regex - Find & Replace digit by digit and space in Sublime Text -

i have lot of digits , want add together spaces in between them, so:

0123456789 --> 0 1 2 3 4 5 6 7 8 9

i'm trying using search , replace function in sublime text. i've tried far using \s find characters (there digits doesn't matter) , \1\s replace them. however, deletes digits , replaces them s. know how this?

press ctrl + h open search , replace dialog (make sure click .* @ left enable regular look mode):

search for: (\d)(?!$) replace with: $1[space]

the regular look (\d)(?!$) matches digits except 1 @ end of line.

here's how looks like:
