Some examples of numbers divisible by 3 are as follows.
The number 85203 is divisible by 3 because the sum of its digits 8+5+2+0+3=18 is divisible by 3..
How do you do division with 2 digit divisors?
Divide the first number of the dividend (or the two first numbers if the previous step took another digit) by the first digit of the divisor. Write the result of this division in the space of the quotient. Multiply the digit of the quotient by the divisor, write the result beneath the dividend and subtract it.

How do you explain short division?
Short divisionShort division will sometimes give an answer with a remainder (r), which you can round up or round down.To find the answer to 365 ÷ 7 see if 3 (the hundreds) can be divided by 7.It cannot, so add the tens digit. … Write down the 5 and carry over the 1 so 5 becomes 15.15 ÷ 7 = 2 r 1.Write those numbers down.
How do you check if a number is multiple of 3?
There is a pattern in binary representation of the number that can be used to find if number is a multiple of 3. If difference between count of odd set bits (Bits set at odd positions) and even set bits is multiple of 3 then is the number. 1) Get count of all set bits at odd positions (For 23 it’s 3).
How do you divide triple digits?
Let’s start and divide by 3 digit numbers!How many digits are there in the divisor? 3!We take the same number of digits in the dividend.We compare the 3 digits in the dividend with the 3 digits in the divisor. … We divide the first digits of the dividend and the divisor. … We bring down the next digit of the dividend.
