We look at the division of 394991 by 2 
The aim is to understand the frequency of 2 in 394991.

Step 1:
3 divided by 2 is 1 with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 1 after subtracting 2 from 3.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 2

Going ahead to step 2:
2 goes into 19 9 times with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Subtracting 18 from 19 leaves us with 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 2

Moving on to step 3:
14 divided by 2 is 7 with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 197.0
Deduct 14 from 14 and we're left with 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 2

Going ahead to step 4:
2 can be fit into 9 4 times, resulting in a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 1974.0
Subtracting 8 from 9 leaves us with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 2

Advancing to step 5:
19 divided by 2 is 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 19749.0
If we take 18 away from 19, we end up with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 2

Step 6:
11 divided by 2 is 5 with a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 197495.0
If we subtract 10 from 11, we get 1.
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:
The number 2 fits into 10 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 197495.5
If we subtract 10 from 10, 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.

Moving on to step 8:
0 divided by 2 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 197495.5
Subtracting 0 from 0 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 9:
2 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 197495.5
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 197495.5 with a balance of 0.0.
