856278 ÷ 2 
We're looking to find how many times 2 goes into 856278.

Advancing to step 1:
2 goes into 8 4 times with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 8 away from 8, we end up with 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 2

Going ahead to step 2:
The number 2 fits into 5 2 times, leaving a remainder of 1.
The next digit of our result is 2. 
Result so far: 42.0
If we take 4 away from 5, we end up with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 2

On to step 3:
If we divide 16 by 2, we get 8 and a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 428.0
Deduct 16 from 16 and we're left with 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 2

Advancing to step 4:
If we divide 2 by 2, we get 1 and a remainder of 0.
The next digit of our result is 1. 
Result so far: 4281.0
Deduct 2 from 2 and we're left with 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 2

On to step 5:
7 divided by 2 is 3 with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 42813.0
Deduct 6 from 7 and we're left with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 2

Step 6:
When dividing 18 by 2, we get 9 with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 428139.0
If we take 18 away from 18, 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.

Advancing to step 7:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 428139.0
If we subtract 0 from 0, we 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.

Step 8:
The number 2 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 428139.0
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.

Our division results in 428139.0 with a remaining 0.0.
