Let's divide 427944 by 2
The aim is to understand the frequency of 2 in 427944.

Step 1:
4 divided by 2 is 2 with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 4 from 4 leaves us with 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 2

Going ahead to step 2:
The number 2 fits into 2 1 times, leaving a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 21.0
Subtract 2 from 2 to get 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 2

Step 3:
7 divided by 2 is 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 213.0
If we take 6 away from 7, we end up with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 2

Let's proceed to step 4:
The number 2 fits into 19 9 times, leaving a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 2139.0
The remainder is 1 after subtracting 18 from 19.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 2

Advancing to step 5:
The number 2 fits into 14 7 times, leaving a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 21397.0
If we take 14 away from 14, we end up with 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 2

Let's proceed to step 6:
If we divide 4 by 2, we get 2 and a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 213972.0
If we subtract 4 from 4, 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 7:
The number 2 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 213972.0
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.
The number 0 becomes the next digit in our result. 
Result so far: 213972.0
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 213972.0 with a remaining 0.0.
