Madara “dies” again in Episode 474, after Kaguya's defeat, as his soul returns to the afterlife and he says a goodbye to Hashirama.
Hashirama Senju, aka the First Hokage, was the only one who could ever beat Madara Uchiha in life. In death and resurrection, Madara gained access to powers he could never gain in life. However, the First Hokage did famously beat Madara in a duel at the Final Valley and seemingly killed Madara.
Madara didn't die from Black Zetsu. In the scene, Black Zetsu stabbed Madara in the chest and made him absorb a lot of chakra and converted Madara into Kaguya Otsutsuki. Then he became Kaguya's vessel until the last second when Kaguya was sealed away. Madara's body was shot out from the Ten Tails Kaguya.
Uchiha Madara died twice in Naruto series. 1) His natural death. When he was battling with Hashirama Senju AKA First Hogake (his best friend), Madara got stabbed in the back by him but didn't die. He used Izanagi beforehand in his right eye in case he lost to Hashirama which he did.
Madara was “defeated” by Black Zetsu in episode 458 of Naruto Shippuden. Madara resurrects himself fully by sacrificing the defeated Obito and ordering Black Zetsu to take control over Obito's body to perform the Samsara of Heavenly Life Technique.
Upon returning to the field, Madara succeeds in casting the Infinite Tsukuyomi. The entire world becomes trapped in the dream. Sasuke manages to save Naruto, Kakashi, and Sakura from this Illusionary Technique, and Black Zetsu stabs Madara, gaining control over his body.

It depends on your definition of a win or a fair fight… but, when you include Dawn of Justice, at least 4 Batman wins to 12 Superman wins: Superman wins 3/4 of all of their fair duels.
Goku has died 5 times total, but twice in the canon timeline. He sacrificed himself to defeat his brother Raditz and he used Instant Transmission Semi-Perfect Cell's self-destructive blast.
