91851 ÷ 82 
We're looking to find how many times 82 goes into 91851.

Going ahead to step 1:
9 divided by 82 is 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 82

Moving on to step 2:
82 can be fit into 91 1 times, resulting in a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 82 from 91 leaves us with 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 82

Going ahead to step 3:
When dividing 98 by 82, we get 1 with a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtract 82 from 98 to get 16.
Grab the next digit (5) from the dividend, add it to 16, then carry on: 165 / 82

Let's proceed to step 4:
82 goes into 165 2 times with a remainder of 1.
The next digit of our result is 2. 
Result so far: 112.0
If we subtract 164 from 165, we get 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 82

Advancing to step 5:
The number 82 fits into 11 0 times, leaving a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 1120.0
Deduct 0 from 11 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 6:
If we divide 110 by 82, we get 1 and a remainder of 28.
Use 1 as the next digit of our solution. 
Result so far: 1120.1
Subtract 82 from 110 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 7:
82 goes into 280 3 times with a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 1120.13
Subtract 246 from 280 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 8:
82 can be fit into 340 4 times, resulting in a remainder of 12.
The next digit of our result is 4. 
Result so far: 1120.134
Subtract 328 from 340 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
When dividing 120 by 82, we get 1 with a remainder of 38.
The number 1 becomes the next digit in our result. 
Result so far: 1120.1341
If we subtract 82 from 120, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 10:
82 goes into 380 4 times with a remainder of 52.
Use 4 as the next digit of our solution. 
Result so far: 1120.13414
If we subtract 328 from 380, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 11:
82 goes into 520 6 times with a remainder of 28.
The next digit of our result is 6. 
Result so far: 1120.134146
If we subtract 492 from 520, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 12:
280 divided by 82 is 3 with a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 1120.1341463
The remainder is 34 after subtracting 246 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 13:
82 can be fit into 340 4 times, resulting in a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 1120.13414634
If we subtract 328 from 340, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final result is 1120.13414634 with a remainder of 1.2e-08.
