My captain and I were enroute on our IFR flight plan when we experienced a total hydraulic failure. It started when we began to lose pressure in the hydraulic system; and then ran the required QRH procedure. This fixed the problem for only a few moments before a 0 psi indication was observed. Our landing gear deployed because the hydraulic pressure could not keep it up in the gear wells. It was after this that we could not maintain our cruise speed; and our fuel required us to divert as well [as] look for the longest runway possible to stop the aircraft because of severely limited braking. Our expectation was to have only 6 brake applications from the emergency brake accumulator per the manufacturer and our training. We told Center that we needed to divert for both braking and fuel reasons; and they asked if we [would need assistance] because we might be shutting down the runway due to limited braking and might need to be towed off. We then [requested priority handling] and diverted to ZZZ and landed. Upon landing; we cleared the runway under our own power and the brakes had some pressure left. We stopped on the taxiway and were inspected and chocked by ZZZ operations.After no damage was observed to the aircraft and all individuals were deemed safe and not in need of medical attention; we were able to taxi under our own power. We then talked to our company operations and grounded the aircraft for maintenance. My captain and I debriefed the situation.Always be learning and applying the SOP's; and take your time. My Captain and I did all those things and conferred with one another on the best course of action; and determined because of limited fuel and range (even though we took off with well over the legal minimum); as a result of the gear deploying; we made the best and the SAFEST decision possible in the moment; and had the best outcome. Safety is ALWAYS the only priority.A good pilot is always learning!
