Louis Armstrong sings in What a Wonderful World
I see friends shaking hands saying how do you do
Why (or when) would friends use how do you do as it is supposed to be a formal answer to an introduction?

The literal use of "How do you do?" to greet someone has been basically limited to the first meeting between strangers for the past 50 years that I know of. It's not really that "formal" in the sense that it wouldn't be used when meeting a friend of your buddy in a bar, but it's not normally used as a greeting between friends, or even acquaintances.
However, the expression "saying how do you do" is an idiomatic way to refer to people greeting each other. It's not that the words are literally said between the greeting parties, but rather someone in a group might say "I'll talk too you later, after I get my how-do-you-dos out of the way," or something similar.
