Long String of text and need to insert space every 8th character

Hello all,

I have a long string of text in A1. Looks something like this:

DTLA9494DTLA9494DTLA9494DTLA9494DTLA9494DTLA9558DTLA9433DTLA9450DTLA9457DTLA9491DTLA9324DTLA9491DTLA9074DTLA9074DTLA9073DTLA4912

That continues on thousands of characters long...

I would like to insert spaces every 8th character. Alternatively it could be a space in front of DTLA if there is a function that is easier. The data is consistant and DTLA#### repeats numerous times and does not change if that makes sense. I do not know exactly how many characters in total the string is but more than likely it is DTLA#### repeated at least 400 to 500 times.

Any help is greatly appreciated!
