Hello,

Do you remember how to do a division at school ?

First, you divide 3 by 11. The quotient is 0, the remainder is 3. Then, put a coma and calculate 30/11. The quotient is 2, the remainder is 8.

etc...

And there will be a time when you will have 3 as a remainder. It'll be the same numbers as previously, and here is the period.
