We divide 184200 by 1
The aim is to understand the frequency of 1 in 184200.

Step 1:
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: 1.0
If we take 1 away from 1, we end up with 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 1

Going ahead to step 2:
8 divided by 1 is 8 with a remainder of 0.
The next digit of our result is 8. 
Result so far: 18.0
The remainder is 0 after subtracting 8 from 8.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 1

Let's proceed to step 3:
1 can be fit into 4 4 times, resulting in a remainder of 0.
The next digit of our result is 4. 
Result so far: 184.0
The remainder is 0 after subtracting 4 from 4.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 1

On to step 4:
The number 1 fits into 2 2 times, leaving a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 1842.0
If we subtract 2 from 2, we get 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 1

Let's proceed to step 5:
1 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 18420.0
If we subtract 0 from 0, we get 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 1

Advancing to step 6:
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: 184200.0
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.

Moving on to step 7:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 184200.0
If we subtract 0 from 0, 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 8:
When dividing 0 by 1, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 184200.0
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 result is 184200.0 with a remainder of 0.0.
