863212 ÷ 91 
We're looking to find how many times 91 goes into 863212.

Going ahead to step 1:
If we divide 8 by 91, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 91

Moving on to step 2:
86 divided by 91 is 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.
Take the next digit (3) from the dividend and append it to 86, then repeat: 863 / 91

On to step 3:
91 can be fit into 863 9 times, resulting in a remainder of 44.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 819 from 863, we get 44.
Bring next digit (2) of the dividend behind the 44 and repeat the process: 442 / 91

Step 4:
If we divide 442 by 91, we get 4 and a remainder of 78.
Write down 4 as next digit of the result. 
Result so far: 94.0
Deduct 364 from 442 and we're left with 78.
Include the next digit (1) from the dividend after 78, then repeat: 781 / 91

On to step 5:
The number 91 fits into 781 8 times, leaving a remainder of 53.
The number 8 becomes the next digit in our result. 
Result so far: 948.0
Subtract 728 from 781 to get 53.
Bring next digit (2) of the dividend behind the 53 and repeat the process: 532 / 91

On to step 6:
If we divide 532 by 91, we get 5 and a remainder of 77.
Record the quotient 5 as the next digit in the result. 
Result so far: 9485.0
Subtracting 455 from 532 leaves us 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.

Advancing to step 7:
91 can be fit into 770 8 times, resulting in a remainder of 42.
Write down 8 as next digit of the result. 
Result so far: 9485.8
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.

On to step 8:
The number 91 fits into 420 4 times, leaving a remainder of 56.
Record the quotient 4 as the next digit in the result. 
Result so far: 9485.84
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.

Let's proceed to step 9:
When dividing 560 by 91, we get 6 with a remainder of 14.
The next digit of our result is 6. 
Result so far: 9485.846
If we subtract 546 from 560, we get 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 10:
140 divided by 91 is 1 with a remainder of 49.
Write down 1 as next digit of the result. 
Result so far: 9485.8461
Subtract 91 from 140 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 11:
The number 91 fits into 490 5 times, leaving a remainder of 35.
The next digit of our result is 5. 
Result so far: 9485.84615
Subtracting 455 from 490 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.

Moving on to step 12:
The number 91 fits into 350 3 times, leaving a remainder of 77.
The number 3 becomes the next digit in our result. 
Result so far: 9485.846153
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.

Moving on to step 13:
If we divide 770 by 91, we get 8 and a remainder of 42.
The number 8 becomes the next digit in our result. 
Result so far: 9485.8461538
Deduct 728 from 770 and we're left 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.

Step 14:
If we divide 420 by 91, we get 4 and a remainder of 56.
Use 4 as the next digit of our solution. 
Result so far: 9485.84615384
Subtracting 364 from 420 leaves us 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.

The final outcome is 9485.84615384, with a leftover of 5.6e-08.
