BTC divided to BTC and BCC, and will be divided to BTG and B2X.
No, bitcoin was never "divided" to anything. they just created an altcoin and called it BCC (bitcoin cash). they are also creating another altcoin soon and call it bitcoin gold.
they have been creating lots of other altcoins and were calling it different names, like bitcoin core (BTX), litecoin (LTC), and about 500 others.
all the while bitcoin remains bitcoin. one and only.
1. B2X will become real bitcoin?
we'll have to wait and see

2. More BT* will appear in future?
there have been lots of BT* so far and there will be so much more in the future also!
