If you tried to equally divide an unequal amount of candies, you would be left with a few remaining candies. In division, those that remain are called remainders.
What do we do with this remainder? Do we display the number as a floating point or do we round it down to the closest whole number?
Python has an answer with its division operators.
Types of division operators in Python
In Python, there are two types of division operators:
/: Divides the number on its left by the number on its right and returns a floating point value.
//: Divides the number on its left by the number on its right, rounds down the answer, and returns a whole number.
The illustration below shows how this works.
Examples
Now that we know how the operators work and what kind of division each operator performs; let’s look an example of division in Python.
# Dividing an integer by an integer print("The answer for 5/2: ") print(5/2) print("The answer for 5//2: ") print(5//2) print("n") # Dividing an integer by a float print("The answer for 5/2.75: ") print(5/2.75) print("The answer for 5//2.75: ") print(5//2.75) print("n") #Dividing a float by an integer print("The answer for 5.5/2: ") print(5.5/2) print("The answer for 5.5//2: ") print(5.5//2) print("n") #Dividing a float by an float print("The answer for 5.5/2.5: ") print(5.5/2.5) print("The answer for 5.5//2.5: ") print(5.5//2.5)RELATED TAGS

Division Operators allow you to divide two numbers and return a quotient, i.e., the first number or number the left is divided by the second number or number the right and returns the quotient.
There are two types of division operators:
(i) Float division:
The quotient returns by this operator is always a float number, no matter if two numbers are integer. For example:
>>>5/5 1.0 >>>10/2 5.0 >>>-10/2 -5.0 >>>20.0/2 10.0(ii) Integer division( Floor division):
The quotient returned by this operator is dependent on the argument being passed. If any of the numbers is float, it returns output in float. It is also known as Floor division because, if any number is negative, then the output will be floored. For example:
>>>5//5 1 >>>3//2 1 >>>10//3 3Consider the below statements in Python.
Python3
print (5//2)
print (-5//2)
Output:
2 -3The first output is fine, but the second one may be surprised if we are coming Java/C++ world. In Python, the “//” operator works as a floor division for integer and float arguments. However, the division operator ‘/’ returns always a float value.
Note: The “//” operator is used to return the closest integer value which is less than or equal to a specified expression or value. So from the above code, 5//2 returns 2. You know that 5/2 is 2.5, and the closest integer which is less than or equal is 2[5//2].( it is inverse to the normal maths, in normal maths the value is 3).
Example
Python3
print (5.0/2)
print (-5.0/2)
The real floor division operator is “//”. It returns the floor value for both integer and floating-point arguments.
Python3
print (5//2)
print (-5//2)
print (5.0//2)
print (-5.0//2)
See this for example.

Why is the div operator used?
MySQL div operator is used for integer division. An expression which contains the dividend.How do you divide 2 in Python?
Integer division takes two numbers and divides them to give a result of a whole number. In Python 3, integer division (or floor division) uses the double front-slash // operator. In Python 2, integer division uses the single front-slash / operator.How do you divide a number in Python?
Python program to divide numbers user input To take the inputs from the user. The result=number1/number2 is used to divide the two numbers.Why do we use division to float in Python?
Behavior of the division operator in Python 2.7 and Python 3 // is not "used for integer output". // is the result of the floor() function to the result of the division, which in turns yields an integer if the two operands are integers and a float if least one of them is a float, for types coherence.
