Dividing perennial dianthus

hi, I have had a carnation for about 6 years, don’t know the variety but it’s a thick grey carpet of foliage and a pink flower (sort of a blue pink) all the same on a medium stem. 
I was going to divide this now, it’s quite large, but on investigation, the foliage is sort of sat on the ground, I can’t see anything actually rooted, up to a few inches in. You can lift it up off the ground. 
Can I take these bits off, will they root somehow? or do I need to dig the whole thing up, and then do you effectively lose the bits round the outside not rooted?

    I'm pretty sure dianthus are single-stemmed, so can't be split.  I have one which has spread to cover over a square metre but it's just a mat laying on the surface and all coming from a single woody stem.  As above, cuttings of non-flowering shoots is the way to propagate them and is pretty easy. :)
    A trowel in the hand is worth a thousand lost under a bush.

    lazy cuttings works well, bury the stems in very gritty mix and they will root into it

    Ah mine sounds just like that Bob. OK I will give cuttings a go. It’s a shame I thought a sharp spade would do the job! Thanks all.
