You would have to rewind the film before taking it out if the camera. Some semi-pro & pro level cameras have a setting to leave the film leader out when they rewind...so that you could easily reload the film. You would have to remember what frame you were on...and then advance the film to that position (or just past) when you reloaded the film again. To advance the film back to where you were...just take complete dark photos. To minimize any light getting in...set the aperture very small (F22) and the shutter speed to very fast 1/2000, leave the cap on and maybe put it under a jacket/towel etc.
If you can't set the camera to leave the leader out...you could get a plastic film retrieval tool at a camera shop for a couple bucks.
