We're dividing 217020 by 2 
The aim is to understand the frequency of 2 in 217020.

On to step 1:
When dividing 2 by 2, we get 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 2 from 2 to get 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 2

Step 2:
2 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtract 0 from 1 to get 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 2

Step 3:
17 divided by 2 is 8 with a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 108.0
The remainder is 1 after subtracting 16 from 17.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 2

Going ahead to step 4:
10 divided by 2 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 1085.0
Deduct 10 from 10 and we're left with 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 2

Let's proceed to step 5:
When dividing 2 by 2, we get 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 10851.0
The remainder is 0 after subtracting 2 from 2.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 2

Advancing to step 6:
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: 108510.0
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.

Let's proceed to step 7:
2 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 108510.0
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.

Let's proceed to step 8:
If we divide 0 by 2, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 108510.0
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.

In conclusion, the division gives 108510.0 with a balance of 0.0.
