There is no more zeros needed, you can already divide it into 100M individual units which are Satoshis. If the price goes up people can use Satoshis (which already is happening btw), as of now for one Satoshi to be worth $2.40, 1 Bitcoin needs to be worth $244.000.000,00.
Fixed that for you.
You seem to be from a country that uses a period for digit grouping instead of a comma?
Well i don't think people are going to say satoshi, give me 1 satoshi, its a stupid name for money with all respect for bitcoins creator. Bits is much more suitable, i'm from europe and we use comma but since the majority here is from us/uk (i think) i used period.
