We divide 399202 by 2
The aim is to understand the frequency of 2 in 399202.

Moving on to step 1:
If we divide 3 by 2, we get 1 and a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 2 away from 3, we end up with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 2

Let's proceed to step 2:
2 can be fit into 19 9 times, resulting in a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Deduct 18 from 19 and we're left with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 2

On to step 3:
19 divided by 2 is 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 199.0
Subtract 18 from 19 to get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 2

Advancing to step 4:
When dividing 12 by 2, we get 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 1996.0
Subtract 12 from 12 to get 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 2

On to step 5:
When dividing 0 by 2, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 19960.0
The remainder is 0 after subtracting 0 from 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 2

On to step 6:
If we divide 2 by 2, we get 1 and a remainder of 0.
The next digit of our result is 1. 
Result so far: 199601.0
If we subtract 2 from 2, 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.

Let's proceed to step 7:
If we divide 0 by 2, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 199601.0
If we take 0 away from 0, we end up 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 8:
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: 199601.0
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.

The final outcome is 199601.0, with a leftover of 0.0.
