809510 ÷ 99 
We want to figure out the number of times 809510 can be divided by 99.

Advancing to step 1:
99 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 99

Step 2:
If we divide 80 by 99, we get 0 and a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Fetch the next digit (9) from the dividend, attach it to 80 and continue: 809 / 99

Going ahead to step 3:
The number 99 fits into 809 8 times, leaving a remainder of 17.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 792 from 809 to get 17.
Include the next digit (5) from the dividend after 17, then repeat: 175 / 99

Step 4:
If we divide 175 by 99, we get 1 and a remainder of 76.
Use 1 as the next digit of our solution. 
Result so far: 81.0
Subtract 99 from 175 to get 76.
Include the next digit (1) from the dividend after 76, then repeat: 761 / 99

Step 5:
If we divide 761 by 99, we get 7 and a remainder of 68.
Record the quotient 7 as the next digit in the result. 
Result so far: 817.0
If we subtract 693 from 761, we get 68.
Include the next digit (0) from the dividend after 68, then repeat: 680 / 99

On to step 6:
99 can be fit into 680 6 times, resulting in a remainder of 86.
The next digit of our result is 6. 
Result so far: 8176.0
Subtracting 594 from 680 leaves us with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Advancing to step 7:
The number 99 fits into 860 8 times, leaving a remainder of 68.
Record the quotient 8 as the next digit in the result. 
Result so far: 8176.8
The remainder is 68 after subtracting 792 from 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 8:
680 divided by 99 is 6 with a remainder of 86.
Record the quotient 6 as the next digit in the result. 
Result so far: 8176.86
If we take 594 away from 680, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Going ahead to step 9:
The number 99 fits into 860 8 times, leaving a remainder of 68.
The next digit of our result is 8. 
Result so far: 8176.868
Deduct 792 from 860 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 10:
When dividing 680 by 99, we get 6 with a remainder of 86.
Write down 6 as next digit of the result. 
Result so far: 8176.8686
If we subtract 594 from 680, we get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

On to step 11:
99 can be fit into 860 8 times, resulting in a remainder of 68.
Put 8 as the next digit of the answer. 
Result so far: 8176.86868
Subtracting 792 from 860 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 12:
The number 99 fits into 680 6 times, leaving a remainder of 86.
Record the quotient 6 as the next digit in the result. 
Result so far: 8176.868686
Deduct 594 from 680 and we're left with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Going ahead to step 13:
860 divided by 99 is 8 with a remainder of 68.
Record the quotient 8 as the next digit in the result. 
Result so far: 8176.8686868
If we take 792 away from 860, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 14:
680 divided by 99 is 6 with a remainder of 86.
Put 6 as the next digit of the answer. 
Result so far: 8176.86868686
Subtract 594 from 680 to get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

The final result is 8176.86868686 with a remainder of 8.6e-08.
