Multiple correction burns along the way. For equivalent burns, the later along the trajectory the burn, the smaller its net effect on final position. So it's a series of increasingly better approximations. Try it in ksp. It's quite illuminating to plan your burns and see their effect graphically and build an intuition for celestial mechanics and astrogation.
