Why do I get these numbers when I have made a range that starts from 7 to 1000000, with 7 as increment number

Question

sevens = range(7, 1000000, 7)

x = int(input("Please enter a positive number less than one million: "))

if x in sevens:
    print("{} is divisible by seven.".format(x))

My question is why do I get the following as output? Why 3510 as the starting number when the ranges begins with 7?

3510, 83517, 83524, 83531, 83538, 83545, 83552, 83559, 83566, 83573, 83580, 83587, 83594, 83601, 83608, 83615, 83622, 83629, 83636, 83643......

Does the error has to do something with the computer memory or is the problem in my IDE(Pycharm Jetbrains)?

Thank you!

Your code and your Output do not correlate. – Patrick Artner Feb 18 '18 at 13:04 — Patrick Artner, Feb 18 '18 at 13:04

To test if a number is fully divisible by another number use the % (aka Modulo) operation that gives you the rest of said division:

x = int(input("Please enter a positive number less than one million: "))

if x%7 == 0:
    print("{} is divisible by seven.".format(x))
    print("It fits {} times.".format(x//7))
else:
    print("{} is not divisible by seven - theres a rest of {}.".format(x,x%7))
