We're dividing 815723 by 80 
We want to divide 815723 by 80.

Going ahead to step 1:
When dividing 8 by 80, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 80

Step 2:
81 divided by 80 is 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 80 from 81 leaves us with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 80

Going ahead to step 3:
15 divided by 80 is 0 with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we subtract 0 from 15, we get 15.
Take the next digit (7) from the dividend and append it to 15, then repeat: 157 / 80

Advancing to step 4:
If we divide 157 by 80, we get 1 and a remainder of 77.
The next digit of our result is 1. 
Result so far: 101.0
Deduct 80 from 157 and we're left with 77.
Bring next digit (2) of the dividend behind the 77 and repeat the process: 772 / 80

Step 5:
772 divided by 80 is 9 with a remainder of 52.
Record the quotient 9 as the next digit in the result. 
Result so far: 1019.0
Subtract 720 from 772 to get 52.
Append the next digit (3) from the dividend to 52 and continue with: 523 / 80

Step 6:
When dividing 523 by 80, we get 6 with a remainder of 43.
Write down 6 as next digit of the result. 
Result so far: 10196.0
If we take 480 away from 523, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 7:
80 can be fit into 430 5 times, resulting in a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 10196.5
Subtracting 400 from 430 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
300 divided by 80 is 3 with a remainder of 60.
Write down 3 as next digit of the result. 
Result so far: 10196.53
If we take 240 away from 300, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 9:
When dividing 600 by 80, we get 7 with a remainder of 40.
Put 7 as the next digit of the answer. 
Result so far: 10196.537
Deduct 560 from 600 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 10:
80 goes into 400 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 10196.5375
If we take 400 away from 400, 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 11:
80 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10196.5375
Deduct 0 from 0 and we're left 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:
0 divided by 80 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10196.5375
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.

After the division, we end up with 10196.5375 and a remainder of 0.0.
