Answer:
Explanation:
First of all, we have to define each part of a division.
- Dividend: is the number we are gonna divide.
- Divisor: is the number that divides the dividend.
- Quotient: is the result of the division.
So, basically, when we divide a certain amount by 2, we just have to find a specific number which allows us to divide the digits of the dividend.
For example, if we wanna divide 286 by 2, we first have to separate the dividend to know if we are going to start dividing one or two digits from the dividend.
We notice that the first digit of the dividend is equal to the divisor, that means we can begin there, in case that the first digit of the dividend is minor than the divisor, we just begin with two digits of the dividend.
So, we choose the first digit of the dividend, which is 2, and now we are gonna use a number in the quotient which product with the divisor results in 2 or near. As you can imagine, we use number 1 in the quotient, because 2(1)=2. Then, the result of the multiplication we subtracted form the digit in the divisor, giving us zero as a result.
Now, we choose the next digit from the dividend, which is 8. Then, we look for a number which product with 2 ends in 8, as you can imagine, that number is 4, because 2(4)=8. Then, we subtract this result from the digit in the dividend giving zero as the difference.
At last, we choose the last number of the dividend, which is 6, then we look for a number which product with 2 ends in 6, and that's 3, because 2(3)=6, then we subtract this from the digit in the dividend, giving zero as result.
At the end, the result of the division is the number formed by all digits place in the quotient. Therefore, the result of the division is 143. So, we can say that 286/2=143
