Ruby program to find the remainder without using the modulus (%) operator

Last Updated : December 15, 2025

Problem Solution

In this program, we will read two integer numbers from the user and then find the remainder without using the modulus "%" operator and print the result.

Program/Source Code

The source code to find the remainder without using the modulus "%" operator is given below. The given program is compiled and executed successfully.

# Ruby program to find the remainder 
# without using modulus (%) operator

num1=0
num2=0
rem=0

print "Enter number1: ";
num1 = gets.chomp.to_i;  

print "Enter number2: ";
num2 = gets.chomp.to_i;  

rem=num1-(num1/num2)*num2;

print "Remainder is: ",rem;

Output

Enter number1: 8
Enter number2: 3
Subtraction is: 5

Explanation

In the above program, we created three variables num1, num2, rem initialized with 0. Then we read values num1 and num2 from the user. After that, we found the remainder without using the modulus (%) operator and printed the result.
