Remember that your strings are just arrays of characters. So when you export the array to file using csvwrite, a comma will be inserted between each element in the array - so a comma between each character.

You may want to consider an alternative method to export cell array data to a text file. From this example, you could do

 % open the file
 fid = fopen('s1.csv','wt+');
 if fid>0
     % write each row to file
     V = S{1};     % assumes that V is a cell array
     for k=1:size(V,1)
         fprintf(fid,'%s,%s\n',V{k,:});
     end
     fclose(fid);
 end

Now, when you open the s1.csv file, you will see

 4400002970000003533,8500000190000013093
 4400002970000003533,8500000190000045501
 4400002970000003533,8500000840000005660
 4400002970000003533,8500000840000006008

which is probably what you would like.
