We divide 816497 by 80
Let's see how many times 80 fits into 816497.

On to step 1:
When dividing 8 by 80, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 80

Step 2:
80 can be fit into 81 1 times, resulting in a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 80 from 81 leaves us with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 80

Step 3:
The number 80 fits into 16 0 times, leaving a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtract 0 from 16 to get 16.
Bring next digit (4) of the dividend behind the 16 and repeat the process: 164 / 80

Going ahead to step 4:
The number 80 fits into 164 2 times, leaving a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 102.0
Subtract 160 from 164 to get 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 80

Step 5:
If we divide 49 by 80, we get 0 and a remainder of 49.
Put 0 as the next digit of the answer. 
Result so far: 1020.0
If we take 0 away from 49, we end up with 49.
Include the next digit (7) from the dividend after 49, then repeat: 497 / 80

Step 6:
497 divided by 80 is 6 with a remainder of 17.
The next digit of our result is 6. 
Result so far: 10206.0
If we take 480 away from 497, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 7:
When dividing 170 by 80, we get 2 with a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 10206.2
Subtract 160 from 170 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
100 divided by 80 is 1 with a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 10206.21
Subtracting 80 from 100 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
When dividing 200 by 80, we get 2 with a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 10206.212
The remainder is 40 after subtracting 160 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 10:
400 divided by 80 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 10206.2125
Subtract 400 from 400 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 11:
The number 80 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 10206.2125
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 12:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10206.2125
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 10206.2125 and a remainder of 0.0.
