I think it's best to think about fraction, and see that there's two lines over two lines here, as in a fraction.Also:
- to divide
- to separate
- to distribute
- to allocate
- to distinguish (good and bad)
- part or subdivision
- fraction
- one tenth (of certain units)
- unit of length equivalent to 0.33 cm
- a point (in sports or games)
- 0.01 yuan (unit of money)
