Bill decided to visit his friend. It turned out that the Bill's house is located at point 0 and his friend's house is located at point x (x > 0) of the 
coordinate line. In one step Bill can move 1, 2, 3, 4 or 5 positions forward.

Given integer x, return the minimum number of steps Bill needs to make in order to get to his friend's house.

Example 1
Input:
12
Output:
3
Example 2
Input:
41
Output:
9
