We look at the division of 921107 by 2 
The aim is to understand the frequency of 2 in 921107.

Going ahead to step 1:
The number 2 fits into 9 4 times, leaving a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 8 away from 9, we end up with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 2

Going ahead to step 2:
12 divided by 2 is 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 46.0
If we take 12 away from 12, we end up with 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 2

Advancing to step 3:
2 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 460.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 2

Moving on to step 4:
The number 2 fits into 11 5 times, leaving a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 4605.0
Deduct 10 from 11 and we're left with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 2

Let's proceed to step 5:
The number 2 fits into 10 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 46055.0
The remainder is 0 after subtracting 10 from 10.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 2

Moving on to step 6:
The number 2 fits into 7 3 times, leaving a remainder of 1.
The next digit of our result is 3. 
Result so far: 460553.0
The remainder is 1 after subtracting 6 from 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
If we divide 10 by 2, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 460553.5
Subtract 10 from 10 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.

Step 8:
If we divide 0 by 2, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 460553.5
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.

On to step 9:
2 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 460553.5
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.

The quotient of the division is 460553.5, and the remainder is 0.0.
