Let's divide 201929 by 1
The aim is to understand the frequency of 1 in 201929.

Going ahead to step 1:
1 can be fit into 2 2 times, resulting in a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 0 after subtracting 2 from 2.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 1

Advancing to step 2:
0 divided by 1 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
The remainder is 0 after subtracting 0 from 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 1

Moving on to step 3:
If we divide 1 by 1, we get 1 and a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 201.0
If we take 1 away from 1, we end up with 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 1

On to step 4:
The number 1 fits into 9 9 times, leaving a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 2019.0
If we subtract 9 from 9, we get 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 1

On to step 5:
The number 1 fits into 2 2 times, leaving a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 20192.0
Subtracting 2 from 2 leaves us with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 1

Advancing to step 6:
1 can be fit into 9 9 times, resulting in a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 201929.0
If we subtract 9 from 9, 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.

Step 7:
When dividing 0 by 1, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 201929.0
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:
The number 1 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 201929.0
Deduct 0 from 0 and we're left 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 201929.0, with a leftover of 0.0.
