The principle of binary representation and translation from binary to decimal are straightforward. That assumes binary. It could be in any base to begin with. It could be in base 10 already and the task is to convert TO binary. After all, 1001 is a number in base 2, 3, 4, etc.
I don't see why it begins with a zero. If it is one binary number, there is no need to state a leading zero unless it is the readout of an 80 digit register. If it is two numbers, the same question applies.
So you have a procedure in mind? Expressing such large numbers (powers of 2) and adding them could be tedious.
