Let's divide 75514175 by 549
The aim is to understand the frequency of 549 in 75514175.

Going ahead to step 1:
If we divide 7 by 549, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 549

Moving on to step 2:
549 goes into 75 0 times with a remainder of 75.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 75 after subtracting 0 from 75.
Take the next digit (5) from the dividend and append it to 75, then repeat: 755 / 549

Step 3:
If we divide 755 by 549, we get 1 and a remainder of 206.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 206 after subtracting 549 from 755.
Take the next digit (1) from the dividend and append it to 206, then repeat: 2061 / 549

Advancing to step 4:
549 goes into 2061 3 times with a remainder of 414.
The next digit of our result is 3. 
Result so far: 13.0
If we take 1647 away from 2061, we end up with 414.
Bring next digit (4) of the dividend behind the 414 and repeat the process: 4144 / 549

Step 5:
4144 divided by 549 is 7 with a remainder of 301.
The number 7 becomes the next digit in our result. 
Result so far: 137.0
If we subtract 3843 from 4144, we get 301.
Take the next digit (1) from the dividend and append it to 301, then repeat: 3011 / 549

Let's proceed to step 6:
When dividing 3011 by 549, we get 5 with a remainder of 266.
Write down 5 as next digit of the result. 
Result so far: 1375.0
Deduct 2745 from 3011 and we're left with 266.
Bring next digit (7) of the dividend behind the 266 and repeat the process: 2667 / 549

Step 7:
549 can be fit into 2667 4 times, resulting in a remainder of 471.
Write down 4 as next digit of the result. 
Result so far: 13754.0
If we take 2196 away from 2667, we end up with 471.
Append the next digit (5) from the dividend to 471 and continue with: 4715 / 549

Let's proceed to step 8:
549 can be fit into 4715 8 times, resulting in a remainder of 323.
The number 8 becomes the next digit in our result. 
Result so far: 137548.0
Subtract 4392 from 4715 to get 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

Step 9:
When dividing 3230 by 549, we get 5 with a remainder of 485.
Put 5 as the next digit of the answer. 
Result so far: 137548.5
Deduct 2745 from 3230 and we're left with 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Going ahead to step 10:
The number 549 fits into 4850 8 times, leaving a remainder of 458.
The next digit of our result is 8. 
Result so far: 137548.58
If we take 4392 away from 4850, we end up with 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

Going ahead to step 11:
4580 divided by 549 is 8 with a remainder of 188.
The number 8 becomes the next digit in our result. 
Result so far: 137548.588
If we subtract 4392 from 4580, we get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

After the division, we end up with 137548.588 and a remainder of 0.0188.
