  Anything that triggers during the resolution of this will wait to be put on the stack until everything is put onto the battlefield and resolution is complete. The player whose turn it is will put all of his or her triggered abilities on the stack in any order, then each other player in turn order will do the same. (The last ability put on the stack will be the first one that resolves.)

  In a game of N players, the process ends when all N players in sequence (starting with you) choose not to put a card onto the battlefield. It doesn't end the first time a player chooses not to put a card onto the battlefield. If a player chooses not to put a card onto the battlefield but the process continues, that player may put a card onto the battlefield the next time the process gets around to him or her.
