30450830 ÷ 311 
The aim is to understand the frequency of 311 in 30450830.

Step 1:
When dividing 3 by 311, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 311

Moving on to step 2:
311 can be fit into 30 0 times, resulting in a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Fetch the next digit (4) from the dividend, attach it to 30 and continue: 304 / 311

Let's proceed to step 3:
If we divide 304 by 311, we get 0 and a remainder of 304.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 304, we end up with 304.
Grab the next digit (5) from the dividend, add it to 304, then carry on: 3045 / 311

Let's proceed to step 4:
When dividing 3045 by 311, we get 9 with a remainder of 246.
The next digit of our result is 9. 
Result so far: 9.0
Subtract 2799 from 3045 to get 246.
Include the next digit (0) from the dividend after 246, then repeat: 2460 / 311

On to step 5:
If we divide 2460 by 311, we get 7 and a remainder of 283.
Write down 7 as next digit of the result. 
Result so far: 97.0
Subtract 2177 from 2460 to get 283.
Fetch the next digit (8) from the dividend, attach it to 283 and continue: 2838 / 311

Step 6:
311 can be fit into 2838 9 times, resulting in a remainder of 39.
Use 9 as the next digit of our solution. 
Result so far: 979.0
The remainder is 39 after subtracting 2799 from 2838.
Include the next digit (3) from the dividend after 39, then repeat: 393 / 311

Let's proceed to step 7:
311 can be fit into 393 1 times, resulting in a remainder of 82.
The number 1 becomes the next digit in our result. 
Result so far: 9791.0
If we take 311 away from 393, we end up with 82.
Fetch the next digit (0) from the dividend, attach it to 82 and continue: 820 / 311

On to step 8:
311 goes into 820 2 times with a remainder of 198.
Put 2 as the next digit of the answer. 
Result so far: 97912.0
The remainder is 198 after subtracting 622 from 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Step 9:
If we divide 1980 by 311, we get 6 and a remainder of 114.
Record the quotient 6 as the next digit in the result. 
Result so far: 97912.6
If we take 1866 away from 1980, we end up with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

On to step 10:
If we divide 1140 by 311, we get 3 and a remainder of 207.
The next digit of our result is 3. 
Result so far: 97912.63
Deduct 933 from 1140 and we're left with 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Step 11:
2070 divided by 311 is 6 with a remainder of 204.
The next digit of our result is 6. 
Result so far: 97912.636
Subtracting 1866 from 2070 leaves us with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Let's proceed to step 12:
2040 divided by 311 is 6 with a remainder of 174.
Use 6 as the next digit of our solution. 
Result so far: 97912.6366
If we take 1866 away from 2040, we end up with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

In conclusion, the division gives 97912.6366 with a balance of 0.00174.
