How to divide rows in calc

I am new to the LibreOffice programs. I have been trying to divide row 2 by row 3 for 20 minutes now, I could really use some help.

Did you ever throw a glance at any text on spreadsheets? Seen any examples? That’s simply necessary.
The ‘Calc Guide’ available here should help. Don’t worry much about the version. The basics didn’t change.

Somewhere in the A column (wherever you want the result to be), enter =A2/A3 and copy that formula to the rest of the row.
