We divide 203550 by 2
The aim is to understand the frequency of 2 in 203550.

On to step 1:
If we divide 2 by 2, we get 1 and a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 2 from 2 leaves us with 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 2

Going ahead to step 2:
0 divided by 2 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Deduct 0 from 0 and we're left with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 2

Step 3:
2 goes into 3 1 times with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 101.0
Deduct 2 from 3 and we're left with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 2

Let's proceed to step 4:
2 goes into 15 7 times with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 1017.0
Deduct 14 from 15 and we're left with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 2

Going ahead to step 5:
When dividing 15 by 2, we get 7 with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 10177.0
Deduct 14 from 15 and we're left with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 2

On to step 6:
The number 2 fits into 10 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 101775.0
Subtracting 10 from 10 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.

Advancing to step 7:
2 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 101775.0
The remainder is 0 after subtracting 0 from 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:
0 divided by 2 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 101775.0
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.

Our division results in 101775.0 with a remaining 0.0.
