Let's divide 583231 by 1
The aim is to understand the frequency of 1 in 583231.

Going ahead to step 1:
The number 1 fits into 5 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we subtract 5 from 5, we get 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 1

Step 2:
The number 1 fits into 8 8 times, leaving a remainder of 0.
The next digit of our result is 8. 
Result so far: 58.0
If we subtract 8 from 8, we get 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 1

Let's proceed to step 3:
The number 1 fits into 3 3 times, leaving a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 583.0
The remainder is 0 after subtracting 3 from 3.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 1

Advancing to step 4:
If we divide 2 by 1, we get 2 and a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 5832.0
Subtracting 2 from 2 leaves us with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 1

On to step 5:
The number 1 fits into 3 3 times, leaving a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 58323.0
Subtract 3 from 3 to get 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 1

Let's proceed to step 6:
1 goes into 1 1 times with a remainder of 0.
The next digit of our result is 1. 
Result so far: 583231.0
If we subtract 1 from 1, 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 7:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 583231.0
Subtract 0 from 0 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.

Moving on to step 8:
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: 583231.0
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.

Our division results in 583231.0 with a remaining 0.0.
