We look at the division of 428474 by 2 
Let's see how many times 2 fits into 428474.

On to step 1:
2 goes into 4 2 times with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 4 from 4 and we're left with 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 2

Going ahead to step 2:
2 can be fit into 2 1 times, resulting in a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
If we subtract 2 from 2, we get 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 2

Step 3:
2 goes into 8 4 times with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 214.0
Deduct 8 from 8 and we're left with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 2

Advancing to step 4:
If we divide 4 by 2, we get 2 and a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 2142.0
The remainder is 0 after subtracting 4 from 4.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 2

On to step 5:
2 goes into 7 3 times with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 21423.0
The remainder is 1 after subtracting 6 from 7.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 2

Advancing to step 6:
2 goes into 14 7 times with a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 214237.0
Deduct 14 from 14 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.

Going ahead to step 7:
2 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 214237.0
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.

Moving on to step 8:
0 divided by 2 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 214237.0
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.

The final result is 214237.0 with a remainder of 0.0.
