Let's divide 163398 by 2
The aim is to understand the frequency of 2 in 163398.

Step 1:
2 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 2

On to step 2:
When dividing 16 by 2, we get 8 with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 16 from 16, we get 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 2

On to step 3:
2 goes into 3 1 times with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 81.0
The remainder is 1 after subtracting 2 from 3.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 2

Moving on to step 4:
The number 2 fits into 13 6 times, leaving a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 816.0
Deduct 12 from 13 and we're left with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 2

Step 5:
2 can be fit into 19 9 times, resulting in a remainder of 1.
The next digit of our result is 9. 
Result so far: 8169.0
The remainder is 1 after subtracting 18 from 19.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 2

Let's proceed to step 6:
2 goes into 18 9 times with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 81699.0
Subtracting 18 from 18 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.

Going ahead to step 7:
The number 2 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 81699.0
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.

Moving on to step 8:
0 divided by 2 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 81699.0
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.

In conclusion, the division gives 81699.0 with a balance of 0.0.
