I have a question on a very basic operation of modulo operator.
Why does 1 % 9 produce 1? If 10 % 9 then remainder is 1.

I am very poor in math but have had to use modulo operator
many times before but always become confused and couldn't
understand the logic when dividend is smaller than divisor.

Thank you.

Well 9 divides into 1 zero times with 1 left over.

I got the point.
Thank you very much for the help.
