We're dividing 203457 by 2 
We want to figure out the number of times 203457 can be divided by 2.

Let's proceed to step 1:
The number 2 fits into 2 1 times, leaving a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 0 after subtracting 2 from 2.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 2

Going ahead to step 2:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10.0
The remainder is 0 after subtracting 0 from 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 2

Step 3:
When dividing 3 by 2, we get 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 101.0
Subtract 2 from 3 to get 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 2

Going ahead to step 4:
2 can be fit into 14 7 times, resulting in a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 1017.0
Subtract 14 from 14 to get 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 2

Let's proceed to step 5:
5 divided by 2 is 2 with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 10172.0
If we subtract 4 from 5, we get 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 2

Let's proceed to step 6:
The number 2 fits into 17 8 times, leaving a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 101728.0
Deduct 16 from 17 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.

On to step 7:
2 can be fit into 10 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 101728.5
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.

Let's proceed to step 8:
2 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 101728.5
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 9:
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: 101728.5
If we take 0 away from 0, 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.

The final result is 101728.5 with a remainder of 0.0.
