417203 ÷ 2 
We want to figure out the number of times 417203 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
Subtracting 4 from 4 leaves us with 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 2

Step 2:
1 divided by 2 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 20.0
Subtract 0 from 1 to get 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 2

Advancing to step 3:
If we divide 17 by 2, we get 8 and a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 208.0
The remainder is 1 after subtracting 16 from 17.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 2

Let's proceed to step 4:
2 goes into 12 6 times with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 2086.0
Deduct 12 from 12 and we're left with 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 2

Going ahead to step 5:
The number 2 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 20860.0
Subtract 0 from 0 to get 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 2

Step 6:
2 can be fit into 3 1 times, resulting in a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 208601.0
Deduct 2 from 3 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
2 can be fit into 10 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 208601.5
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.

Step 8:
0 divided by 2 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 208601.5
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.

On to step 9:
2 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 208601.5
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 208601.5 with a remainder of 0.0.
