We look at the division of 452035 by 1 
The aim is to understand the frequency of 1 in 452035.

Advancing to step 1:
If we divide 4 by 1, we get 4 and a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 4 away from 4, we end up with 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 1

Step 2:
1 goes into 5 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 45.0
Deduct 5 from 5 and we're left with 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 1

On to step 3:
1 goes into 2 2 times with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 452.0
Subtract 2 from 2 to get 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 1

On to step 4:
1 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 4520.0
Deduct 0 from 0 and we're left with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 1

Moving on to step 5:
The number 1 fits into 3 3 times, leaving a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 45203.0
Subtracting 3 from 3 leaves us with 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 1

Step 6:
If we divide 5 by 1, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 452035.0
Subtract 5 from 5 to 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.

Going ahead 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: 452035.0
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.

Advancing to step 8:
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: 452035.0
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.

The final outcome is 452035.0, with a leftover of 0.0.
