title: How to divide a number of columns by one column?
body: <p>I have the below dataset:</p>
  <pre><code>Monday Tuesday Wednesday Friday Saturday Total
  2       3      4          5      6        20
  3       6      7          5      1        22
  </code></pre>
  <p>I am doing the below:</p>
  <p>I need to divide first row: <code>2/20, 3/20, 4/20, 5/20, 6/20</code></p>
  <p>And on the second row: <code>3/22, 6/22, 7/22, 5/22, 1/22</code>.</p>
  <p>I can do this by extracting the columns but it is long and tedious, there must be an easier way.</p>
