We look at the division of 249986 by 2 
The aim is to understand the frequency of 2 in 249986.

Advancing to step 1:
When dividing 2 by 2, we get 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 2 from 2 to get 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 2

Going ahead to step 2:
When dividing 4 by 2, we get 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
The remainder is 0 after subtracting 4 from 4.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 2

Moving on to step 3:
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: 124.0
If we take 8 away from 9, 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:
2 can be fit into 19 9 times, resulting in a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 1249.0
Subtracting 18 from 19 leaves us with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 2

Going ahead to step 5:
2 can be fit into 18 9 times, resulting in a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 12499.0
Subtract 18 from 18 to get 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 2

Let's proceed to step 6:
6 divided by 2 is 3 with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 124993.0
Subtracting 6 from 6 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.

On to step 7:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 124993.0
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.

Step 8:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 124993.0
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.

After the division, we end up with 124993.0 and a remainder of 0.0.
