You can also divide the plant into 2 using the stems. To do this, remove the leaves at the lower part of the stem and place them in the soil. Cover it with a healthy layer of earth (about 1.5-2"), and keep the top of the plant vertical. New roots will emerge from the stem at which point you can remove them from the original plant.
