the bus stop method or chunking both of them are very acurate methods. chunking, eg.if you were doing 21 divided by 3 you would see what time three is 21. with big numbers you can take away small chunks. eg 336dived by 8 10x8=80 see what you are left with then keep on doing it until you get to 0.add up what you have times it by each ti me and you have your anser
To calculate 336 ÷ 8 , break it down by expressing 336 as 320 + 16 , then divide each part separately. This gives 320 ÷ 8 = 40 and 16 ÷ 8 = 2 , adding up to 42 . Using this strategy allows for easier and more flexible calculations.
