549876 ÷ 55 
The aim is to understand the frequency of 55 in 549876.

Going ahead to step 1:
55 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 55

Going ahead to step 2:
55 can be fit into 54 0 times, resulting in a remainder of 54.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 54, we end up with 54.
Include the next digit (9) from the dividend after 54, then repeat: 549 / 55

Step 3:
549 divided by 55 is 9 with a remainder of 54.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 495 away from 549, we end up with 54.
Bring next digit (8) of the dividend behind the 54 and repeat the process: 548 / 55

Let's proceed to step 4:
When dividing 548 by 55, we get 9 with a remainder of 53.
Record the quotient 9 as the next digit in the result. 
Result so far: 99.0
Subtract 495 from 548 to get 53.
Append the next digit (7) from the dividend to 53 and continue with: 537 / 55

Going ahead to step 5:
55 goes into 537 9 times with a remainder of 42.
Write down 9 as next digit of the result. 
Result so far: 999.0
Deduct 495 from 537 and we're left with 42.
Take the next digit (6) from the dividend and append it to 42, then repeat: 426 / 55

Going ahead to step 6:
55 goes into 426 7 times with a remainder of 41.
Record the quotient 7 as the next digit in the result. 
Result so far: 9997.0
Subtract 385 from 426 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 7:
410 divided by 55 is 7 with a remainder of 25.
Write down 7 as next digit of the result. 
Result so far: 9997.7
If we subtract 385 from 410, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 8:
55 goes into 250 4 times with a remainder of 30.
The next digit of our result is 4. 
Result so far: 9997.74
Subtract 220 from 250 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 9:
The number 55 fits into 300 5 times, leaving a remainder of 25.
The next digit of our result is 5. 
Result so far: 9997.745
The remainder is 25 after subtracting 275 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 10:
When dividing 250 by 55, we get 4 with a remainder of 30.
The next digit of our result is 4. 
Result so far: 9997.7454
Subtract 220 from 250 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 11:
300 divided by 55 is 5 with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 9997.74545
Subtract 275 from 300 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 12:
250 divided by 55 is 4 with a remainder of 30.
Put 4 as the next digit of the answer. 
Result so far: 9997.745454
Deduct 220 from 250 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 13:
If we divide 300 by 55, we get 5 and a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 9997.7454545
Subtracting 275 from 300 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 14:
If we divide 250 by 55, we get 4 and a remainder of 30.
The next digit of our result is 4. 
Result so far: 9997.74545454
If we subtract 220 from 250, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final outcome is 9997.74545454, with a leftover of 3e-08.
