488665 ÷ 1 
The aim is to understand the frequency of 1 in 488665.

Step 1:
The number 1 fits into 4 4 times, leaving a remainder of 0.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 4 from 4 to get 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 1

Moving on to step 2:
The number 1 fits into 8 8 times, leaving a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 48.0
Subtract 8 from 8 to get 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 1

Step 3:
8 divided by 1 is 8 with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 488.0
The remainder is 0 after subtracting 8 from 8.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 1

Going ahead to step 4:
1 can be fit into 6 6 times, resulting in a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 4886.0
Subtract 6 from 6 to get 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 1

Step 5:
1 can be fit into 6 6 times, resulting in a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 48866.0
The remainder is 0 after subtracting 6 from 6.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 1

Moving on to step 6:
The number 1 fits into 5 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 488665.0
If we subtract 5 from 5, 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.

Let's proceed to step 7:
1 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 488665.0
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.

Going ahead to step 8:
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: 488665.0
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.

The quotient of the division is 488665.0, and the remainder is 0.0.
