title: JQuery: replace a string inside a div
body: <pre><code>&lt;div id="content"&gt;
  ...
  &lt;p&gt;NUMBER times...&lt;/p&gt;
  ...
  &lt;p&gt;Place N°: NUMBER&lt;/p&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>How do I replace all NUMBER inside the content div?
  I tried <code>replace</code> method but it didn't work.</p>
  
  <p>Thanks.</p>
