We divide 4045 by 1
The aim is to understand the frequency of 1 in 4045.

Going ahead to step 1:
When dividing 4 by 1, we get 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 4 away from 4, we end up with 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 1

Let's proceed to step 2:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
If we take 0 away from 0, we end up with 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 1

Step 3:
The number 1 fits into 4 4 times, leaving a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 404.0
If we subtract 4 from 4, we get 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 1

Moving on to step 4:
5 divided by 1 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 4045.0
Subtracting 5 from 5 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.

On to step 5:
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: 4045.0
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.

Moving on to step 6:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 4045.0
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 4045.0 with a balance of 0.0.
