This is not possible without more information. Say you do this:

S=strrep('3 9 8 . 6 1 9 5 0 0 1 3 0 3 1 3 . 2 1 2 7 6 0',' ','')
% S='398.619500130313.212760'

Should the second number be 313.212760 or 130313.212760 or 3.212760 or any of the other several or so combinations? You need to provide more information to be able to decipher the numbers.
