Th e calculation begins as usual.
Th ree divides once into 5 with 2 remainder. We carry the 2 remainder
to the next digit, making 26. We write the answer, 1, below (or
above) the 5 we divided. Th e calculation looks like this:
1
3 5^2 67.8
We now divide 26 by 3. Eight times 3 is 24, so the next digit of the
answer is 8, with 2 remainder. We carry the 2 to the 7.
1 8
3 5^262 7.8
Th ree divides into 27 exactly 9 times (9 × 3 = 27), so the next digit
of the answer is 9.
1 8 9
3 5^262 7.8
Because the decimal point follows the 7 in the number we are
dividing, it will follow the digit in the answer above the 7.
We continue as before. Th ree divides into 8 two times with 2
remainder. Two is the next digit of the answer. We carry the
remainder, 2, to the next digit.
1 8 9.2
3 5^262 7.8^2
Because there is no next digit, we must supply a digit ourselves.
We can write a whole string of zeros after the last digit following a
decimal point without changing the number.
We will calculate our answer to two decimal places, so we must make
another division to see how we round off our answer. We write two
more zeros to make three digits after the decimal.
