Let's divide 609735 by 1
The aim is to understand the frequency of 1 in 609735.

Advancing to step 1:
The number 1 fits into 6 6 times, leaving a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtract 6 from 6 to get 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 1

Advancing to step 2:
If we divide 0 by 1, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 60.0
If we take 0 away from 0, we end up with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 1

Step 3:
9 divided by 1 is 9 with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 609.0
Subtracting 9 from 9 leaves us with 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 1

Advancing to step 4:
1 can be fit into 7 7 times, resulting in a remainder of 0.
The next digit of our result is 7. 
Result so far: 6097.0
If we take 7 away from 7, we end up with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 1

On to step 5:
3 divided by 1 is 3 with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 60973.0
If we take 3 away from 3, we end up with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 1

Advancing to step 6:
When dividing 5 by 1, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 609735.0
The remainder is 0 after subtracting 5 from 5.
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:
If we divide 0 by 1, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 609735.0
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.

Going ahead to step 8:
0 divided by 1 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 609735.0
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.

The final result is 609735.0 with a remainder of 0.0.
