We're dividing 865899 by 91 
We want to divide 865899 by 91.

Going ahead to step 1:
When dividing 8 by 91, we get 0 with 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.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 91

Step 2:
When dividing 86 by 91, we get 0 with a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Append the next digit (5) from the dividend to 86 and continue with: 865 / 91

Moving on to step 3:
865 divided by 91 is 9 with a remainder of 46.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we take 819 away from 865, we end up with 46.
Bring next digit (8) of the dividend behind the 46 and repeat the process: 468 / 91

Step 4:
The number 91 fits into 468 5 times, leaving a remainder of 13.
Record the quotient 5 as the next digit in the result. 
Result so far: 95.0
Subtract 455 from 468 to get 13.
Grab the next digit (9) from the dividend, add it to 13, then carry on: 139 / 91

Advancing to step 5:
If we divide 139 by 91, we get 1 and a remainder of 48.
Use 1 as the next digit of our solution. 
Result so far: 951.0
Subtracting 91 from 139 leaves us with 48.
Append the next digit (9) from the dividend to 48 and continue with: 489 / 91

Advancing to step 6:
91 can be fit into 489 5 times, resulting in a remainder of 34.
Put 5 as the next digit of the answer. 
Result so far: 9515.0
Subtract 455 from 489 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 7:
If we divide 340 by 91, we get 3 and a remainder of 67.
The next digit of our result is 3. 
Result so far: 9515.3
Subtracting 273 from 340 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

On to step 8:
If we divide 670 by 91, we get 7 and a remainder of 33.
Put 7 as the next digit of the answer. 
Result so far: 9515.37
Subtract 637 from 670 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 9:
91 can be fit into 330 3 times, resulting in a remainder of 57.
The number 3 becomes the next digit in our result. 
Result so far: 9515.373
If we take 273 away from 330, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 10:
570 divided by 91 is 6 with a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 9515.3736
The remainder is 24 after subtracting 546 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 11:
91 can be fit into 240 2 times, resulting in a remainder of 58.
The next digit of our result is 2. 
Result so far: 9515.37362
If we take 182 away from 240, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 12:
The number 91 fits into 580 6 times, leaving a remainder of 34.
The next digit of our result is 6. 
Result so far: 9515.373626
Subtract 546 from 580 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 13:
340 divided by 91 is 3 with a remainder of 67.
Record the quotient 3 as the next digit in the result. 
Result so far: 9515.3736263
The remainder is 67 after subtracting 273 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

On to step 14:
91 goes into 670 7 times with a remainder of 33.
Put 7 as the next digit of the answer. 
Result so far: 9515.37362637
If we take 637 away from 670, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

The final outcome is 9515.37362637, with a leftover of 3.3e-08.
