This is so, so, easy:

--put the three flop cards back on top of the deck IN THE ORDER IN WHICH THEY WERE. To do this, the dealer must completely "undo" everything he did.

For example, if he's a right-handed dealer, and he spread the flop to the right (in a way that the top card slid furthest to the right, and the middle card ended up in the middle), he needs to slide it back to the left into one pile, being careful to keep them in their original positions; turn the pile face down; and put the cards, one at a time, back on top of the deck.

--the card on top of the deck now is the turn card. The next card is an exposed burn card. The following card is the prematurely exposed river card.

--Put out the turn card. Show everyone the exposed burn card, then put it face-down with the other two burn cards.

--Show everyone the exposed river card, and tell them that it will be shuffled back in, if necessary.

--Resume the action on the turn.
