In this article, we will learn about python program to divide two numbers using recursion with examples.

Getting Started

The task is to divide two numbers using recursion. For example,

If a = 9 and b = 3, then output is 9 / 3 = 3. But, we need to do it using recursion.

We can do so in multiple ways –

• Simple Approach
• Using User Input

Simple Approach

• Take static input of two numbers.
• Write function that takes two arguments x and y.
• Inside that function, return 0 if x is less than y. Otherwise, subtract y from x each time function is called.
• In each function call, we are adding 1 to return value.
• Basically, we are keep track of how many times y is subtracted from x so that x becomes less than y.

 
def divide(x, y):
    if(x < y):
        return 0
    else:
        return 1 + divide(x - y, y)


x = 658
y = 60

result = divide(x, y)
print("Result:", result)

Output:

 
Result: 10

Result is printed using print() function in python.

Using User Input

• Take input from user using input() function. Then, convert them to integer using int() function.
• Write function that takes two arguments x and y.
• Inside that function, return 0 if x is less than y. Otherwise, subtract y from x each time function is called.
• In each function call, we are adding 1 to return value.
• Basically, we are keep track of how many times y is subtracted from x so that x becomes less than y.

 
def divide(x, y):
    if(x < y):
        return 0
    else:
        return 1 + divide(x - y, y)


x = int(input("Enter a number"))
y = int(input("Enter another number"))

result = divide(x, y)
print("Result:", result)

Output:

 
Enter a number
500
Enter another number
50
Result: 10

Result is printed using print() function in python.

That’s how we can write python program to divide two numbers using recursion with examples.
