Since everybody is chiming in without knowing the question.
Here is my attempt at futility:

#include 

template int getDigit(int val)       {return getDigit(val/10);}
template<>      int getDigit<1>(int val)    {return val % 10;}

int main()
{
    std::cout << getDigit<5>(1234567) << "\n";
}
