// operator is a floor division, so it will just keep the whole number part of the result and discard decimal part.
% is modulus operator, which returns a remainder when you divide two integers. e.g. 7 % 2 -> 1 ( 7 / 2 = 3, 1 remains to 7).
Knowing this, the code is quite easy to understand. I recommend you to take pen and paper, make up a number you will use for initial "seconds" parameter, and do the calculations line by line (of course you can execute single lines in python console too).
