Let's divide 221200 by 2
The aim is to understand the frequency of 2 in 221200.

Step 1:
The number 2 fits into 2 1 times, leaving 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.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 2

Advancing to step 2:
2 goes into 2 1 times with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
The remainder is 0 after subtracting 2 from 2.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 2

Advancing to step 3:
1 divided by 2 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 110.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 2

Going ahead to step 4:
If we divide 12 by 2, we get 6 and a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 1106.0
If we subtract 12 from 12, we get 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 2

Advancing to step 5:
The number 2 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 11060.0
The remainder is 0 after subtracting 0 from 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 2

Step 6:
If we divide 0 by 2, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 110600.0
If we subtract 0 from 0, we 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.

Going ahead to step 7:
0 divided by 2 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 110600.0
If we subtract 0 from 0, we 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.

Advancing to step 8:
If we divide 0 by 2, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 110600.0
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.

Our division results in 110600.0 with a remaining 0.0.
