You need to tell Python to use floating point values  not integers  You can do that simply by using a decimal point yourself in the inputs    gt  gt  gt  4 100 0 0 040000000000000001

Other answers suggest how to get a floating-point value   While this wlil be close to what you want  it won t be exact    gt  gt  gt  0 4 100  0 0040000000000000001   If you actually want a decimal value  do this    gt  gt  gt  import decimal  gt  gt  gt  decimal Decimal  4     decimal Decimal  100   Decimal  0 04     That will give you an object that properly knows that 4   100 in base 10 is  0 04    Floating-point numbers are actually in base 2  i e  binary  not decimal

Add the following function in your code with its callback     Starting of the function def divide number one  number two  decimal place   4       quotient   number one number two     remainder   number one   number two     if remainder    0          quotient str   str quotient          for loop in range 0  decimal place               if loop    0                  quotient str                    surplus quotient    remainder   10    number two             quotient str    str surplus quotient              remainder    remainder   10    number two             if remainder    0                  break         return float quotient str      else          return quotient  Ending of the function    Calling back the above function   Structure   divide  lt divident gt    lt divisor gt    lt decimal place optional  gt   divide 1  7  10    Output   0 1428571428   OR divide 1  7    Output   0 1428   This function works on the basis of  Euclid Division Algorithm   This function is very useful if you don t want to import any external header files in your project   Syntex   divide  divident    divisor    decimal place optional    Code   divide 1  7  10  OR divide 1  7   Comment below for any queries

Try 4 0 100

User · Answer

Make one or both of the terms a floating point number  like so   4 0 100 0   Alternatively  turn on the feature that will be default in Python 3 0   true division   that does what you want  At the top of your module or script  do   from   future   import division

You might want to look at Python s decimal package  also   This will provide nice decimal results    gt  gt  gt  decimal Decimal  4   100 Decimal  0 04

There are three options    gt  gt  gt  4   float 100  0 04  gt  gt  gt  4   100 0 0 04   which is the same behavior as the C  C    Java etc  or    gt  gt  gt  from   future   import division  gt  gt  gt  4   100 0 04   You can also activate this behavior by passing the argument -Qnew to the Python interpreter     python -Qnew  gt  gt  gt  4   100 0 04   The second option will be the default in Python 3 0  If you want to have the old integer division  you have to use the    operator    Edit  added section about -Qnew  thanks to   O
