Result so far: 2.0
If we subtract 6 from 8, we get 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 3

Advancing to step 2:
23 divided by 3 is 7 with a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 27.0
Deduct 21 from 23 and we're left with 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 3

Moving on to step 3:
3 goes into 26 8 times with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 278.0
The remainder is 2 after subtracting 24 from 26.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 3

On to step 4:
The number 3 fits into 21 7 times, leaving a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 2787.0
Deduct 21 from 21 and we're left with 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 3

Going ahead to step 5:
4 divided by 3 is 1 with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 27871.0
Deduct 3 from 4 and we're left with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 3

On to step 6:
10 divided by 3 is 3 with a remainder of 1.
The next digit of our result is 3. 
Result so far: 278713.0
If we subtract 9 from 10, we 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 7:
3 goes into 10 3 times with a remainder of 1.
The next digit of our result is 3. 
Result so far: 278713.3
If we take 9 away from 10, we end up 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 8:
3 can be fit into 10 3 times, resulting in a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 278713.33
If we take 9 away from 10, we end up 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.

Our division results in 278713.33 with a remaining 0.001.
