Precision calculation

Octal decimal to re-write the subject, found the problem, not just binary conversion, but I'm not familiar with high precision / large numbers to calculate a relationship.
By this questions, we summarize some of the high-precision points / large numbers calculated:
String operation ①
② each time operation, only bits (single digit) is calculated
③ test field when writing, written calculation process, and more testing, consider a variety of boundary conditions.
At the suggestion of some chiefs of the students, I decided to finish this question, the hand line and large numbers arithmetic operations.
First, octal, decimal
First, for the high precision / large numbers calculated, when using the C ++ language, double, and the like have int accuracy limitations, so there is generally a string selection operation, to be noted here that, through the string, each time only a process of calculating operations can be a character, otherwise due to the variable-length strings, calculated with high accuracy becomes dummy, with the use of double, int no difference. (Already mentioned above)
This question with a simple division of large numbers this thing, this question divisor 8 (so not too complicated), the main point is basically to
1) first determine dividend integer or floating point, with to string.find has ()
2) storing an integer remainder when f is calculated as storage
3) Finally, if this does not begin with 0 decimal .1283 appears, make up the leading zeros
4) calculating, when Note operation will not divide up 0
