题意：问1/n的小数点后第m位是多少。高精度除法。

代码：

# include <stdio.h>


int gao(int n, int m)
{
    int i, dividend=1, quotient, remainder ;
    for (i = 0 ; i <= m ; i++)
    {
        quotient = dividend/n ;
        remainder = dividend % n ;
        dividend = remainder * 10 ;
    }
    return quotient ;
}


int main ()
{
    int n, m ;
    while (~scanf ("%d%d", &n, &m))
        printf ("%d\n", gao(n,m)) ;
    return 0 ;
}
