Basically, for every block traveled horizontally in the nether, 8 blocks are traveled horizontally in the overworld. The vertical component is normal, though. For every block traveled vertically in the nether, 1 block is traveled vertically in the over world and vice versa.
So, if you were standing in the middle of a portal in the overworld and had the [x, y, z] coordinates [78, 71.62, -129.5], than the same location in the nether would be [9.75, 71.62, 16.19]. You just divide the x and z coordinates by 8. The y coordinate remains unchanged. Undoubtably, you would multiply by 8 when going the other direction, from the nether to the overworld.
Now, sometimes the game places a portal in a different location. This is because a portal can't be placed without any room! If you want your nether portal to be in the right location the best you can do is remove the game-generated portal and place your own in the correct location.
And the most frustrating for players is getting to the correct overworld portal from the nether or to the correct nether portal from the overworld. This is where you want to pay attention.
You will be transported to the nearest portal within a 128 block radius of the destination coordinates (if there's no portal, one will be created). Most likely, your neighbor will have already set up some portals right next door so you will most likely be transported to their portal (or one much farther away). Once in the nether, you will want to navigate to the desired coordinates for your portal and place your obsidian portal there. Activate it and your all done! Go through it and you should teleport to your overworld portal.
The problem occurs when everybody has their own pair of portals in each 50x50 plot. This way, every portal in the nether will be on average 6 blocks from each other. This isn't convenient so it's suggested everybody in a 200x200 area use the same central portal.
Knowing this can help you out when traveling large distances as you'll have to walk 8 times less the distance, saving time.
As for getting stuck, don't go in a portal unless you know where it goes. Be sure portals are set up at the matching coordinates. It's simple once you get the hang of it.
