Non-length limit large number operation

Calculation of large numbers is the foundation technique to the procedure of computer encryption and decryption. Unfortunately, the operation capacity of our today´s computers cannot satisfy our needs. In another word, computer software today cannot perform the calculation of large number that incorporates hundreds or thousands of digits to accuracy. In particular, division of large numbers is the hardest out of all basic calculations functions (that includes: Addition, Subtraction, Multiplication and Division). In our traditional way of calculation, obstacles exist when we perform division, in particular through the trial method to obtain an accurate dividend. This paper presents the method to calculate division of large number with simple algorithm and straight-forward concept, which can be applied on both microcomputers and single-chip microcomputer. This method of calculation to calculate division of large number has not been attempted by other academic researches. Therefore if would like to share my findings in this paper.
