title: Remove last digits from an int
body: <p>Can't seem to find a good answer to this question. How do I remove the last 11 digits from an int?</p>
  
  <p>The id could be one or more numbers in the beginning but there will always be 11 digits following the id. There will always be an id in the beginning. <code>{id}{11 digits}</code>.</p>
  
  <pre><code>var getId = function (digits) {
     // Do some stuff and return id
  }
  
  getId(110000000001); // Should return 1
  getId(1110000000001); // Should return 11
  getId(2010000000001); // Should return 20
  </code></pre>
