99864873 ÷ 82 
Our goal is to divide 99864873 by 82.

On to step 1:
82 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 82

Moving on to step 2:
When dividing 99 by 82, we get 1 with a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 82 away from 99, we end up with 17.
Bring next digit (8) of the dividend behind the 17 and repeat the process: 178 / 82

Advancing to step 3:
The number 82 fits into 178 2 times, leaving a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtract 164 from 178 to get 14.
Append the next digit (6) from the dividend to 14 and continue with: 146 / 82

Let's proceed to step 4:
When dividing 146 by 82, we get 1 with a remainder of 64.
Use 1 as the next digit of our solution. 
Result so far: 121.0
Subtract 82 from 146 to get 64.
Grab the next digit (4) from the dividend, add it to 64, then carry on: 644 / 82

Advancing to step 5:
644 divided by 82 is 7 with a remainder of 70.
Use 7 as the next digit of our solution. 
Result so far: 1217.0
The remainder is 70 after subtracting 574 from 644.
Take the next digit (8) from the dividend and append it to 70, then repeat: 708 / 82

Step 6:
The number 82 fits into 708 8 times, leaving a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 12178.0
The remainder is 52 after subtracting 656 from 708.
Include the next digit (7) from the dividend after 52, then repeat: 527 / 82

Moving on to step 7:
527 divided by 82 is 6 with a remainder of 35.
Put 6 as the next digit of the answer. 
Result so far: 121786.0
Deduct 492 from 527 and we're left with 35.
Grab the next digit (3) from the dividend, add it to 35, then carry on: 353 / 82

Step 8:
82 goes into 353 4 times with a remainder of 25.
Write down 4 as next digit of the result. 
Result so far: 1217864.0
If we take 328 away from 353, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 9:
The number 82 fits into 250 3 times, leaving a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 1217864.3
The remainder is 4 after subtracting 246 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 10:
82 goes into 40 0 times with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 1217864.3
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 11:
The number 82 fits into 400 4 times, leaving a remainder of 72.
Put 4 as the next digit of the answer. 
Result so far: 1217864.304
The remainder is 72 after subtracting 328 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 12:
When dividing 720 by 82, we get 8 with a remainder of 64.
Record the quotient 8 as the next digit in the result. 
Result so far: 1217864.3048
The remainder is 64 after subtracting 656 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 13:
82 can be fit into 640 7 times, resulting in a remainder of 66.
Write down 7 as next digit of the result. 
Result so far: 1217864.30487
If we subtract 574 from 640, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 14:
82 can be fit into 660 8 times, resulting in a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 1217864.304878
If we subtract 656 from 660, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 15:
The number 82 fits into 40 0 times, leaving a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 1217864.304878
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 16:
When dividing 400 by 82, we get 4 with a remainder of 72.
Write down 4 as next digit of the result. 
Result so far: 1217864.30487804
Deduct 328 from 400 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The final result is 1217864.30487804 with a remainder of 7.2e-08.
