We look at the division of 86809 by 3 
Our goal is to divide 86809 by 3.

Going ahead to step 1:
When dividing 8 by 3, we get 2 with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 6 from 8 and we're left with 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 3

Going ahead to step 2:
3 can be fit into 26 8 times, resulting in a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 28.0
If we subtract 24 from 26, we get 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 3

Moving on to step 3:
When dividing 28 by 3, we get 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 289.0
If we take 27 away from 28, we end up with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 3

Going ahead to step 4:
When dividing 10 by 3, we get 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 2893.0
Subtracting 9 from 10 leaves us with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 3

Advancing to step 5:
If we divide 19 by 3, we get 6 and a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 28936.0
Subtract 18 from 19 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 6:
3 can be fit into 10 3 times, resulting in a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 28936.3
Deduct 9 from 10 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
3 can be fit into 10 3 times, resulting in a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 28936.33
Subtracting 9 from 10 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The quotient of the division is 28936.33, and the remainder is 0.001.
