We divide 51208101 by 549
The aim is to understand the frequency of 549 in 51208101.

Advancing to step 1:
If we divide 5 by 549, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 549

Step 2:
51 divided by 549 is 0 with a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Fetch the next digit (2) from the dividend, attach it to 51 and continue: 512 / 549

Going ahead to step 3:
549 goes into 512 0 times with a remainder of 512.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 512 leaves us with 512.
Fetch the next digit (0) from the dividend, attach it to 512 and continue: 5120 / 549

On to step 4:
549 goes into 5120 9 times with a remainder of 179.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtract 4941 from 5120 to get 179.
Append the next digit (8) from the dividend to 179 and continue with: 1798 / 549

Moving on to step 5:
1798 divided by 549 is 3 with a remainder of 151.
The next digit of our result is 3. 
Result so far: 93.0
The remainder is 151 after subtracting 1647 from 1798.
Fetch the next digit (1) from the dividend, attach it to 151 and continue: 1511 / 549

Let's proceed to step 6:
If we divide 1511 by 549, we get 2 and a remainder of 413.
Put 2 as the next digit of the answer. 
Result so far: 932.0
Subtract 1098 from 1511 to get 413.
Include the next digit (0) from the dividend after 413, then repeat: 4130 / 549

On to step 7:
549 can be fit into 4130 7 times, resulting in a remainder of 287.
The next digit of our result is 7. 
Result so far: 9327.0
Subtract 3843 from 4130 to get 287.
Take the next digit (1) from the dividend and append it to 287, then repeat: 2871 / 549

Let's proceed to step 8:
If we divide 2871 by 549, we get 5 and a remainder of 126.
The next digit of our result is 5. 
Result so far: 93275.0
The remainder is 126 after subtracting 2745 from 2871.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Going ahead to step 9:
The number 549 fits into 1260 2 times, leaving a remainder of 162.
Write down 2 as next digit of the result. 
Result so far: 93275.2
Deduct 1098 from 1260 and we're left with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Going ahead to step 10:
549 can be fit into 1620 2 times, resulting in a remainder of 522.
The next digit of our result is 2. 
Result so far: 93275.22
The remainder is 522 after subtracting 1098 from 1620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

Our division results in 93275.22 with a remaining 0.522.
