Let's divide 817385 by 80
Our goal is to divide 817385 by 80.

On to step 1:
80 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
If we subtract 0 from 8, we get 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 80

Let's proceed 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 take 80 away from 81, we end up with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 80

Going ahead to step 3:
If we divide 17 by 80, we get 0 and a remainder of 17.
The next digit of our result is 0. 
Result so far: 10.0
Subtract 0 from 17 to get 17.
Include the next digit (3) from the dividend after 17, then repeat: 173 / 80

On to step 4:
173 divided by 80 is 2 with a remainder of 13.
Put 2 as the next digit of the answer. 
Result so far: 102.0
If we subtract 160 from 173, we get 13.
Append the next digit (8) from the dividend to 13 and continue with: 138 / 80

Let's proceed to step 5:
The number 80 fits into 138 1 times, leaving a remainder of 58.
The next digit of our result is 1. 
Result so far: 1021.0
If we take 80 away from 138, we end up with 58.
Take the next digit (5) from the dividend and append it to 58, then repeat: 585 / 80

On to step 6:
If we divide 585 by 80, we get 7 and a remainder of 25.
Use 7 as the next digit of our solution. 
Result so far: 10217.0
Deduct 560 from 585 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 7:
80 can be fit into 250 3 times, resulting in a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 10217.3
If we take 240 away from 250, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
If we divide 100 by 80, we get 1 and a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 10217.31
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.

Moving on to step 9:
80 can be fit into 200 2 times, resulting in a remainder of 40.
The next digit of our result is 2. 
Result so far: 10217.312
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.

Going ahead to step 10:
80 goes into 400 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 10217.3125
If we subtract 400 from 400, 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.

On to step 11:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10217.3125
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.

Let's proceed to step 12:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10217.3125
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.

Our division results in 10217.3125 with a remaining 0.0.
