Floor division

The problem

Find the floor division of two numbers.

Hints

Floor division means the integer part of a division operation. For example, if you divide 17/5 the quotient will be 3.4.

Here the integer part is 3.

So, you have to find the integer part of the division operation.

Solution

num1 = int(input('Enter the first number: '))
num2 = int(input('Enter the second number: '))
 
result = num1//num2
print(result)

Explanation

When you divide one number by another you get two things. One is called the integer part of the division. Another is the remainder.

To get the quotient (result without the remainder), you can use two-division symbols.

print(37//10)
37 = 3*10+7

Think different

Another alternative approach is to use the floor method from the math module. If you pass a number with a fraction to the math.floor function, it will return you the integer part of the number.

For example,

import math
result = math.floor(3.4)
print(result)

Alternative Solution

Now, you can use the floor function to get the floor the division. Like below-

import math
num1 = int(input('Enter the first number: '))
num2 = int(input('Enter the second number: '))
 
result = math.floor(num1/num2)
print(result)
