609548 ÷ 1 
The aim is to understand the frequency of 1 in 609548.

Going ahead to step 1:
When dividing 6 by 1, we get 6 with 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.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 1

On to step 2:
0 divided by 1 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 60.0
The remainder is 0 after subtracting 0 from 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 1

Let's proceed to step 3:
The number 1 fits into 9 9 times, leaving 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.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 1

Moving on to step 4:
1 goes into 5 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 6095.0
The remainder is 0 after subtracting 5 from 5.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 1

On to step 5:
If we divide 4 by 1, we get 4 and a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 60954.0
The remainder is 0 after subtracting 4 from 4.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 1

Step 6:
If we divide 8 by 1, we get 8 and a remainder of 0.
The next digit of our result is 8. 
Result so far: 609548.0
Subtract 8 from 8 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.

Advancing to step 7:
When dividing 0 by 1, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 609548.0
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.

Advancing to step 8:
0 divided by 1 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 609548.0
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 outcome is 609548.0, with a leftover of 0.0.
