In its most basic form, you steer the front wheel to the left to make you “fall” to the right, then once “fallen” enough into the turn, you steer enough to balance you in the turn. To end the turn you steer the front wheel into the turn, this will make you “fall” out of the turn, then steer again to balance yourself.

IRL, there are several ways to do a turn where the bike angles will make this or that method more viable. Example: In MTB you lean the bike heavily into the turn while leaning your body out of the turn, this forces the edge of the tire to bite in the ground giving you a lot more grip (very nimble bike, can be shifted easily, bike geometry is made to make it fall in the turn instinctively). In road motorbike you lean the body in the turn, then the bike, but your body is always weighing the bike into the turn, while steering outward to make the bike fall more in the turn (heavy bike and high speed, needs a lot of force to win the wheel gyro effect and change the bike attitude, bike geometries are made to keep it upright and stable).
