# Just a Numble

Now give you two integers n m, you just tell me the m-th number after radix point in 1/n,for example n=4,the first numble after point is 2,the second is 5,and all 0 followed

Each line of input will contain a pair of integers for n and m(1<=n<=10^7,1<=m<=10^5)

Each line of input will contain a pair of integers for n and m(1<=n<=10^7,1<=m<=10^5)
