There's a lot of interesting arguments that once you get into big numbers you should do big rationals instead of just big decimal division. You can easily include big rationals in an article like this because it just holding two big numbers together (a numerator and a denominator), but the jump to reasoning with rational notation can be a surprising challenge and there's forever the temptation of still wanting to get decimals back out (so you can't entirely ignore decimal division) because most of us don't like to use rational notation/fractions regularly.
