It looks like you're trying to express a mathematical equation, but the formatting is a bit unclear. If you're trying to show a division problem and resulting equation, could you clarify what you mean with the numbers? For example, if you want to divide 51 by 5, it would look like this:
\[ 51 \div 5 = 10.2 \]
If you're trying to show something else, please provide additional context, and I'd be happy to assist!
