The fraction ↉ was introduced for the game of baseball, to represent the tenure of a pitcher who appears in a game, but retires no batters. This illustrates how some Unicode characters have been introduced for highly specialized purposes.

Unicode provides several symbols that might be employed in conjunction with division:

A ratio might be written in these three equivalent ways:

source result
6 ÷ 3 = 8 ÷ 4 6 ÷ 3 = 8 ÷ 4
6 ∕ 3 = 8 ∕ 4 6 ∕ 3 = 8 ∕ 4
6 ∶ 3 ∷ 8 ∶ 4 6 ∶ 3 ∷ 8 ∶ 4
