I got lost at % . Can someone expand on how/why/when to use %?

Why would one use % instead of / ? I'm not sure if it's my lack of maths here but I just couldn't work out how one would see if a number is divisible by another. Can someone give other options on how this could have been done to see if I understand it better?

Thanks a mil!

Division will be done with /, Example 4/2 = 2

Modulo operation will give you the remainder, meaning if your are able to divide a number by another will give you 0 Example, You can divide every EVEN number by 2, So if you use 10%2 will be equal to 0 since 2 "FITS" in 10 an exact number of times. In this case it "Fits" 5 times. Same goes for the other numbers. 21%3 =0 but 21/3= 7

For this challenge, '''if number %3 ==0: ''' means the number can be divided by 3, since 3 fits an exact number of times in that number.

Hope this helps!

The % operator gives you the remainder of the division. So it will always be 0 when you use it on numbers where one is evenly divisible by the other.
