We're dividing 452124 by 1 
The aim is to understand the frequency of 1 in 452124.

Let's proceed 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
The remainder is 0 after subtracting 4 from 4.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 1

Moving on to step 2:
1 goes into 5 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 45.0
If we subtract 5 from 5, we get 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 1

Going ahead to step 3:
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: 452.0
The remainder is 0 after subtracting 2 from 2.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 1

Step 4:
If we divide 1 by 1, we get 1 and a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 4521.0
If we take 1 away from 1, we end up with 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 1

On to step 5:
When dividing 2 by 1, we get 2 with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 45212.0
If we subtract 2 from 2, we get 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 1

Moving on to step 6:
4 divided by 1 is 4 with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 452124.0
If we take 4 away from 4, 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.

Going ahead to step 7:
1 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 452124.0
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:
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: 452124.0
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.

After the division, we end up with 452124.0 and a remainder of 0.0.
