We look at the division of 856741 by 2 
We're looking to find how many times 2 goes into 856741.

On to step 1:
2 goes into 8 4 times with a remainder of 0.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 8 from 8 leaves us with 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 2

Going ahead to step 2:
2 goes into 5 2 times with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 42.0
Subtract 4 from 5 to get 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 2

Step 3:
2 goes into 16 8 times with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 428.0
Deduct 16 from 16 and we're left with 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 2

Step 4:
2 goes into 7 3 times with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 4283.0
If we subtract 6 from 7, we get 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 2

Moving on to step 5:
The number 2 fits into 14 7 times, leaving a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 42837.0
If we take 14 away from 14, we end up with 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 2

Let's proceed to step 6:
If we divide 1 by 2, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 428370.0
Subtracting 0 from 1 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
If we divide 10 by 2, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 428370.5
The remainder is 0 after subtracting 10 from 10.
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:
When dividing 0 by 2, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 428370.5
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 9:
If we divide 0 by 2, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 428370.5
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.

Our division results in 428370.5 with a remaining 0.0.
