Split results into 5 columns

I have a query like:

$results = Post::all();

For the sake of simplicity, let's say the output is this (by id):

1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15

My website has a 5-column layout. I need to split/divide these results into 5 columns such that it ends up like this:

 1 |  2 |  3 |  4 |  5
 6 |  7 |  8 |  9 | 10
11 | 12 | 13 | 14 | 15

The 5 column layout is split like this (the total number of columns is 25):

<div class="row">
    <div class="col-xs-5">
        //
    </div> 
    <div class="col-xs-5">
        //
    </div> 
    <div class="col-xs-5">
        //
    </div> 
    <div class="col-xs-5">
        //
    </div> 
    <div class="col-xs-5">
        //
    </div> 
</div>

How can I split $results up like this? Any way to make use of Laravel's Collection methods?
