题解：

 1 #include <iostream>
 2 #include<string>
 3 using namespace std;
 4 const int MAXN = 1000 + 5;
 5 
 6 int main() {
 7     string str;
 8     int b;
 9     cin >> str >> b;
10     if (str[0] - 48 < b&&str.size() == 1) cout << 0 << " " << str[0];//比如3/8这种情况单独处理
11     else {
12         int ans[MAXN] = { 0 }, k = 0, temp = 0;
13         for (int i = 0; i < str.size(); i++) {
14             int cnt = temp * 10 + str[i] - 48;
15             ans[k++] = cnt / b;
16             temp = cnt % b;
17         }
18         if (ans[0] == 0)//首位是0不能输出
19             for (int i = 1; i < k; i++)
20                 cout << ans[i];
21         else
22             for (int i = 0; i < k; i++)
23                 cout << ans[i];
24         cout << " " << temp;
25     }
26     return 0;
27 }
