Extended data, such as 42 divided by 7.

For example, if 4 is not divisible by 7, then use the highest bit and the next bit to synthesize a number to be divisible until the dividend can be divisible; For example, if 4 is not divisible by 7 in 42, then 4 and 2 are combined into a number. If 42 is divided by 7, the quotient is 6.
