We divide 813217 by 80
Our goal is to divide 813217 by 80.

Going ahead to step 1:
If we divide 8 by 80, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 80

On to step 2:
If we divide 81 by 80, we get 1 and a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 80 from 81, we get 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 80

Moving on to step 3:
The number 80 fits into 13 0 times, leaving a remainder of 13.
The next digit of our result is 0. 
Result so far: 10.0
Subtract 0 from 13 to get 13.
Bring next digit (2) of the dividend behind the 13 and repeat the process: 132 / 80

On to step 4:
If we divide 132 by 80, we get 1 and a remainder of 52.
Record the quotient 1 as the next digit in the result. 
Result so far: 101.0
Subtract 80 from 132 to get 52.
Take the next digit (1) from the dividend and append it to 52, then repeat: 521 / 80

Step 5:
When dividing 521 by 80, we get 6 with a remainder of 41.
Use 6 as the next digit of our solution. 
Result so far: 1016.0
Subtract 480 from 521 to get 41.
Fetch the next digit (7) from the dividend, attach it to 41 and continue: 417 / 80

Step 6:
80 can be fit into 417 5 times, resulting in a remainder of 17.
Put 5 as the next digit of the answer. 
Result so far: 10165.0
The remainder is 17 after subtracting 400 from 417.
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.
Use 2 as the next digit of our solution. 
Result so far: 10165.2
If we subtract 160 from 170, we 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.

On to step 8:
The number 80 fits into 100 1 times, leaving a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 10165.21
If we subtract 80 from 100, we get 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:
80 goes into 200 2 times with a remainder of 40.
The next digit of our result is 2. 
Result so far: 10165.212
If we subtract 160 from 200, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
80 can be fit into 400 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 10165.2125
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:
0 divided by 80 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10165.2125
Subtract 0 from 0 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.

Moving on to step 12:
If we divide 0 by 80, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10165.2125
Subtracting 0 from 0 leaves us 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.

Our division results in 10165.2125 with a remaining 0.0.
