the only tricky frame is the first one you pull. I often select the second in. As peter said: Pry away the adjacent frames a few mm and take care to lift the frame up and out vertically, slowly and smoothly. Then I use a frame rest (or a spare box) to hold that frame outside of the hive. Others merely lean it somewhere. Before you hang or lean it- you can use the sharp up/down shake right above the box so the majority of bees on the frame fall down back into the hive. You don’t have to do this. It can be good to shake bees if you are interested to look for eggs, larvae- so you cna see the comb better. Always take care you don’t accidentally put the queen outside or shake her on the ground if you can. Most times she wouldn’t be on an outer frame but she may be.
Then you can use the space you have created to move frames over a little before lifting them out working your way across the box. when you are done you carefully push the frames all back to how they were to keep the spacing between frames nice and even. Clean bridge and burr comb as you go. Over time if you inspect regularly and keep things straight- the box become more manageable and ordered.
