We look at the division of 484848 by 1 
The aim is to understand the frequency of 1 in 484848.

Going ahead to step 1:
4 divided by 1 is 4 with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 4 from 4 leaves us with 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 1

On to step 2:
The number 1 fits into 8 8 times, leaving a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 48.0
If we take 8 away from 8, we end up with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 1

On to step 3:
1 can be fit into 4 4 times, resulting in a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 484.0
Subtracting 4 from 4 leaves us with 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 1

Step 4:
If we divide 8 by 1, we get 8 and a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 4848.0
The remainder is 0 after subtracting 8 from 8.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 1

Advancing to step 5:
When dividing 4 by 1, we get 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 48484.0
If we subtract 4 from 4, we get 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 1

Advancing to step 6:
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: 484848.0
If we take 8 away from 8, we end up 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.

Step 7:
When dividing 0 by 1, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 484848.0
If we take 0 away from 0, we end up 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:
1 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 484848.0
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.

Our division results in 484848.0 with a remaining 0.0.
