855560 divided by 2 
Let's see how many times 2 fits into 855560.

Advancing to step 1:
When dividing 8 by 2, we get 4 with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 8 from 8, we get 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 2

Moving on to step 2:
2 can be fit into 5 2 times, resulting in a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 42.0
If we subtract 4 from 5, we get 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 2

Going ahead to step 3:
2 can be fit into 15 7 times, resulting in a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 427.0
If we take 14 away from 15, we end up with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 2

On to step 4:
If we divide 15 by 2, we get 7 and a remainder of 1.
The next digit of our result is 7. 
Result so far: 4277.0
The remainder is 1 after subtracting 14 from 15.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 2

On to step 5:
2 goes into 16 8 times with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 42778.0
If we subtract 16 from 16, we get 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 2

Advancing to step 6:
The number 2 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 427780.0
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 7:
When dividing 0 by 2, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 427780.0
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.

Step 8:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 427780.0
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 427780.0, with a leftover of 0.0.
