PHP and Wordpress - Place content in correct colum

I have a FAQ page. Consisiting of questions. The order of the questions does not matter. What matters is the layout. Its a three column layout.

When you only have 3 questions, the layout is correct. It looks like this.

[question Z] [question A] [question O]

The problem:
When you have 4 questions the layout looks like this.

[question Z] [question A]
[question X] [question O]

It should look like this.

[question Z] [question A] [question O]
[question X]

Its a 3 column layout. I would like the questions to fill out the fist row. Than start with the second.

I need to do this, without chaning the Bootstrap grid.

The gird was set up in such a way, that when the user clicks read more on a question, only the column expand and not the row.

<?php if ( $wp_query->have_posts() ) : ?>
    <?php 
        $counter=0;
        $total_posts = $wp_query->post_count;
        $posts_per_column = ceil($total_posts / 3);
    ?>


<section class="faq content">
<div class="container-fluid">
  <div class="container-wrapper-faq">
    <div class="row">
    <div class="col-lg-4">
      <div class="col-lg-12">
            <?php while ( $wp_query->have_posts() ) : $wp_query->the_post(); $counter++; ?>                 
          <div class="faq-all">
            <div class="faq-item">
              <h2><?php the_title(); ?></h2>
              <article>
                <div class="faq-intro">
                   <?php the_content(); ?>
                </div>
                <div class="faq-info">
                   <?php the_content(); ?>
                </div>   
                <div class="faq-link">
                  <a href="#" class="read-more">LES HELE SVARET</a>
                  <a href="#" class="read-less">LES MINDRE</a>
              </div>
             </article>
            </div>
          </div> 
            <!-- Close and open div if the "counter" divided by the "posts per column" of columns you want equals zero -->
            <?php if($counter % $posts_per_column == 0) echo '</div></div><div class="col-lg-4"><div class="col-lg-12">'; ?>
            <?php endwhile; ?>
        </div>
    </div>
  </div>
  </div>
</div>

Thanks in advance

So I am sure there is a cleaner way to pull this off but its early and my brain is not functioning at 100%. This should fix your problem. Basically if the total posts = 4,7,10,13... what we had before would always trim it so that it never reached the 3rd column. I added some code that checks to see if it is one of these special cases I just did some basic math and subtracted the total posts by one, then divided that by three, if it is a round number I know its a special case. So I change the posts per column to be one less, then in the loop we check if its the first post and we don't increment the counter.

<?php if ( $wp_query->have_posts() ) :
  $counter=0;
  $columns=3;
  $total_posts = $wp_query->post_count;
  $posts_per_column = ceil($total_posts / 3);
  $posts_per_column_test_value = ($total_posts - 1) / $columns;
  $is_special_case = false;
    if($total_posts != 1 && (intval($posts_per_column_test_value) == $posts_per_column_test_value)){
        $is_special_case = true;
        $posts_per_column = $posts_per_column - 1;
    }
?>
