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.
fid = fopen('s1.csv','wt+');
if fid>0
V = S{1};
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.
