Well in the end it will of course not be a counter multiplying exponents until the exponent multiple reached. One must use a divide & conquour search setting min and max, closing in until the digit found. A counter upto 9007199254740992 would be a long wait to find the right digit ;). But i feel comfortable i will be able to use 1000 digit bases in the end. Do arithmetic such as mult and div upon very big numbers. And that is why i use my naive approach.
