The remainder is 8 after subtracting 0 from 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 309

Advancing to step 2:
The number 309 fits into 85 0 times, leaving a remainder of 85.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 85 after subtracting 0 from 85.
Bring next digit (2) of the dividend behind the 85 and repeat the process: 852 / 309

Going ahead to step 3:
The number 309 fits into 852 2 times, leaving a remainder of 234.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 618 from 852 and we're left with 234.
Grab the next digit (2) from the dividend, add it to 234, then carry on: 2342 / 309

Moving on to step 4:
When dividing 2342 by 309, we get 7 with a remainder of 179.
Put 7 as the next digit of the answer. 
Result so far: 27.0
Subtracting 2163 from 2342 leaves us with 179.
Grab the next digit (9) from the dividend, add it to 179, then carry on: 1799 / 309

Advancing to step 5:
309 can be fit into 1799 5 times, resulting in a remainder of 254.
The number 5 becomes the next digit in our result. 
Result so far: 275.0
Subtracting 1545 from 1799 leaves us with 254.
Include the next digit (8) from the dividend after 254, then repeat: 2548 / 309

On to step 6:
When dividing 2548 by 309, we get 8 with a remainder of 76.
Record the quotient 8 as the next digit in the result. 
Result so far: 2758.0
Subtracting 2472 from 2548 leaves us with 76.
Fetch the next digit (3) from the dividend, attach it to 76 and continue: 763 / 309

Moving on to step 7:
If we divide 763 by 309, we get 2 and a remainder of 145.
Write down 2 as next digit of the result. 
Result so far: 27582.0
The remainder is 145 after subtracting 618 from 763.
Fetch the next digit (5) from the dividend, attach it to 145 and continue: 1455 / 309

Step 8:
When dividing 1455 by 309, we get 4 with a remainder of 219.
The next digit of our result is 4. 
Result so far: 275824.0
Subtract 1236 from 1455 to get 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

On to step 9:
When dividing 2190 by 309, we get 7 with a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 275824.7
Deduct 2163 from 2190 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 10:
If we divide 270 by 309, we get 0 and a remainder of 270.
The next digit of our result is 0. 
Result so far: 275824.7
If we take 0 away from 270, we end up with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Moving on to step 11:
309 goes into 2700 8 times with a remainder of 228.
Write down 8 as next digit of the result. 
Result so far: 275824.708
If we subtract 2472 from 2700, we 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.

Moving on to step 12:
When dividing 2280 by 309, we get 7 with a remainder of 117.
Put 7 as the next digit of the answer. 
Result so far: 275824.7087
If we subtract 2163 from 2280, we get 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

On to step 13:
1170 divided by 309 is 3 with a remainder of 243.
Record the quotient 3 as the next digit in the result. 
Result so far: 275824.70873
Subtracting 927 from 1170 leaves us with 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

Advancing to step 14:
When dividing 2430 by 309, we get 7 with a remainder of 267.
The next digit of our result is 7. 
Result so far: 275824.708737
Subtracting 2163 from 2430 leaves us with 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

Let's proceed to step 15:
The number 309 fits into 2670 8 times, leaving a remainder of 198.
The number 8 becomes the next digit in our result. 
Result so far: 275824.7087378
The remainder is 198 after subtracting 2472 from 2670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Moving on to step 16:
If we divide 1980 by 309, we get 6 and a remainder of 126.
The next digit of our result is 6. 
Result so far: 275824.70873786
If we subtract 1854 from 1980, we get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

The final outcome is 275824.70873786, with a leftover of 1.26e-07.
