You need to split the neutral at the 240v receptacle and must maintain the continuity of the neutral. You do that by "pigtailing" the connections (holler if you don't know what that means). Run a separate neutral + 1 hot leg to a GFCI receptacle's Line terminals. via

Can you split a 240v line?

It is possible to split a 240 volt outlet into two 120 volt circuits. You have to share the neutral in the 240v container and you have to maintain the continuity of the neutral. You do it through coiling the connections. via

Can you run two dryers one breaker?

Dryers are typically 5500W, which is just shy of the 5760 watt maximum for a 30A circuit (240V x 30A x 0.8 for the continuous derate). The only way to share a 30A circuit is using a DPDT switch so only one dryer could possibly be on at once. (Of course this would defeat the purpose of having two dryers.) via
