I would like to know how I can make the sum but eliminate or disregard the "R $", turning it into a number.

The values in R $ are generated automatically by the system.

Follow the code:

<html><head>
<script type="text/javascript">
window.onload = function (){
  document.querySelector('div.de').id = 'de';
  document.querySelector('div.por').id = 'por';
  document.querySelector('div.economize').id = 'economize';
  var Div = document.createElement("div");
  document.body.appendChild(Div) ;
  Div.id = 'resultado';
  var Campo1 = document.getElementById("de")  .innerHTML  ;
  var Campo2 = document.getElementById("por")  .innerHTML  ;
  var Campo3 = document.getElementById("economize")  .innerHTML  ;
  var subtracao = eval(parseInt(Campo3) / parseInt(Campo1) * 100);
  document.getElementById('resultado').innerHTML  = subtracao.toFixed(1)+"%"  ;
}
</script>
</head>
<body>
<div class="de"> R$ 266,00  </div>
<div class="por"> R$ 145,36</div>
<div class="economize"> R$  120,64</div>

</body></html>

You can use replace, like this:

var Campo1 = document.getElementById("de").innerHTML.replace('R$', '').replace(',','.');
var Campo2 = document.getElementById("por").innerHTML.replace('R$', '').replace(',','.');
var Campo3 = document.getElementById("economize").innerHTML.replace('R$', '').replace(',','.');
