855425 ÷ 80 
We want to figure out the number of times 855425 can be divided by 80.

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
If we subtract 0 from 8, we get 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 80

Moving on to step 2:
When dividing 85 by 80, we get 1 with a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 80 away from 85, we end up with 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 80

Let's proceed to step 3:
When dividing 55 by 80, we get 0 with a remainder of 55.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we subtract 0 from 55, we get 55.
Grab the next digit (4) from the dividend, add it to 55, then carry on: 554 / 80

Moving on to step 4:
If we divide 554 by 80, we get 6 and a remainder of 74.
Record the quotient 6 as the next digit in the result. 
Result so far: 106.0
Subtract 480 from 554 to get 74.
Fetch the next digit (2) from the dividend, attach it to 74 and continue: 742 / 80

Let's proceed to step 5:
When dividing 742 by 80, we get 9 with a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 1069.0
If we take 720 away from 742, we end up with 22.
Include the next digit (5) from the dividend after 22, then repeat: 225 / 80

On to step 6:
If we divide 225 by 80, we get 2 and a remainder of 65.
The next digit of our result is 2. 
Result so far: 10692.0
If we take 160 away from 225, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 7:
When dividing 650 by 80, we get 8 with a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 10692.8
Subtracting 640 from 650 leaves us 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.

Moving on to step 8:
If we divide 100 by 80, we get 1 and a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 10692.81
The remainder is 20 after subtracting 80 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
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: 10692.812
If we take 160 away from 200, we end up 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.

Going ahead to step 10:
When dividing 400 by 80, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 10692.8125
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.

Going ahead 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: 10692.8125
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.

Moving on to step 12:
80 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10692.8125
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.

The final result is 10692.8125 with a remainder of 0.0.
