857425 ÷ 2 
We're looking to find how many times 2 goes into 857425.

Moving on to step 1:
If we divide 8 by 2, we get 4 and a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 8 from 8 to get 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 2

Step 2:
5 divided by 2 is 2 with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 42.0
If we subtract 4 from 5, we get 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 2

Step 3:
When dividing 17 by 2, we get 8 with a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 428.0
If we subtract 16 from 17, we get 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 2

Let's proceed to step 4:
When dividing 14 by 2, we get 7 with a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 4287.0
If we take 14 away from 14, we end up with 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 2

Moving on to step 5:
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: 42871.0
The remainder is 0 after subtracting 2 from 2.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 2

Moving on to step 6:
5 divided by 2 is 2 with a remainder of 1.
The next digit of our result is 2. 
Result so far: 428712.0
Subtract 4 from 5 to get 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:
2 goes into 10 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 428712.5
Subtract 10 from 10 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.

Moving on to step 8:
If we divide 0 by 2, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 428712.5
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.

Going ahead to step 9:
The number 2 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 428712.5
The remainder is 0 after subtracting 0 from 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 428712.5 with a remainder of 0.0.
