Divide big numbers

*amp*rea

hello,

I have get through this problem, I want to divide these numbers but the result calculated by c++ is not right. I am quite sure it is due to the type of the variables but I don't know how to solve it.

unsigned long long u40=16825420246;
	unsigned long long u20=3171426;
	unsigned long long prod=u20*u20;
	double kx; //I have also proved with float but the problem still remains

	kx=u40/prod;

Could anyone of you help me?
Thanks in advanced!

maybe

kx = (double)u40/prod;

helps
