808230 ÷ 81 
We want to figure out the number of times 808230 can be divided by 81.

On to step 1:
8 divided by 81 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 81

Step 2:
The number 81 fits into 80 0 times, leaving a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Bring next digit (8) of the dividend behind the 80 and repeat the process: 808 / 81

Going ahead to step 3:
808 divided by 81 is 9 with a remainder of 79.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 729 away from 808, we end up with 79.
Fetch the next digit (2) from the dividend, attach it to 79 and continue: 792 / 81

Going ahead to step 4:
792 divided by 81 is 9 with a remainder of 63.
Use 9 as the next digit of our solution. 
Result so far: 99.0
Subtracting 729 from 792 leaves us with 63.
Fetch the next digit (3) from the dividend, attach it to 63 and continue: 633 / 81

Let's proceed to step 5:
81 goes into 633 7 times with a remainder of 66.
Write down 7 as next digit of the result. 
Result so far: 997.0
Subtract 567 from 633 to get 66.
Grab the next digit (0) from the dividend, add it to 66, then carry on: 660 / 81

Step 6:
81 goes into 660 8 times with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 9978.0
If we take 648 away from 660, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 7:
When dividing 120 by 81, we get 1 with a remainder of 39.
The number 1 becomes the next digit in our result. 
Result so far: 9978.1
Subtracting 81 from 120 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 8:
81 goes into 390 4 times with a remainder of 66.
The number 4 becomes the next digit in our result. 
Result so far: 9978.14
Subtracting 324 from 390 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 9:
81 goes into 660 8 times with a remainder of 12.
The next digit of our result is 8. 
Result so far: 9978.148
Deduct 648 from 660 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 10:
When dividing 120 by 81, we get 1 with a remainder of 39.
Use 1 as the next digit of our solution. 
Result so far: 9978.1481
Subtracting 81 from 120 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 11:
81 can be fit into 390 4 times, resulting in a remainder of 66.
Put 4 as the next digit of the answer. 
Result so far: 9978.14814
Deduct 324 from 390 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 12:
81 can be fit into 660 8 times, resulting in a remainder of 12.
The next digit of our result is 8. 
Result so far: 9978.148148
Subtract 648 from 660 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 13:
If we divide 120 by 81, we get 1 and a remainder of 39.
The next digit of our result is 1. 
Result so far: 9978.1481481
Subtracting 81 from 120 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 14:
The number 81 fits into 390 4 times, leaving a remainder of 66.
Use 4 as the next digit of our solution. 
Result so far: 9978.14814814
The remainder is 66 after subtracting 324 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Our division results in 9978.14814814 with a remaining 6.6e-08.
