Let's divide 203123 by 1
The aim is to understand the frequency of 1 in 203123.

Moving on to step 1:
When dividing 2 by 1, we get 2 with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 2 from 2, we get 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 1

Moving on to step 2:
The number 1 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 20.0
If we take 0 away from 0, we end up with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 1

Step 3:
1 can be fit into 3 3 times, resulting in a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 203.0
Subtracting 3 from 3 leaves us with 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 1

On to step 4:
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: 2031.0
The remainder is 0 after subtracting 1 from 1.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 1

Moving on to step 5:
If we divide 2 by 1, we get 2 and a remainder of 0.
The next digit of our result is 2. 
Result so far: 20312.0
Deduct 2 from 2 and we're left with 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 1

Let's proceed to step 6:
If we divide 3 by 1, we get 3 and a remainder of 0.
The next digit of our result is 3. 
Result so far: 203123.0
Deduct 3 from 3 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.

Advancing 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: 203123.0
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.

Let's proceed to step 8:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 203123.0
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.

In conclusion, the division gives 203123.0 with a balance of 0.0.
