If you think about it, it might work using your hands. Count to 10 using your fingers, then hold up a thumb to represent 10, thumb and a finger to represent 100, etc. etc. Maybe that's how the Chinese came up with the counting system for Chinese, Sino-Japanese and Sino-Korean numbers.
Just remember that you change to a different number "stage" (I guess? Like thousand, then million, billion, etc.) every four powers of 10.
