secs into hours mins and remainin secs

Can anyone tell me a good algorithm on how to convert seconds into hours, minutes and remaining secs ?

I have this source code, but when you enter a bigger value it gets slowed..

Code:

---

#include <iostream>

using namespace std;

int main(void)
{
        int secondsInput, seconds, hours = 0, minutes = 0;
        cout << "enter number of seconds: ";
        cin >> secondsInput;

        seconds = secondsInput;

        int hrs = 3600;
        int mins = 60;

        for ( int x = 1; x <= secondsInput; x++ ) {

                if ( x == hrs) {
                        hours += 1;
                        seconds -= 3600;
                        hrs += 3600;
                }
        }

        for ( int y = 1; y <= seconds; y++ ) {

                if ( y == mins ) {
                        minutes += 1;
                        mins += 60;
                        }
        }

        int z = secondsInput - (( 3600 * hours ) +  ( 60 * minutes )); // z = number of seconds

        cout << "\n" << secondsInput << " equals to " << hours << " hours " << minutes << " minutes " << z << " seconds";
    return 0;
}

Thanks

Code:

---

int nSeconds = 3930;
int nMinutes = nSeconds / 60;
nHours = nMinutes / 60;
nSeconds -= nMinutes * 60;
nMinutes -= nHours * 60;

---

something simple like this should do

Code:

---

int main() {
    int secs = 1234567;
    int h,m,s;
    h = secs / 3600;
    m = (secs - h * 3600) / 60;
    s = secs - h*3600 - m*60;
}
