time converting

Hi! I am learning programming in C and I am trying to make a programme to convert the seconds in days, hours, minutes, and remaing seconds.
I have been discussed this problem earlier and got good response but I'm still unable to find the desired result.

I am using code like this

int s,m,h,d;
printf("Enter the number of seconds and press return:");
scanf("%d", &s);
// calculating the number of days
d=(((s/60)/60)/24);
printf("total days are %d",d);

Now I want to calculate the remaining seconds in hours, minutes, and seconds.
Can any one help me.

Code:

---

itsme@dreams:~/C$ cat timebrkdwn.c
#include <stdio.h>

#define SEC_PER_MIN  60
#define SEC_PER_HOUR 3600
#define SEC_PER_DAY  86400

int main(void)
{
  int s, m, h, d;

  printf("Enter the number of seconds and press return: ");
  fflush(stdout);
  scanf("%d", &s);

  // Days
  d = s / SEC_PER_DAY;
  s %= SEC_PER_DAY;

  // Hours
  h = s / SEC_PER_HOUR;
  s %= SEC_PER_HOUR;

  // Minutes
  m = s / SEC_PER_MIN;
  s %= SEC_PER_MIN;

  printf("Days: %d, Hours: %d, Minutes: %d, Seconds: %d\n", d, h, m, s);
  return 0;
}

Code:

---

itsme@dreams:~/C$ ./timebrkdwn
Enter the number of seconds and press return: 923874
Days: 10, Hours: 16, Minutes: 37, Seconds: 54
