输入两个不大于100000的正整数a和b，输出a/b的结果。当然，不是只输出整数部分，小数部分也是要算出来的，不过因为是整数，

如果结果是无限小数，结果一定是循环小数，必定存在循环节，比如1/3 = 0.33333....，或者1/7 = 0.142857142857...，

所以如果是循环小数，那么仅仅输出到第一个循环节结束就可以了，如果不是循环小数，则把精确结果输出（多余的末尾0不要输出）。

输入

仅一行输入，包含两个整数a和b，中间以空格分开-Not more than 100000 enter two positive integers a and b, with the output of a/b results. Of course, not only the output of the integer part, fractional part is to be counted out, but because it is an integer, if the result is an infinite decimal, the result will be a recurring decimal, surely there is a circular section, for example, 1/3 = 0.33333 ...., or 1/7 = 0.142857142857 ..., so if it is a recurring decimal, then the only output to the end of the first loop section can be, if not a recurring decimal, put the exact result output (0 Do not end the extra output). Enter only one line of input contains two integers a and b, separated by a space
