Division of duties on an airliner

I figured this group would have more airline pilots than the sim

I don't think active flight crews have the free time to read/post. The
sim groups have a couple of retired airline Captains, as you know, who
do have more time.

Your question encompasses a lot of subtopics, and is different for each
airline, which is why you're being pointed at Googling to find and read
related websites.

The general answer is common sense. While one person flies, the other
usually takes over the non-flying duties such as navigation, radio and
checklists.
