Dividing 100% by 3 without any left In mathematics, as far as I know, you can't divide 100% by 3 without having 0,1...% left.
Imagine an apple which was cloned two times, so the other 2 are completely equal in 'quality'. The totality of the 3 apples is 100%. Now, you can divide those 3 apples for 3 persons and you will get 100% divided by 3 and none left.
Is this because                                    1: mathematics is not real                   2: there is no 1 or 2, and it's in fact just an invention for measurements? So,  in the division of 100% by 3 WITHOUT any left, is NOT  accurate?

In base 10, no, not as long as you only allow finite digits. In base 3, we certainly can (or any other base divisible by three).
