Dividing decimals is easy, just divide like usual - and work out the number of decimal places as follows:
The number of decimal places in the answer = number of decimal places in the item being divided - number of decimal places in the dividing number....
e.g. 123.963 (3) / 0.3 (1) = 413.21 (3 - 1 = 2) where decimal places are shown in brackets.

This maths calculation tricks helps you quickly work out hard to divide numbers, such as those with long division. With no effort you will be doing long division with 9, leading on to doing long division with any number under 100 in future (linked) videos.
This would have to be the most easy long division trick.
See my other videos for how to divide the normal way, and how to divide fractions and decimals.
