Raise the bottom part of the deck upwards to eliminate and separate it from the upper/top part of the deck. With the help of your thumb hold the upper part while the right hand lifts the lower part of the playing cards deck upwards.
Now, take the lower part that you raised, downward over the upper part, and then press the left thumb to the top of that part at the same time raise your right hand upward again to make another eliminated part and make the part that you hold by your left thumb come on top of the portion that retained in your left hand.
Again get the lifted part downward over the other portion and repeat the exercise until the cards held by the right hand have been shuffled off.
