• if 280 divided by 5 what is 2800 divided by 5
• Just add a zero to the end of the answer to 280/5 (the '/' means divide).
• thank you but I still dont get long division
• If you understand this, you understand place value.
Q)3618/9
Correct: 3618/9 = 402 because
(3600+18)/9 = 3600/9 + 18/9 =400+2 = 402.
Wrong: 3618/9 = 42 because 36/9 = 4 and 18/9 =2.
If you multiply 42*9 we get 288.
If you multiply 402*9 =3618

When in confusion, distribute the number in to parts that are divisible by the divisor.
In this example we distributed the parts which are divisible by 9.
