Let's divide 459210 by 2
We're looking to find how many times 2 goes into 459210.

Going ahead to step 1:
When dividing 4 by 2, we get 2 with a remainder of 0.
The next digit of our result is 2. 
Result so far: 2.0
If we take 4 away from 4, we end up 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.
Use 2 as the next digit of our solution. 
Result so far: 22.0
Deduct 4 from 5 and we're left with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 2

On to step 3:
If we divide 19 by 2, we get 9 and a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 229.0
Subtract 18 from 19 to get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 2

Let's proceed to step 4:
2 can be fit into 12 6 times, resulting in a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 2296.0
Subtracting 12 from 12 leaves us with 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 2

Moving on to step 5:
2 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 22960.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 2

Moving on to step 6:
10 divided by 2 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 229605.0
Deduct 10 from 10 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.

Advancing to step 7:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 229605.0
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.

On to step 8:
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: 229605.0
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.

After the division, we end up with 229605.0 and a remainder of 0.0.
