The key problem here is that the original question is, to put it
frankly, too naive to be answerable in a serious way. There is no
"best method" of removing seasonality independent of any other
details. Indeed in many contexts and for many purposes seasonality is
interesting and important and deserves to be modelled directly.
Chocolate sales strike me as a very plausible example.

That said, Yuval pointed to one serious method, and it is well
documented. So quite what the second question is asking remains
