Find / Replace

[beginner]

I need help for Find / Replace in Word
I need to replace the dot-dot distance (dot-blank).
The problem is that there are numbers that contain the dot.



example:
This planet is called Earth.It contains the continents that have 125,254,564.15 m2

solve:
This planet is called Earth. It contains the continents that have 125,254,564.15 m2
So, I need to disassemble the two letters but not allowed between numbers
