We're dividing 862451 by 80 
We're looking to find how many times 80 goes into 862451.

Let's proceed to step 1:
80 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
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:
When dividing 86 by 80, we get 1 with a remainder of 6.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 80 from 86 to get 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 80

Moving on to step 3:
80 can be fit into 62 0 times, resulting in a remainder of 62.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtracting 0 from 62 leaves us with 62.
Bring next digit (4) of the dividend behind the 62 and repeat the process: 624 / 80

Advancing to step 4:
If we divide 624 by 80, we get 7 and a remainder of 64.
Put 7 as the next digit of the answer. 
Result so far: 107.0
The remainder is 64 after subtracting 560 from 624.
Append the next digit (5) from the dividend to 64 and continue with: 645 / 80

Step 5:
80 can be fit into 645 8 times, resulting in a remainder of 5.
The number 8 becomes the next digit in our result. 
Result so far: 1078.0
Subtracting 640 from 645 leaves us with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 80

On to step 6:
51 divided by 80 is 0 with a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 10780.0
The remainder is 51 after subtracting 0 from 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 7:
510 divided by 80 is 6 with a remainder of 30.
Use 6 as the next digit of our solution. 
Result so far: 10780.6
Subtracting 480 from 510 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.

Let's proceed to step 8:
80 can be fit into 300 3 times, resulting in a remainder of 60.
Write down 3 as next digit of the result. 
Result so far: 10780.63
The remainder is 60 after subtracting 240 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 9:
When dividing 600 by 80, we get 7 with a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 10780.637
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.

Moving on to step 10:
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: 10780.6375
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.

Advancing to step 11:
80 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10780.6375
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.

Going ahead to step 12:
0 divided by 80 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10780.6375
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.

In conclusion, the division gives 10780.6375 with a balance of 0.0.
