We're dividing 30308 by 1 
The aim is to understand the frequency of 1 in 30308.

Advancing to step 1:
1 goes into 3 3 times with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 3 from 3 leaves us with 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 1

Going ahead to step 2:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 30.0
If we subtract 0 from 0, we get 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 1

Going ahead to step 3:
1 can be fit into 3 3 times, resulting in a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 303.0
Subtract 3 from 3 to get 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 1

Advancing to step 4:
1 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 3030.0
The remainder is 0 after subtracting 0 from 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 1

Step 5:
The number 1 fits into 8 8 times, leaving a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 30308.0
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 6:
1 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 30308.0
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.

On to step 7:
If we divide 0 by 1, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 30308.0
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 result is 30308.0 with a remainder of 0.0.
