document.querySelector('div[contenteditable="true"]').addEventListener("paste", function(e) {
        e.preventDefault();
        var text = e.clipboardData.getData("text/plain");
        document.execCommand("insertHTML", false, text);
    });

It is simple: add a listener to the "paste" event and reeformat clipboard contents.

Here another example for all containers in the body:

[].forEach.call(document.querySelectorAll('div[contenteditable="true"]'), function (el) {
    el.addEventListener('paste', function(e) {
        e.preventDefault();
        var text = e.clipboardData.getData("text/plain");
        document.execCommand("insertHTML", false, text);
    }, false);
});

Saludos.

Have you tried using innerText?

ADDED:

If you want to strip markup from content pasted into the editable div, try the old hack of creating a temporary div -- see example below.

<!DOCTYPE html>
<html>

<head> 
  <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> 
  <title>Strip editable div markup</title>

  <script type="text/javascript">
    function strip(html) {
      var tempDiv = document.createElement("DIV");
      tempDiv.innerHTML = html;
      return tempDiv.innerText;
    }
  </script>
</head>

<body>
  <div id="editableDiv" contentEditable="true"></div>
  <input type="button" value="press" onclick="alert(strip(document.getElementById('editableDiv').innerText));" />
</body>

</html>
