802810 ÷ 99 
Our goal is to divide 802810 by 99.

Step 1:
When dividing 8 by 99, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 99

On to step 2:
The number 99 fits into 80 0 times, leaving a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Include the next digit (2) from the dividend after 80, then repeat: 802 / 99

Step 3:
99 goes into 802 8 times with a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 792 from 802 to get 10.
Take the next digit (8) from the dividend and append it to 10, then repeat: 108 / 99

Step 4:
The number 99 fits into 108 1 times, leaving a remainder of 9.
The next digit of our result is 1. 
Result so far: 81.0
Subtracting 99 from 108 leaves us with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 99

Step 5:
99 goes into 91 0 times with a remainder of 91.
Write down 0 as next digit of the result. 
Result so far: 810.0
If we take 0 away from 91, we end up with 91.
Bring next digit (0) of the dividend behind the 91 and repeat the process: 910 / 99

Going ahead to step 6:
If we divide 910 by 99, we get 9 and a remainder of 19.
Put 9 as the next digit of the answer. 
Result so far: 8109.0
Deduct 891 from 910 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 7:
When dividing 190 by 99, we get 1 with a remainder of 91.
Write down 1 as next digit of the result. 
Result so far: 8109.1
If we subtract 99 from 190, we get 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

On to step 8:
99 goes into 910 9 times with a remainder of 19.
Put 9 as the next digit of the answer. 
Result so far: 8109.19
Deduct 891 from 910 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 9:
190 divided by 99 is 1 with a remainder of 91.
Write down 1 as next digit of the result. 
Result so far: 8109.191
Subtracting 99 from 190 leaves us with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

On to step 10:
910 divided by 99 is 9 with a remainder of 19.
The next digit of our result is 9. 
Result so far: 8109.1919
If we subtract 891 from 910, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 11:
When dividing 190 by 99, we get 1 with a remainder of 91.
Record the quotient 1 as the next digit in the result. 
Result so far: 8109.19191
If we take 99 away from 190, we end up with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Let's proceed to step 12:
When dividing 910 by 99, we get 9 with a remainder of 19.
The next digit of our result is 9. 
Result so far: 8109.191919
Subtracting 891 from 910 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 13:
The number 99 fits into 190 1 times, leaving a remainder of 91.
The number 1 becomes the next digit in our result. 
Result so far: 8109.1919191
Subtracting 99 from 190 leaves us with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Advancing to step 14:
99 can be fit into 910 9 times, resulting in a remainder of 19.
The number 9 becomes the next digit in our result. 
Result so far: 8109.19191919
Deduct 891 from 910 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The final outcome is 8109.19191919, with a leftover of 1.9e-08.
