Group form fields in Symfony2

I want to group fields in symfony2. For example wrap them in a div and place headlines in between:

<form>
<div class="step-1">
    <h3>Step 1</h3>
    Field 1
    Field 2
</div>
<div class="step-2">
    <h3>Step 2</h3>
    Field 3
    Field 4
</div>
</form>

The problem is the form got very much fields so i cant render them one by one in the template. Isnt there any option when adding fields? Like:

$form = $this->createFormBuilder()
        ->addGroup('step-1')

Or how can i handle this?
