Am I reading that right? Do you have a 10 GiB swap? :-?

So, you have 2 logical partitions: sda5 (3 GiB) and sda6 (225 GiB) and I 
guess you want to "split/resize" sda6 into smaller ones (sda7, sda8...). 
You can do it with "gparted" (or cfdisk) but:

1/ Make a copy of the data on it (if any) before making any change.

2/ You have to work offline, the volume you are splitting cannot be 
mounted. You can manually unmount it or just use a Live medium and make 
the partitions from there.
