<div class="example">Some example text</div>
<div class="example">Some more example text</div>

$('div').each(function() {
    this.innerHTML= this.innerHTML.replace(/e/g, '');
});

If you want e or E use this:

$('div').each(function() {
    this.innerHTML= this.innerHTML.replace(/e|E/g, '');
});

If there are elements inside those <div>s use the text function to get only the textNodes:

$('div').each(function() {
    $this = $(this);
    $this.text($this.text().replace(/e|E/g, ''));
});
