We look at the division of 428512 by 2 
We want to divide 428512 by 2.

Let's proceed to step 1:
The number 2 fits into 4 2 times, leaving a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 4 away from 4, we end up with 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 2

Let's proceed to step 2:
2 goes into 2 1 times with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
Subtract 2 from 2 to get 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 2

Let's proceed to step 3:
The number 2 fits into 8 4 times, leaving a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 214.0
If we subtract 8 from 8, we get 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 2

On to step 4:
2 can be fit into 5 2 times, resulting in a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 2142.0
Deduct 4 from 5 and we're left with 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 2

Let's proceed to step 5:
11 divided by 2 is 5 with a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 21425.0
Deduct 10 from 11 and we're left with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 2

Let's proceed to step 6:
2 can be fit into 12 6 times, resulting in a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 214256.0
The remainder is 0 after subtracting 12 from 12.
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 7:
When dividing 0 by 2, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 214256.0
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.

Advancing to step 8:
2 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 214256.0
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.

Our division results in 214256.0 with a remaining 0.0.
