819881 ÷ 99 
We want to figure out the number of times 819881 can be divided by 99.

Let's proceed to step 1:
If we divide 8 by 99, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 99

Let's proceed to step 2:
If we divide 81 by 99, we get 0 and a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Grab the next digit (9) from the dividend, add it to 81, then carry on: 819 / 99

Moving on to step 3:
If we divide 819 by 99, we get 8 and a remainder of 27.
The next digit of our result is 8. 
Result so far: 8.0
The remainder is 27 after subtracting 792 from 819.
Include the next digit (8) from the dividend after 27, then repeat: 278 / 99

Going ahead to step 4:
If we divide 278 by 99, we get 2 and a remainder of 80.
Use 2 as the next digit of our solution. 
Result so far: 82.0
Subtracting 198 from 278 leaves us with 80.
Bring next digit (8) of the dividend behind the 80 and repeat the process: 808 / 99

On to step 5:
When dividing 808 by 99, we get 8 with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 828.0
If we subtract 792 from 808, we get 16.
Include the next digit (1) from the dividend after 16, then repeat: 161 / 99

Step 6:
When dividing 161 by 99, we get 1 with a remainder of 62.
Record the quotient 1 as the next digit in the result. 
Result so far: 8281.0
If we subtract 99 from 161, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 7:
620 divided by 99 is 6 with a remainder of 26.
Put 6 as the next digit of the answer. 
Result so far: 8281.6
Subtracting 594 from 620 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 8:
If we divide 260 by 99, we get 2 and a remainder of 62.
The next digit of our result is 2. 
Result so far: 8281.62
The remainder is 62 after subtracting 198 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 9:
The number 99 fits into 620 6 times, leaving a remainder of 26.
The next digit of our result is 6. 
Result so far: 8281.626
If we subtract 594 from 620, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 10:
The number 99 fits into 260 2 times, leaving a remainder of 62.
The next digit of our result is 2. 
Result so far: 8281.6262
The remainder is 62 after subtracting 198 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 11:
99 can be fit into 620 6 times, resulting in a remainder of 26.
Write down 6 as next digit of the result. 
Result so far: 8281.62626
Subtract 594 from 620 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 12:
When dividing 260 by 99, we get 2 with a remainder of 62.
Record the quotient 2 as the next digit in the result. 
Result so far: 8281.626262
Deduct 198 from 260 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 13:
If we divide 620 by 99, we get 6 and a remainder of 26.
Put 6 as the next digit of the answer. 
Result so far: 8281.6262626
Deduct 594 from 620 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 14:
If we divide 260 by 99, we get 2 and a remainder of 62.
Record the quotient 2 as the next digit in the result. 
Result so far: 8281.62626262
If we take 198 away from 260, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

The final result is 8281.62626262 with a remainder of 6.2e-08.
