Returning to our example of multiplying 54.321 by 0.06, we used 54 321 instead of 54.321,
which meant that the number that was 1000 times bigger than the given number, which
consequently made the answer 1000 times too big. Further, we continued by using 6 instead
of 0.06, a number 100 times bigger than was given, thus making the result yet another 100
times bigger. To bring the result back to what it should have been, we must divide the
number 325 926 by 1000 and again by 100 – or doing it in one go, dividing by 100 000
(1000 ´ 100).
Referring back to our rule, dividing by 100 000 (5 zeros) is the same as moving the point 5
places from the right (remember this 5 came from the 3 digits to the right of the decimal
point in 54.321 which were initially ignored and the 2 digits to the right of the decimal point
in 0.06).
