Placing post content within nested divs?

I’d like to lay out my page as follows:

<div1>
</div>
<div2>
<div3>
</div>
<div4>
template navigation
</div>
</div>

Ideally the div structure would be included in the post but the template navigation is included by the template, is that possible?

Obviously I could include the navigation from the template in each post but that seems a little redundant
