Let's divide 635804 by 1
The aim is to understand the frequency of 1 in 635804.

Going ahead to step 1:
If we divide 6 by 1, we get 6 and a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 6 away from 6, we end up with 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 1

Step 2:
1 can be fit into 3 3 times, resulting in a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 63.0
The remainder is 0 after subtracting 3 from 3.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 1

Step 3:
The number 1 fits into 5 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 635.0
If we take 5 away from 5, we end up with 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 1

Let's proceed to step 4:
If we divide 8 by 1, we get 8 and a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 6358.0
Subtract 8 from 8 to get 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 1

Going ahead to step 5:
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: 63580.0
The remainder is 0 after subtracting 0 from 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 1

Going ahead to step 6:
The number 1 fits into 4 4 times, leaving a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 635804.0
The remainder is 0 after subtracting 4 from 4.
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 7:
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: 635804.0
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:
0 divided by 1 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 635804.0
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.

Our division results in 635804.0 with a remaining 0.0.
