The only 'stupid questions' are the ones that don't get asked.
That said, you may be knocking on the wrong door to ask this one. You've posted in the Numbers community, where the topic is the Mac version of Numbers. I can give you the Mac answer, but the iOS answer likely involves a tap in place of the command-F keystroke, so I'll also put in a request to have your post transferred to the iWork for iOS community.
In Numbers or Pages on the Mac, press command-F to open the Find dialogue.
Enter the text into the box, then click Find.
There are some variations on this, but they're explained pretty well on the screen.
