title: Is it possible to divide each column value of a table by each column value of another table in powerbi?
body: <p>I have a table A with these columns: site_name, <strong>monthly_productibility</strong>. I also have a table B with these columns: site_name, <strong>monthly_production</strong>.</p>
  <p>I want to divide the column monthly_productibility (<strong>table A</strong>) by the column monthly_production (<strong>table B</strong>).</p>
  <p>When I try the DIVIDE function (fast measure or DAX function):</p>
  <pre><code>DIVIDE(
      SUM('TABLE_B'[monthly_production]),
      COUNTA('TABLE_A'[monthly_productibility]))
  </code></pre>
  <p><em>The results are just so wrong, I tried different formulas but still doesn't work and I want to merge the tables only if I am obligated to do so (I am more into a generic approach).</em></p>
