I am sorry but I couldnt find the solving

/////////////////////// DIVISION FUNCTION ////////////////////
void div ( int pol1[] , int pol1p[] , int pol2[] , int pol2p[])
{
int r=0,z,i,g,j,k,l,dividend[6],rising[6]={0};
for (i=0 ; i<6 ; i++)
dividend=pol1;
for(i=5 ; i >=0 ; i--)
{
if(dividend!=0)
{
for(z=5 ; z>=0 ; z--)
{

if(pol2[z]!=0)
{
*(po5 + (i-z))= dividend/pol2[z];
r++;
for(l=0; l<6; l++)
rising[l]=0;
for (j=z ; j>=0 ; j--) {
rising[i+j-z] += (*(po5 + i-z) * pol2[j]);
}
for(k=0; k<6 ; k++) {
dividend[k] = dividend[k] - rising[k];
}
}
}
}
}

this is my code, its for 2 poly which max power is 5 and I have to
divide them but it sometimes divide right,sometimes divide wrong,
can you see the problem?

You have already been told at least twice that your function's name clashes
with the name of a function in the standard library. Since you haven't
shown any sign of understanding and heeding that advice, you'll find it
hard to persuade anyone that it's worth trying to help you with advice
that may turn out to be even more complicated.
