In TA 1980, a Balrog awoke in Moria when the Dwarves had mined too deep for Mithril. It drove the Dwarves out of their home and slew King Durin VI, and the Balrog was thereafter called "Durin's Bane". Gandalf the Grey fought the Balrog, allowing the Fellowship to escape Moria..
Correspondingly, would the Balrog have joined Sauron?
The Balrogs were originally the servants of Morgoth in the First Age, of whom, Sauron was also his servant. The Balrogs and Sauron were all Maiar and somewhat coeval; it is debatable whether a Balrog would recognize Sauron as successor and serve him willingly. The Balrog was awakened by the Dwarves in the year 1980.
Subsequently, question is, are there any balrogs left? Yes. The number of balrogs has changed in Tolkien's mind. In the beginning they were thousands of them, and they were quite weak. For instance when Feanor is surrended by balrogs, Tolkien thought them as far weaker and numerous than in later writings, such as the LotR.
Subsequently, one may also ask, why did the Balrog attack Gandalf?
He was a "servant of fire". So, in the context of bigger Tolkien Universe, Balrog posed a threat that needed to removed and who better than the leal "servant of fire" to remove that threat!! In the fight with the Balrog, Gandalf removes this big threat to the middle-earth.
Can a Balrog defeat Sauron?
Balrogs are not actually that powerful. In the Morgoth's Ring "Orcs" essay Balrogs are explicitly stated to be less powerful than Sauron. This is borne out by the fact that heroes of the First Age could defeat Balrogs (admittedly dying themselves in the attempt), but Felagund could not overcome Sauron.
