We divide 991252 by 2
The aim is to understand the frequency of 2 in 991252.

Step 1:
The number 2 fits into 9 4 times, leaving a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 8 from 9 to get 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 2

Step 2:
19 divided by 2 is 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 49.0
Subtracting 18 from 19 leaves us with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 2

Going ahead to step 3:
The number 2 fits into 11 5 times, leaving a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 495.0
Deduct 10 from 11 and we're left with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 2

Going ahead to step 4:
When dividing 12 by 2, we get 6 with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 4956.0
The remainder is 0 after subtracting 12 from 12.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 2

On to step 5:
2 can be fit into 5 2 times, resulting in a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 49562.0
If we subtract 4 from 5, we get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 2

On to step 6:
When dividing 12 by 2, we get 6 with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 495626.0
The remainder is 0 after subtracting 12 from 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on 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: 495626.0
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.

On to step 8:
The number 2 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 495626.0
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 495626.0 with a balance of 0.0.
