title: Split a string every 5 characters
body: <p>Suppose I have a long string:</p>
  
  <pre><code>"XOVEWVJIEWNIGOIWENVOIWEWVWEW"
  </code></pre>
  
  <p>How do I split this to get every 5  characters followed by a space?</p>
  
  <pre><code>"XOVEW VJIEW NIGOI WENVO IWEWV WEW"
  </code></pre>
  
  <p>Note that the last one is shorter.</p>
  
  <p>I can do a loop where I constantly count and build a new string character by character but surely there must be something better no?</p>
