import java.lang.Math.*;
public class Main
{
public static void main(String[] args)
{
try
{
Scanner in = new Scanner(System.in);
long t=in.nextLong();
for (long i = 0; i < t; i++)
{
long m=in.nextLong();
long number=0;
long ind_pow=(long)((double)Math.log(m)/(double)Math.log(5));
for (long j = 1; j <= ind_pow; j++)
{
number=number+(long)(m/(Math.pow(5,j)));
}
System.out.println(number);
}
return;
}
catch (Exception e) {
return;
}
}
}
