送你个函数：

string BIGdivsmall(string na,int nb) {
    if (nb == 0) return "ERROR";
    int la = na.size();
    string ans = "";
    string now = "";
    for (int i = 0; i < la; i++) {
        now += na[i];
        int k = stoi(now);
        ans += (k / nb) + '0';
        k %= nb;
        now = to_string(k);
    }
    while (ans[0] == '0') ans.erase(0,1);
    return ans;
}
