Real advanced 3-2 on aggregate, although an uncharacteristically humble Madrid manager Jose Mourinho admitted the win was undeserved.
"The best team lost, independent of the sending-off," he said.
The match took a controversial twist when Manchester United were reduced to 10 men with over half-an-hour to go - Nani seeing red card for a high tackle on Alvaro Arbeloa.
Real, who were one nil down before the sending off, grabbed two goals to seal their advance.
Luka Modric scored the first with a beautiful effort and then came the Ronaldo show, the Portuguese star adding the second.
