We look at the division of 30799690 by 549 
The aim is to understand the frequency of 549 in 30799690.

Step 1:
When dividing 3 by 549, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 549

On to step 2:
549 goes into 30 0 times with a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Include the next digit (7) from the dividend after 30, then repeat: 307 / 549

Let's proceed to step 3:
549 goes into 307 0 times with a remainder of 307.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 307 to get 307.
Append the next digit (9) from the dividend to 307 and continue with: 3079 / 549

Going ahead to step 4:
549 goes into 3079 5 times with a remainder of 334.
Put 5 as the next digit of the answer. 
Result so far: 5.0
The remainder is 334 after subtracting 2745 from 3079.
Grab the next digit (9) from the dividend, add it to 334, then carry on: 3349 / 549

Going ahead to step 5:
549 goes into 3349 6 times with a remainder of 55.
Put 6 as the next digit of the answer. 
Result so far: 56.0
Subtracting 3294 from 3349 leaves us with 55.
Bring next digit (6) of the dividend behind the 55 and repeat the process: 556 / 549

Going ahead to step 6:
549 goes into 556 1 times with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 561.0
Deduct 549 from 556 and we're left with 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 549

On to step 7:
When dividing 79 by 549, we get 0 with a remainder of 79.
The number 0 becomes the next digit in our result. 
Result so far: 5610.0
Subtract 0 from 79 to get 79.
Bring next digit (0) of the dividend behind the 79 and repeat the process: 790 / 549

Moving on to step 8:
549 can be fit into 790 1 times, resulting in a remainder of 241.
Use 1 as the next digit of our solution. 
Result so far: 56101.0
Subtracting 549 from 790 leaves us with 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

Moving on to step 9:
549 can be fit into 2410 4 times, resulting in a remainder of 214.
The number 4 becomes the next digit in our result. 
Result so far: 56101.4
The remainder is 214 after subtracting 2196 from 2410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Going ahead to step 10:
The number 549 fits into 2140 3 times, leaving a remainder of 493.
The next digit of our result is 3. 
Result so far: 56101.43
Deduct 1647 from 2140 and we're left with 493.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4930, and continue the process.

On to step 11:
If we divide 4930 by 549, we get 8 and a remainder of 538.
The number 8 becomes the next digit in our result. 
Result so far: 56101.438
The remainder is 538 after subtracting 4392 from 4930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

Moving on to step 12:
The number 549 fits into 5380 9 times, leaving a remainder of 439.
Use 9 as the next digit of our solution. 
Result so far: 56101.4389
Subtracting 4941 from 5380 leaves us with 439.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4390, and continue the process.

Advancing to step 13:
The number 549 fits into 4390 7 times, leaving a remainder of 547.
The number 7 becomes the next digit in our result. 
Result so far: 56101.43897
Deduct 3843 from 4390 and we're left with 547.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5470, and continue the process.

Step 14:
549 goes into 5470 9 times with a remainder of 529.
The next digit of our result is 9. 
Result so far: 56101.438979
The remainder is 529 after subtracting 4941 from 5470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5290, and continue the process.

On to step 15:
549 goes into 5290 9 times with a remainder of 349.
The next digit of our result is 9. 
Result so far: 56101.4389799
The remainder is 349 after subtracting 4941 from 5290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

The final result is 56101.4389799 with a remainder of 3.49e-06.
