Yes, it is possible to set up the pivot table to display the division of 2 cells of data in the same row. Here are the steps to add the % Shipped column to your pivot table:

1. Select the pivot table and go to the "PivotTable Analyze" or "Options" tab in the ribbon.
2. Click on "Fields, Items & Sets" and select "Calculated Field".
3. In the "Name" field, enter "% Shipped" or any other name you prefer.
4. In the "Formula" field, enter "= Sales Shipped / Sales Ordered".
5. Click "Add" and then "OK".
6. The new calculated field will be added to the pivot table as a new column.

Now you should see the % Shipped column in your pivot table, which displays the division of Sales Shipped by Sales Ordered for each salesperson. The % Shipped column will automatically update as you make changes to the pivot table.
