We look at the division of 308438 by 1 
The aim is to understand the frequency of 1 in 308438.

Moving on to step 1:
The number 1 fits into 3 3 times, leaving a remainder of 0.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 3 from 3 and we're left with 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 1

On to step 2:
1 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 30.0
The remainder is 0 after subtracting 0 from 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 1

Let's proceed to step 3:
1 goes into 8 8 times with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 308.0
The remainder is 0 after subtracting 8 from 8.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 1

Step 4:
When dividing 4 by 1, we get 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 3084.0
The remainder is 0 after subtracting 4 from 4.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 1

Advancing to step 5:
3 divided by 1 is 3 with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 30843.0
The remainder is 0 after subtracting 3 from 3.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 1

Moving on to step 6:
1 can be fit into 8 8 times, resulting in a remainder of 0.
The next digit of our result is 8. 
Result so far: 308438.0
Deduct 8 from 8 and we're left 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 7:
The number 1 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 308438.0
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.

Step 8:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 308438.0
Deduct 0 from 0 and we're left 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.

The final outcome is 308438.0, with a leftover of 0.0.
