高精度除法

给定两个非负整数，请你计算 它们 的商和余数。

#include <iostream>
#include <vector>
#include <algorithm>
using namespace std;
vector<int> a, c;
int b;

int div () {
    int t = 0;
    for (int i = a.size() - 1; i >= 0; i--) {
        t = t * 10 + a[i];
        c.push_back(t / b);
        t %= b;
    }
    reverse(c.begin(), c.end());
    while (c.size() > 1 && c.back() == 0) c.pop_back();
    return t;
}

int main() {
    string x;
    cin >> x >> b;
    
    for (int i = x.size() - 1; i >= 0; i--) a.push_back(x[i] - '0');
    
    int t = div ();
    for (int i = c.size() - 1; i >= 0; i--) cout << c[i];
    cout << endl << t << endl;
    return 0;
}
