这个就是高精除以低精吧？

```cpp
#include<bits/stdc++.h>
using namespace std;
char aa[25];
int a[25],b,c[25],sa,sc = 1,i,x;
int main(){
cin >> b;
cin >> aa;
sa = strlen(aa);
for(i = 0; i < sa; i++){
a[i + 1] = aa[i] - 48;
}
for(i = 1; i <= sa; i++){
c[i] = (x * 10 + a[i]) / b;
x = (x * 10 + a[i]) % b;
}
while(!c[sc] && sc < sa) sc++;
for(i = sc; i <= sa; i++){
cout<< c[i] ;
}
return 0;
}
```
刚写的代码，我也不知道能不能AC

谢，高精度模运算就是本题原意，可是我测试数据下载下来后试了下.发现~~我的秒出还对~~（
但偏偏提上去是错的

```cpp
#include<bits/stdc++.h>
using namespace std;
char s[100000010];
long long a[100000010],b,c[100000010];
int main()
{
int la,lc;
cin>>b>>s;
lc=la=strlen(s);
for(long long i=1;i<=la;i++)
a[i]=s[la-i]-'0';
int d,r=0;
for(long long i=la;i>=1;i--)
{
d=r*10+a[i];
r=d%b;
}
if(r!=0)
cout<<r;
else
cout<<b;
return 0;
}
