To divide successfully it needs to have enough of a crown to split, ie stems coming from below ground level over a reasonable area, maybe something like 6 inch diameter or more, not all from one point.
There's a video of someone dividing S. Caradonna here https://www.youtube.com/watch?v=8CWqW4RGLBU , although I think his is maybe a bit on the small side to be divided. Maybe I'm being over-cautious.
Doncaster, South Yorkshire. Soil type: sandy, well-drained
I agree that when they're young plants, cuttings is the way to go. After about 3 years my S. Mainacht (perennial type) had formed a small clump that were easily split apart and panted here and there. If you remove the flower spike as it starts to go over, I find they flower for months.

Knowledge is knowing that a tomato is a fruit. Wisdom is not putting it in a fruit salad.
