Modulus Calculator: Quick, Simple, and Reliable

Need a fast way to get remainders? This modulus calculator keeps the math clear. Enter your numbers and press Calculate. You will see the result line, a full long division view, and a programming expression. Use Copy Result to grab the line for pasting.

What Is a Modulus Calculator?

A modulus calculator finds the remainder after division. It works with a dividend and a divisor. The result is called the modulus or mod. The tool supports integers and decimals. With a positive divisor the remainder stays between zero and the divisor value.

How It Works

Step-by-Step Instructions

1. Enter the dividend in the field labeled Dividend.
2. Enter the divisor in the field labeled Divisor.
3. Press Calculate to run the math.
4. Press Enter to run the same action from your keyboard.
5. Select Copy Result to copy the main result line.

The result appears below the button. You will see three parts. The main line shows dividend mod divisor equals the remainder. The long division area shows the quotient and remainder. It also states dividend equals divisor times quotient plus remainder. The programming expression shows dividend percent divisor equals remainder. Example, 24 mod 7 equals 3.

Why You'll Love This Modulus Calculator

Simplicity at Its Best

The layout stays clean and direct. You get the remainder, the long division breakdown, and a programming style line. Results arrive fast with clear labels. The steps stay the same for every case.

Built for Everyone

This modulus calculator helps students, engineers, and developers. It fits quick checks and repeat tasks.

• Check odd or even using number mod 2.
• Wrap hours on a 24 hour clock.
• Cycle through list indexes in code.
• Split items into fixed size groups.
• Compute a day offset from a start day.
• Work with checksums used to catch errors.

Extra Tips

Use numbers only, whole or decimal. Use a nonzero divisor. Use a positive divisor for a standard remainder range. Negative inputs work with a positive divisor, the remainder stays between zero and the divisor value. Decimal inputs return a fractional remainder. Many languages write the operation with the percent sign. Some languages treat negatives in different ways, check your language rules. Very large integers above 9007199254740991 may lose precision. For exact integer math stay within the safe range.

Final Thoughts

This modulus calculator gives clear results in seconds. You get the remainder, a long division proof, and a programming expression you can copy. Keep it handy for math, code, and quick checks.
