862874 divided by 80 
Our goal is to divide 862874 by 80.

Let's proceed to step 1:
80 can be fit into 8 0 times, resulting in 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.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 80

Step 2:
The number 80 fits into 86 1 times, leaving a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 80 from 86, we get 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 80

Let's proceed to step 3:
When dividing 62 by 80, we get 0 with a remainder of 62.
Write down 0 as next digit of the result. 
Result so far: 10.0
Deduct 0 from 62 and we're left with 62.
Include the next digit (8) from the dividend after 62, then repeat: 628 / 80

Advancing to step 4:
When dividing 628 by 80, we get 7 with a remainder of 68.
The number 7 becomes the next digit in our result. 
Result so far: 107.0
If we subtract 560 from 628, we get 68.
Include the next digit (7) from the dividend after 68, then repeat: 687 / 80

On to step 5:
The number 80 fits into 687 8 times, leaving a remainder of 47.
Record the quotient 8 as the next digit in the result. 
Result so far: 1078.0
Subtracting 640 from 687 leaves us with 47.
Append the next digit (4) from the dividend to 47 and continue with: 474 / 80

Step 6:
80 can be fit into 474 5 times, resulting in a remainder of 74.
Use 5 as the next digit of our solution. 
Result so far: 10785.0
If we subtract 400 from 474, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 7:
The number 80 fits into 740 9 times, leaving a remainder of 20.
The next digit of our result is 9. 
Result so far: 10785.9
If we subtract 720 from 740, 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.

Let's proceed to step 8:
When dividing 200 by 80, we get 2 with a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 10785.92
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 9:
The number 80 fits into 400 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 10785.925
The remainder is 0 after subtracting 400 from 400.
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 10:
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: 10785.925
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.

On to step 11:
When dividing 0 by 80, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10785.925
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.

The final outcome is 10785.925, with a leftover of 0.0.
