Abstract: This paper presents the algorithm and Calculation program about the division of larger integer. The program is brief but functional enough. Just a few statements can achieve the division operation that the dividend with more than ten thousand digits divides the divisor with thousands of digits in 3 to 5 seconds, which has been verified correct .The innovation of the program is that it not only employs array to store larger integer ,which breaks through the limitation of integer store in computer, but also only uses subtract to obtain the quotient ,which Simplifies the operation process and reduces the complexity of the program. The principle of program is simple, and the computing speed is high efficient. In short, the program has large significance in the field of information security.
