Sure, I can help you with that. Here are the steps to split the text into multiple columns using a common delimiter:

1. Select the column that contains the data you want to split (in this case, column A).
2. Click on the "Data" tab in the ribbon at the top of the screen.
3. Click on the "Text to Columns" button in the "Data Tools" group.
4. In the "Convert Text to Columns Wizard" that appears, select "Delimited" and click "Next".
5. In the next screen, select the delimiter that separates the data in your column (in this case, the asterisk "*") and click "Next".
6. In the next screen, you can choose the format of the columns you want to create. For this example, select "General" for both columns B and C and click "Finish".
7. Your data should now be split into two columns, with the data preceding the "*" in column B and the data following the "*" in column C.

That's it! Your data should now be split into two columns based on the common delimiter.
