We look at the division of 85846971 by 309 
We want to divide 85846971 by 309.

On to step 1:
309 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 309

Advancing to step 2:
If we divide 85 by 309, we get 0 and a remainder of 85.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 85, we end up with 85.
Fetch the next digit (8) from the dividend, attach it to 85 and continue: 858 / 309

Let's proceed to step 3:
The number 309 fits into 858 2 times, leaving a remainder of 240.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 240 after subtracting 618 from 858.
Bring next digit (4) of the dividend behind the 240 and repeat the process: 2404 / 309

Advancing to step 4:
The number 309 fits into 2404 7 times, leaving a remainder of 241.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
Subtract 2163 from 2404 to get 241.
Fetch the next digit (6) from the dividend, attach it to 241 and continue: 2416 / 309

Going ahead to step 5:
The number 309 fits into 2416 7 times, leaving a remainder of 253.
Record the quotient 7 as the next digit in the result. 
Result so far: 277.0
If we subtract 2163 from 2416, we get 253.
Include the next digit (9) from the dividend after 253, then repeat: 2539 / 309

Step 6:
2539 divided by 309 is 8 with a remainder of 67.
The number 8 becomes the next digit in our result. 
Result so far: 2778.0
Subtract 2472 from 2539 to get 67.
Grab the next digit (7) from the dividend, add it to 67, then carry on: 677 / 309

Moving on to step 7:
When dividing 677 by 309, we get 2 with a remainder of 59.
Use 2 as the next digit of our solution. 
Result so far: 27782.0
If we take 618 away from 677, we end up with 59.
Fetch the next digit (1) from the dividend, attach it to 59 and continue: 591 / 309

Step 8:
The number 309 fits into 591 1 times, leaving a remainder of 282.
Write down 1 as next digit of the result. 
Result so far: 277821.0
If we subtract 309 from 591, we get 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Let's proceed to step 9:
When dividing 2820 by 309, we get 9 with a remainder of 39.
The number 9 becomes the next digit in our result. 
Result so far: 277821.9
Subtracting 2781 from 2820 leaves us 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.

Step 10:
309 can be fit into 390 1 times, resulting in a remainder of 81.
The next digit of our result is 1. 
Result so far: 277821.91
The remainder is 81 after subtracting 309 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Advancing to step 11:
When dividing 810 by 309, we get 2 with a remainder of 192.
The next digit of our result is 2. 
Result so far: 277821.912
If we take 618 away from 810, we end up with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Going ahead to step 12:
When dividing 1920 by 309, we get 6 with a remainder of 66.
The next digit of our result is 6. 
Result so far: 277821.9126
If we take 1854 away from 1920, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 13:
309 can be fit into 660 2 times, resulting in a remainder of 42.
Write down 2 as next digit of the result. 
Result so far: 277821.91262
Subtracting 618 from 660 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 14:
When dividing 420 by 309, we get 1 with a remainder of 111.
Record the quotient 1 as the next digit in the result. 
Result so far: 277821.912621
If we subtract 309 from 420, we get 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Step 15:
309 goes into 1110 3 times with a remainder of 183.
Record the quotient 3 as the next digit in the result. 
Result so far: 277821.9126213
Subtracting 927 from 1110 leaves us with 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

On to step 16:
When dividing 1830 by 309, we get 5 with a remainder of 285.
The next digit of our result is 5. 
Result so far: 277821.91262135
Subtracting 1545 from 1830 leaves us with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

The final outcome is 277821.91262135, with a leftover of 2.85e-07.
