How to print the result of a SELECT (php / sql) in a specific place in the HTML page?

Greetings,

I have a database with a table of purchase requisitions. In my html there is a panel where the number of purchase requisitions registered will be displayed.

I was able to SELECT right and print the results on a blank page.

But the goal is to print the result inside the request panel that already exists in an HTML page.

How to do this? 

<!DOCTYPE html>
<html lang="pt-br">
  <head>
    <meta charset="UTF-8">
    <link rel="stylesheet" href="_css/estilo.css"/>
    <title>MPparts - seu mercado de peças</title>
  </head>

  <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script><scriptsrc="jquery.big-slide.js"></script>
  <script>
    $(document).ready(function() {
      $('.menu-link').bigSlide();
    });
  </script>

It's very simple, you put the query to the database on the page (I decided to put it in head ) and inside the td you want to show the lines, put the result (This result can be better formatted, as you posted), follow the code: 

<!DOCTYPE html>
<html lang="pt-br">
  <head>
    <meta charset="UTF-8">
    <link rel="stylesheet" href="_css/estilo.css"/>
    <title>MPparts - seu mercado de peças</title>

    <?php
        include ('conexao.php');

        $listarequisicoes=mysqli_query($conexao,"select id_requisicao, 
        count(id_requisicao) from tb_requisicoes group by id_requisicao having 
        count(id_requisicao)>0 ") or die("erro");//lista todas as requisicoes cadastradas no banco de dados
        $linhas= mysqli_num_rows($listarequisicoes);//conta requisicoes
    ?>

      </head>

      <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script><scriptsrc="jquery.big-slide.js"></script>
      <script>

In PHP 

if ($linhas==''){

    $texto = 'Requisições<br>nenhum registro';
}
else{

     $texto = 'Requisições<br>'.$linhas;
}

HTML

  

Within JavaScript include this line 

$("#painel_requisicoes").html('<?php echo $texto ?>');
