geocordinates issue in excel

Hello, guys!

I got a database with approx. 50,000 locations and geo-coordinates. However, I found out that these geo-coordinates are written in a wrong form... Not all of the, but some.
For example, a location with latitude 451.833 and longitude 0.7167 should look like 45.1833 and 0.7167
What is more, the format of a number is not as decimal, but as thousands...

Any ideas? Could it be a solution to use "Find/Replace"?

If you post a workbook with samples someone will figure it out pretty soon.
