I have a problem and can't solve it alone. My teacher gives me one logic task today, and i'm sure you can help me.

How can I count the number of zeroes at the end of factorial(41). (on paper) I understand that it has nothing to do with programing, but I'm sure programers can help me.

Thanks in advance.
