Here are some examples that come to mind:
- You are in a library and there is a secret door. You take time to look at the books and get an idea of what is here. As you are here a few minutes, you notice a draft coming from the northern wall. You aren't sure where the door is specifically, but you are pretty sure the draft has to be evidence of the door. You then try to figure out how to get it open, which is something you are actively doing and thus roll investigation. On a success you notice a statue of a bust can have its head twisted and the door opens. If you had failed the roll and never said "I mess with the bust" then the roll represents you not considering that possibility and giving up before trying it.
- You walk down a hallway and your passive perception helps you notice soot on the walls. If you didn't have a torch you might not have noticed (-5 to PP if using darkvision in darkness). You use investigation at a safe distance and deduce that some of the floor panels cause the walls to slide and reveal flame jets. You then either jump far enough to jump over all the plates or use thieves tools to see if you can jump the pressure plates so they will stay put under your weight. if you failed the thieves tools, you either damage your tools or "think" you did a good job and find out the hard way you didn't.
As for things like passive insight, you might talk to someone and your passive insight is your "gut feeling" of if they are friendly, neutral, or hostile and if they are faking or hiding anything. However, you might need to actively roll insight to see why your gut tells you that. Perhaps they have a tell you didn't see until now, like ringing their hands or scratching an ear.
As for stealth, I mentioned earlier but if you sneak up on someone who is unaware of you, it is active stealth vs highest passive perception of those who could see/hear you. If you are in combat and you meet the condition of 3/4 or full cover or heavily obscured or invisible and make an active stealth roll, it is compared to the highest passive perception of those who would not want to lose track of you. On a failure, someone might go "hey, he's trying to get away!" and point you out of there are different passives. Once someone is hidden, unless they give away their location (typically attacking or casting a spell with a verbal component, etc.), you must use your action to perform an active perception check against the active stealth check they rolled earlier. Generally, hiding is easiest against distracted enemies. If someone attacks someone other than you or seems to be doing things actively that don't involve you, they are probably distracted, but they still get their passive perception.
