title: Split numerical values and find unique numbers
body: <p>I have a data set where column A looks like this:</p>
  
  <pre><code>80419, 80038, 9306
  7742
  10638
  10638
  10694, 7738
  8958, 7741
  7706, 8537
  7747, 8954
  7747, 8954
  7742
  9907, 80465
  10638
  7747, 8954
  7706, 8537
  80040, 80043
  80040, 80043
  7747, 8954
  80040, 80043
  80040, 80043
  80043
  80043
  80040, 80043
  80040, 80043
  80040, 80043
  80040, 80043
  80040, 80043
  </code></pre>
  
  <p>Ultimately, I would like to pull the unique values from this data set. </p>
  
  <p>I have tried to split these values first but I am running into an issue where '80040' becomes 8004. I need to retain 0's on the ends of the values. </p>
