We're dividing 203503 by 2 
The aim is to understand the frequency of 2 in 203503.

Step 1:
When dividing 2 by 2, we get 1 with a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 0 after subtracting 2 from 2.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 2

Going ahead to step 2:
If we divide 0 by 2, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
The remainder is 0 after subtracting 0 from 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 2

Let's proceed to step 3:
2 goes into 3 1 times with a remainder of 1.
The next digit of our result is 1. 
Result so far: 101.0
If we subtract 2 from 3, we get 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 2

Moving on to step 4:
15 divided by 2 is 7 with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 1017.0
If we take 14 away from 15, we end up with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 2

Let's proceed to step 5:
When dividing 10 by 2, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 10175.0
The remainder is 0 after subtracting 10 from 10.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 2

Moving on to step 6:
2 goes into 3 1 times with a remainder of 1.
The next digit of our result is 1. 
Result so far: 101751.0
Subtracting 2 from 3 leaves us 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.

Let's proceed to step 7:
When dividing 10 by 2, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 101751.5
The remainder is 0 after subtracting 10 from 10.
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:
2 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 101751.5
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.

Step 9:
When dividing 0 by 2, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 101751.5
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 101751.5 with a remainder of 0.0.
