Most explanations of true count calculation simply say that the running count is divided by the number of remaining decks in the shoe.

Also asked, how does card counting give you an advantage?
The first thing worth noting about card counting is that it isn't this ultimate blackjack strategy that gives players a 20% edge over the house. Instead, most good card counters only gain a 0.5% or 1% advantage over casinos. And with such a small edge, card counters suffer plenty of downswings along with the profits.
