In the case of a sum of money (in this country) it's just as quick to say "two hundred and nineteen pounds forty-four".
I've seen/heard that being used in BE. Just for the record, the same structure isn't used in AE with dollars. We'd have to say (or, we say) "...nineteen dollars forty.-four cents." For whatever reason.
Nine billion, eight hundred and seventy-six million, five hundred and forty-three thousand, two hundred and nineteen point four four would be more natural in present day British English.
I, too, would tend to favor commas separating the major divisions (as they do when such figures are written using the numbers). However, the CMOS online Q&A section indicates a preference to not using them since they could lead one to think that this is a list of four different numbers, Interesting view of things, but I'm not sure that I'm convinced. (CMOS itself apparently gives no guidance on how to write such large numbers out.)
