We look at the division of 998344 by 2 
The aim is to understand the frequency of 2 in 998344.

Moving on to step 1:
When dividing 9 by 2, we get 4 with a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 1 after subtracting 8 from 9.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 2

Moving on to step 2:
2 goes into 19 9 times with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 49.0
Deduct 18 from 19 and we're left with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 2

Let's proceed to step 3:
When dividing 18 by 2, we get 9 with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 499.0
Subtracting 18 from 18 leaves us with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 2

Moving on to step 4:
When dividing 3 by 2, we get 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 4991.0
The remainder is 1 after subtracting 2 from 3.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 2

Let's proceed to step 5:
14 divided by 2 is 7 with a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 49917.0
If we subtract 14 from 14, we get 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 2

Step 6:
When dividing 4 by 2, we get 2 with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 499172.0
Subtract 4 from 4 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.

Moving on to step 7:
2 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 499172.0
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.

Moving on to 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: 499172.0
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.

The final outcome is 499172.0, with a leftover of 0.0.
