title: check number is multiple of another
body: <p>I am using Use the remainder operator for number is multiple of another . If first number is 3 and second number is 15 then</p>
  
  <pre><code>if (3 % 15 == 0) {
  
  }
  </code></pre>
  
  <p>then it works (Does not go into if). But now if first number is 3 and second number is 4000 then it not works condition is still true</p>
  
  <pre><code>if (3 % 4000 == 0) {
  
  }
  </code></pre>
  
  <p>here it should not go into if case. but here condition is true. Why is it so?</p>
