Set a heavy fry pan over heat so that it heats evenly and thoroughly.
Cut the meat into bite sized pieces - the size you want to use in stew, soup, chili, or whatever.
When the pan is heated well, add oil. When the oil shimmers, add beef cubes in a single layer, so that they each sit on the hot pan to sear. Do not crowd the pan.
After 2-3 minutes, when the meat has browned, use a spatula to turn them. Repeat every couple of minutes, still on high heat, until most surfaces have been browned. Remember, you do not want to fully cook the meat - just brown the surface.
Remove beef to a heat proof dish to cool, repeat the process, in several more batches, until done.
Once meat has cooled, package it for the freezer, and freeze. Use later in recipes that call for browning stew meat.
