Since you asked : ). It is really quite easy, once you get the hang of it. The room must be squared (you can google that, this is hard to explain without a diagram - no linear measurements (tape measures) are used). A vertical plumb bob (or a string with a nail on it!) marks the final corners that will be the finish plaster. A rough coat with lots of coarse sand is gently squeezed through the moistened lath. Usually a second coat, applied by hand to make it smooth by eye. On the final coat a piece of wood or metal strips called "screeds" are placed exactly in line with the plumb bob strings. Then a long flat metal blade, called a "Darby" uses these these strips like a guide rail and slide up and down on the final layer of plaster. The wood guides are removed, the metals sometimes stay as 'expansion joints'. Sometimes the corners are covered with special metal lath before final plastering. The final plastering is just making everything right, correcting any imperfections. Experienced crews, in not no demanding work, used a long flexible piece of plastic or metal called a "Slicker" and can get a reasonably flat surface without using 'Screeds'. These same techniques can be used in cement stucco and finishing work as well. Screeding plaster is much easier than screeding concrete.
Today, mostly galvanized steel is used, and there is a dizzying selection of materials right up to a high security product for prisons, etc.
