# Division without using ‘/’ operator in C++ Program

C++Server Side ProgrammingProgramming

In this tutorial, we are going to learn how to divide a number without using the division (/) operator.

We have given two numbers, the program should return the quotient of the division operation.

We are going to use the subtraction (-) operator for the division.

Let's see the steps to solve the problem.

• Initialize the dividend and divisor.

• If the number is zero, then return 0.

• Store whether the result will be negative or not by checking the signs of dividend and divisor.

• Initialize a count to 0.

• Write a loop that runs until the number one is greater than or equals to the number two.

• Subtract the number two from the number one and assign the result to the number one

• Increment the counter.

• Print the counter.

## Example

Let's see the code.

Live Demo

#include <bits/stdc++.h>
using namespace std;
int division(int num_one, int num_two) {
if (num_one == 0) {
return 0;
}
if (num_two == 0) {
return INT_MAX;
}
bool negative_result = false;
if (num_one < 0) {
num_one = -num_one ;
if (num_two < 0) {
num_two = -num_two ;
}
else {
negative_result = true;
}
}
else if (num_two < 0) {
num_two = -num_two;
negative_result = true;
}
int quotient = 0;
while (num_one >= num_two) {
num_one = num_one - num_two;
quotient++;
}
if (negative_result) {
quotient = -quotient;
}
return quotient;
}
int main() {
int num_one = 24, num_two = 5;
cout << division(num_one, num_two) << endl;
return 0;
}

## Output

If you run the above code, then you will get the following result.
