We're dividing 202099 by 1 
The aim is to understand the frequency of 1 in 202099.

On to step 1:
2 divided by 1 is 2 with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 2 away from 2, we end up with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 1

Moving on to step 2:
The number 1 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
If we subtract 0 from 0, we get 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 1

Going ahead to step 3:
1 goes into 2 2 times with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 202.0
If we subtract 2 from 2, we get 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 1

Going ahead to step 4:
If we divide 0 by 1, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 2020.0
The remainder is 0 after subtracting 0 from 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 1

On to step 5:
When dividing 9 by 1, we get 9 with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 20209.0
If we take 9 away from 9, we end up with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 1

Going ahead to step 6:
1 goes into 9 9 times with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 202099.0
Subtracting 9 from 9 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.

Let's proceed to step 7:
1 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 202099.0
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.

Going ahead to step 8:
1 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 202099.0
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.

The final outcome is 202099.0, with a leftover of 0.0.
