longdivision 0.1

This script can be used as library to split division it to simple steps or as console script to visualise division.

Example usage as command line script:

$ python3 -m longdivision 1/3
_1 / 3 = 0.3333
 0  <- 0 * 3
 -
_10
  9  <- 3 * 3
 --
 _10
   9  <- 3 * 3
  --
  _10
    9  <- 3 * 3
   --
   _10
     9  <- 3 * 3
    --
     1

$ python3 -m longdivision 6359/17
_6359 / 17 = 374.0588
 51  <- 3 * 17
 --
_125
 119  <- 7 * 17
 ---
  _69
   68  <- 4 * 17
   --
   _10
     0  <- 0 * 17
    --
   _100
     85  <- 5 * 17
    ---
    _150
     136  <- 8 * 17
     ---
     _140
      136  <- 8 * 17
      ---
        4

Example usage as library:

>>> import longdivision
>>> list(longdivision.divide_integer_part(5, 2))
[(5, 4, 2, 1)]
>>> list(longdivision.divide_integer_part(1, 3))
[(1, 0, None, 1)]
>>> list(longdivision.divide_fractional_part(1, 3))
[(10, 9, 3), (10, 9, 3), (10, 9, 3), (10, 9, 3)]

divide_integer_part

Iterates over all division steps providing reminder, quotient, result_digit, numerator_position.

divide_fractional_part

iterates over fractional part. Each iteration returns same results as divide_integer_part escape last numerator_position. Reminder argument for this function must be taken from last divide_integer_part iteration.
