Instructor and Student were landing on [Runway] XXL at ZZZ airport. The braking conditions were 3/3/3. ATC instructed the student to taxi off of the runway at [Intersection] X1. With the snow it was a harder left turn on the ground; almost a back taxi for theX1 intersection from the runway. The aircraft was turned onto A8 but had to come to a full stop and this allowed for a loss in steering authority on the ground. When going to straighten the nose out to go from back taxiing to X1 to exiting X1; the aircraft brakes became unusable and the aircraft slid to the side of X1 where there was a pile of compacted snow which [prevented] a quick recovery [of] control. An aircraft landed on the runway while [we were] almost exited off the runway at X1. Tower came on and asked if we needed to be towed off and informed everyone that there was a disabled aircraft on the runway. There was no damage to airport property or the aircraft itself. No needed assistance.
Light aircraft instructor reported loss of directional control on a snowy taxiway while exiting the runway.
