This issue occurs when you try to divide a number by zero. Because divide any number by zero is undefined.

Here $show_enter has 0 value. That's the problem. I don't know where $show_enter is coming from, So you need to debug $show_enter.

But in your system Is there any possibilities $show_enter to have 0 value, Then you need to fix this calculation issue by using condition.

<ul class="list list-icons list-icons-style-3 list-primary">
    <li><i class="fa fa-calculator"></i> <strong>Entries:</strong> <?php echo $show_enter; ?> -  <strong>Attended:</strong> <?php echo $show_attended; ?> -  <strong>Percent Turnout:</strong> 
    <?php
    if(!empty($show_enter)){
        echo round_out(($show_attended/$show_enter)*100) . '%';
    }else{
        echo '%';
    }
    ?></li>
</ul>
