We divide 404217 by 2
We want to figure out the number of times 404217 can be divided by 2.

On to step 1:
2 can be fit into 4 2 times, resulting in a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 4 from 4, we get 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 2

Step 2:
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: 20.0
If we subtract 0 from 0, we get 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 2

Going ahead to step 3:
2 goes into 4 2 times with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 202.0
If we take 4 away from 4, we end up with 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 2

Going ahead to step 4:
2 can be fit into 2 1 times, resulting in a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 2021.0
Subtract 2 from 2 to get 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 2

Going ahead to step 5:
1 divided by 2 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 20210.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 2

On to step 6:
2 goes into 17 8 times with a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 202108.0
The remainder is 1 after subtracting 16 from 17.
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.
Record the quotient 5 as the next digit in the result. 
Result so far: 202108.5
If we take 10 away from 10, we end up 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 8:
2 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 202108.5
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.

Let's proceed to step 9:
2 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 202108.5
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.

The final outcome is 202108.5, with a leftover of 0.0.
