After each player has decided on their discards, the dealer begins replacing their cards in turn. For example, if the first player discards 3 cards, the second player discards 2 cards, and the third player discards 1 card the dealer would deal the first player 3 cards, then take that player's discards into the muck. The dealer would then deal the next player 2 cards then take that player's discards into the muck. The dealer would then deal the last player 1 card, then take that player's discards into the muck.
After the draw is complete, there is another round of betting. The players then have an opportunity to draw again. After the second draw is complete, there is another round of betting. The players then have one more opportunity to discard. After this third and final draw, there is one more betting round.
