unsigned long % operation

[asilter]

unsigned int nBolum = 0;
unsigned long nKalan = 0L;
unsigned long ulA = 0L;
unsigned long ulB = 0L;
...
        printf("ulA=%u\n",ulA);
        printf("ulB=%u\n",ulB);
        nBolum = (unsigned int) ulA/ulB;
        nKalan = (unsigned long) (ulA%ulB);
        printf("nBolum = %u\n",nBolum);
        printf("nKalan = %u\n",nKalan);
        ...

it prints;

ulA=2607503366
ulB=16777215
nBolum = 155
nKalan = 7100321

to the screen.

But the nKalan value(the remaining value from the division) must be 7035041. why is it calculating it wrong?
what is the problem?

thanks

No idea, but first some warnings.

gcc -W -Wall -ansi -pedantic -O2 foo.c
foo.c: In function `main':
foo.c:10: warning: unsigned int format, long unsigned int arg (arg 2)
foo.c:11: warning: unsigned int format, long unsigned int arg (arg 2)
foo.c:15: warning: unsigned int format, long unsigned int arg (arg 2)

That fixed, it seems fine to me

#include<stdio.h>

int main(void)
{
    unsigned int nBolum = 0;
    unsigned long nKalan = 0L;
    unsigned long ulA = 2607503366UL;
    unsigned long ulB = 16777215UL;

    printf("ulA=%lu\n", ulA);
    printf("ulB=%lu\n", ulB);
    nBolum = (unsigned int) ulA / ulB;
    nKalan = (unsigned long) (ulA % ulB);
    printf("nBolum = %u\n", nBolum);
    printf("nKalan = %lu\n", nKalan);

    return 0;
}

$ gcc -W -Wall -ansi -pedantic -O2 foo.c
$ ./a.exe
ulA=2607503366
ulB=16777215
nBolum = 155
nKalan = 7035041
