Handle things in Simultaneous Frames, with varying time depending on what they're doing. For "zoomed-in" exploration (such as a dungeon, camp, etc), I handle things in 1 to 5 minutes frames usually. I'm still polishing the mechanics but overall, here is the idea: Pop up the turn tracker and have each PC roll initiative. This is the initiative will be used should combat occur at any point during the exploration. Put an "Events" token at initiative 0, that'll mark the end of the turn. Each PCs in turn move up to 2x their movement and declare any action, such as "check this area for traps" or "check this chest and loot it", "study the arcane glyphs", etc. When you reach the "Events" turn, resolve everything simultaneously, describe what happens, handle dice rolls, hand out what is found, etc. Keep going through the turns. PCs can agree to get out of the frames or change the time frames if they want to rest, study something for a long period of time, etc. Likewise, if the PCs are simply "advancing" through a dungeon, I only handle frames mainly for the Leader (the one in front), while the others can basically move and do whatever as long as they remain behind the point man, within reason. It can get a bit overwhelming to handle. If so, simply resolve actions briefly as the PCs declare, then sum things up, with the appropriate consequences, during the Events turn. That said, if a player's being an ass, he's being as ass...
