We're dividing 30522611 by 308 
The aim is to understand the frequency of 308 in 30522611.

Step 1:
308 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 308

Going ahead to step 2:
30 divided by 308 is 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Bring next digit (5) of the dividend behind the 30 and repeat the process: 305 / 308

Step 3:
If we divide 305 by 308, we get 0 and a remainder of 305.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 305 and we're left with 305.
Fetch the next digit (2) from the dividend, attach it to 305 and continue: 3052 / 308

Advancing to step 4:
308 can be fit into 3052 9 times, resulting in a remainder of 280.
Use 9 as the next digit of our solution. 
Result so far: 9.0
The remainder is 280 after subtracting 2772 from 3052.
Grab the next digit (2) from the dividend, add it to 280, then carry on: 2802 / 308

Moving on to step 5:
308 can be fit into 2802 9 times, resulting in a remainder of 30.
The number 9 becomes the next digit in our result. 
Result so far: 99.0
If we subtract 2772 from 2802, we get 30.
Bring next digit (6) of the dividend behind the 30 and repeat the process: 306 / 308

Going ahead to step 6:
306 divided by 308 is 0 with a remainder of 306.
Record the quotient 0 as the next digit in the result. 
Result so far: 990.0
If we subtract 0 from 306, we get 306.
Include the next digit (1) from the dividend after 306, then repeat: 3061 / 308

Moving on to step 7:
When dividing 3061 by 308, we get 9 with a remainder of 289.
The number 9 becomes the next digit in our result. 
Result so far: 9909.0
Deduct 2772 from 3061 and we're left with 289.
Append the next digit (1) from the dividend to 289 and continue with: 2891 / 308

Step 8:
308 goes into 2891 9 times with a remainder of 119.
Put 9 as the next digit of the answer. 
Result so far: 99099.0
If we take 2772 away from 2891, we end up with 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

On to step 9:
The number 308 fits into 1190 3 times, leaving a remainder of 266.
Put 3 as the next digit of the answer. 
Result so far: 99099.3
If we take 924 away from 1190, we end up with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

On to step 10:
308 can be fit into 2660 8 times, resulting in a remainder of 196.
Put 8 as the next digit of the answer. 
Result so far: 99099.38
Subtract 2464 from 2660 to get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Let's proceed to step 11:
308 can be fit into 1960 6 times, resulting in a remainder of 112.
Use 6 as the next digit of our solution. 
Result so far: 99099.386
If we subtract 1848 from 1960, we get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Advancing to step 12:
The number 308 fits into 1120 3 times, leaving a remainder of 196.
Use 3 as the next digit of our solution. 
Result so far: 99099.3863
If we subtract 924 from 1120, we get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

On to step 13:
1960 divided by 308 is 6 with a remainder of 112.
Use 6 as the next digit of our solution. 
Result so far: 99099.38636
Subtract 1848 from 1960 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Moving on to step 14:
When dividing 1120 by 308, we get 3 with a remainder of 196.
Record the quotient 3 as the next digit in the result. 
Result so far: 99099.386363
If we take 924 away from 1120, we end up with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

On to step 15:
When dividing 1960 by 308, we get 6 with a remainder of 112.
Use 6 as the next digit of our solution. 
Result so far: 99099.3863636
Deduct 1848 from 1960 and we're left with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Let's proceed to step 16:
308 can be fit into 1120 3 times, resulting in a remainder of 196.
Use 3 as the next digit of our solution. 
Result so far: 99099.38636363
Subtract 924 from 1120 to get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

The final result is 99099.38636363 with a remainder of 1.96e-07.
