Let's divide 855420 by 8
Let's see how many times 8 fits into 855420.

Advancing to step 1:
8 goes into 8 1 times with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 0 after subtracting 8 from 8.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 8

Let's proceed to step 2:
8 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 8

On to step 3:
8 goes into 55 6 times with a remainder of 7.
The next digit of our result is 6. 
Result so far: 106.0
If we subtract 48 from 55, we get 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 8

Step 4:
If we divide 74 by 8, we get 9 and a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 1069.0
Subtracting 72 from 74 leaves us with 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 8

Let's proceed to step 5:
The number 8 fits into 22 2 times, leaving a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 10692.0
If we subtract 16 from 22, we get 6.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 8

Advancing to step 6:
60 divided by 8 is 7 with a remainder of 4.
The next digit of our result is 7. 
Result so far: 106927.0
Subtract 56 from 60 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
8 can be fit into 40 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 106927.5
Subtracting 40 from 40 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.

Advancing to step 8:
0 divided by 8 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 106927.5
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.

Going ahead to step 9:
8 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: 106927.5
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.

Our division results in 106927.5 with a remaining 0.0.
