Append the next digit (6) from the dividend to 8 and continue with: 86 / 306

Advancing to step 2:
The number 306 fits into 86 0 times, leaving a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Grab the next digit (6) from the dividend, add it to 86, then carry on: 866 / 306

Advancing to step 3:
306 can be fit into 866 2 times, resulting in a remainder of 254.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 612 away from 866, we end up with 254.
Include the next digit (2) from the dividend after 254, then repeat: 2542 / 306

On to step 4:
306 can be fit into 2542 8 times, resulting in a remainder of 94.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
The remainder is 94 after subtracting 2448 from 2542.
Fetch the next digit (0) from the dividend, attach it to 94 and continue: 940 / 306

Going ahead to step 5:
940 divided by 306 is 3 with a remainder of 22.
Use 3 as the next digit of our solution. 
Result so far: 283.0
Subtract 918 from 940 to get 22.
Grab the next digit (3) from the dividend, add it to 22, then carry on: 223 / 306

On to step 6:
If we divide 223 by 306, we get 0 and a remainder of 223.
The next digit of our result is 0. 
Result so far: 2830.0
If we take 0 away from 223, we end up with 223.
Append the next digit (7) from the dividend to 223 and continue with: 2237 / 306

On to step 7:
The number 306 fits into 2237 7 times, leaving a remainder of 95.
Put 7 as the next digit of the answer. 
Result so far: 28307.0
Subtract 2142 from 2237 to get 95.
Append the next digit (7) from the dividend to 95 and continue with: 957 / 306

Advancing to step 8:
306 goes into 957 3 times with a remainder of 39.
Write down 3 as next digit of the result. 
Result so far: 283073.0
Deduct 918 from 957 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 9:
306 goes into 390 1 times with a remainder of 84.
The next digit of our result is 1. 
Result so far: 283073.1
Deduct 306 from 390 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Let's proceed to step 10:
When dividing 840 by 306, we get 2 with a remainder of 228.
The number 2 becomes the next digit in our result. 
Result so far: 283073.12
Subtract 612 from 840 to get 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Let's proceed to step 11:
2280 divided by 306 is 7 with a remainder of 138.
Use 7 as the next digit of our solution. 
Result so far: 283073.127
Deduct 2142 from 2280 and we're left with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Advancing to step 12:
If we divide 1380 by 306, we get 4 and a remainder of 156.
Use 4 as the next digit of our solution. 
Result so far: 283073.1274
Subtract 1224 from 1380 to get 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

On to step 13:
The number 306 fits into 1560 5 times, leaving a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 283073.12745
If we take 1530 away from 1560, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 14:
When dividing 300 by 306, we get 0 with a remainder of 300.
The next digit of our result is 0. 
Result so far: 283073.12745
Subtracting 0 from 300 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Going ahead to step 15:
3000 divided by 306 is 9 with a remainder of 246.
Write down 9 as next digit of the result. 
Result so far: 283073.1274509
Subtracting 2754 from 3000 leaves us with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Moving on to step 16:
When dividing 2460 by 306, we get 8 with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 283073.12745098
Subtract 2448 from 2460 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

In conclusion, the division gives 283073.12745098 with a balance of 1.2e-08.
