How to do lond division 0.6÷0.0024
Kryger [21]
So...notice first off, the 0.6 has 1 decimal, the 0.0024 has 4 decimals

what happens is, the dot goes poof BUT, you need to add as many zeros to each number as the other's decimals.

the 0.6 has one decimal, so 0.0024 gets an added zero and loses the dot, to become 000240.

the 0.0024 has four decimals, thus the 0.6 gets added 4 zeros then, and loses the dot, to become 060000

and then you divided that, those are the dividend and divisor.
