Let's divide 425420 by 2
We want to figure out the number of times 425420 can be divided by 2.

Step 1:
2 can be fit into 4 2 times, resulting in a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 4 from 4 and we're left with 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 2

Going ahead to step 2:
If we divide 2 by 2, we get 1 and a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 21.0
Deduct 2 from 2 and we're left with 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 2

Going ahead to step 3:
2 goes into 5 2 times with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 212.0
Deduct 4 from 5 and we're left with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 2

Let's proceed to step 4:
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: 2127.0
Deduct 14 from 14 and we're left with 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 2

Advancing to step 5:
If we divide 2 by 2, we get 1 and a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 21271.0
If we take 2 away from 2, we end up with 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 2

Let's proceed to step 6:
2 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 212710.0
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.

Let's proceed to step 7:
0 divided by 2 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 212710.0
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.

On to step 8:
0 divided by 2 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 212710.0
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.

After the division, we end up with 212710.0 and a remainder of 0.0.
