# JavaScript- How to check if a number divides in another number without a quotient?

Use the modulus operator (%), which gives the remainder. For example, 20%5 == 0, because 20/5 is 4 remainder 0, but 18%5 == 3 because 18/5 is 3 remainder 3.

Hello fellows,

I recently started learning JavaScript, after understanding HTML and CSS.

I am trying to code a program (with JS) that will calculate the sum of all numbers between 1-100 that divide in 5 or 7 without a reminder, using variables and for loop.

I think I can figure out how to code everything except one thing- how to check if a number divides in another number without a reminder?

I hope I explained myself well.

Thank you!

*I got confused in the headline, I meant "reminder" instead of "quotient". My intention is how to check if a number divides in another number and the result is an integer.

Programming is a branch of mathematics.

Thank you very much for the quick respondence! You helped a lot and I managed to code the program I wanted.
