We look at the division of 285684 by 91 
Let's see how many times 91 fits into 285684.

Going ahead to step 1:
The number 91 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 91

Advancing to step 2:
The number 91 fits into 28 0 times, leaving a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 28, we get 28.
Take the next digit (5) from the dividend and append it to 28, then repeat: 285 / 91

Going ahead to step 3:
285 divided by 91 is 3 with a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 12 after subtracting 273 from 285.
Grab the next digit (6) from the dividend, add it to 12, then carry on: 126 / 91

On to step 4:
126 divided by 91 is 1 with a remainder of 35.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
The remainder is 35 after subtracting 91 from 126.
Fetch the next digit (8) from the dividend, attach it to 35 and continue: 358 / 91

Step 5:
When dividing 358 by 91, we get 3 with a remainder of 85.
The number 3 becomes the next digit in our result. 
Result so far: 313.0
The remainder is 85 after subtracting 273 from 358.
Append the next digit (4) from the dividend to 85 and continue with: 854 / 91

Step 6:
If we divide 854 by 91, we get 9 and a remainder of 35.
Record the quotient 9 as the next digit in the result. 
Result so far: 3139.0
Subtracting 819 from 854 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 7:
The number 91 fits into 350 3 times, leaving a remainder of 77.
The next digit of our result is 3. 
Result so far: 3139.3
If we take 273 away from 350, we end up with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Moving on to step 8:
When dividing 770 by 91, we get 8 with a remainder of 42.
Record the quotient 8 as the next digit in the result. 
Result so far: 3139.38
If we subtract 728 from 770, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 9:
91 can be fit into 420 4 times, resulting in a remainder of 56.
The next digit of our result is 4. 
Result so far: 3139.384
Deduct 364 from 420 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 10:
91 can be fit into 560 6 times, resulting in a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 3139.3846
Subtracting 546 from 560 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 11:
When dividing 140 by 91, we get 1 with a remainder of 49.
The number 1 becomes the next digit in our result. 
Result so far: 3139.38461
If we take 91 away from 140, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 12:
When dividing 490 by 91, we get 5 with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 3139.384615
The remainder is 35 after subtracting 455 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 13:
If we divide 350 by 91, we get 3 and a remainder of 77.
The number 3 becomes the next digit in our result. 
Result so far: 3139.3846153
The remainder is 77 after subtracting 273 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Going ahead to step 14:
If we divide 770 by 91, we get 8 and a remainder of 42.
Put 8 as the next digit of the answer. 
Result so far: 3139.38461538
The remainder is 42 after subtracting 728 from 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final result is 3139.38461538 with a remainder of 4.2e-08.
