We look at the division of 921686 by 55 
The aim is to understand the frequency of 55 in 921686.

Going ahead to step 1:
When dividing 9 by 55, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (2) from the dividend, add it to 9, then carry on: 92 / 55

Moving on to step 2:
92 divided by 55 is 1 with a remainder of 37.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 55 from 92 to get 37.
Grab the next digit (1) from the dividend, add it to 37, then carry on: 371 / 55

Going ahead to step 3:
371 divided by 55 is 6 with a remainder of 41.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Subtract 330 from 371 to get 41.
Append the next digit (6) from the dividend to 41 and continue with: 416 / 55

Let's proceed to step 4:
If we divide 416 by 55, we get 7 and a remainder of 31.
The number 7 becomes the next digit in our result. 
Result so far: 167.0
Subtract 385 from 416 to get 31.
Bring next digit (8) of the dividend behind the 31 and repeat the process: 318 / 55

Going ahead to step 5:
When dividing 318 by 55, we get 5 with a remainder of 43.
The number 5 becomes the next digit in our result. 
Result so far: 1675.0
If we subtract 275 from 318, we get 43.
Fetch the next digit (6) from the dividend, attach it to 43 and continue: 436 / 55

Let's proceed to step 6:
The number 55 fits into 436 7 times, leaving a remainder of 51.
The number 7 becomes the next digit in our result. 
Result so far: 16757.0
Deduct 385 from 436 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 7:
510 divided by 55 is 9 with a remainder of 15.
The next digit of our result is 9. 
Result so far: 16757.9
Deduct 495 from 510 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 8:
If we divide 150 by 55, we get 2 and a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 16757.92
Subtracting 110 from 150 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 9:
400 divided by 55 is 7 with a remainder of 15.
Use 7 as the next digit of our solution. 
Result so far: 16757.927
The remainder is 15 after subtracting 385 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 10:
The number 55 fits into 150 2 times, leaving a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 16757.9272
Subtract 110 from 150 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 11:
When dividing 400 by 55, we get 7 with a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 16757.92727
Subtract 385 from 400 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 12:
If we divide 150 by 55, we get 2 and a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 16757.927272
Subtracting 110 from 150 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 13:
55 goes into 400 7 times with a remainder of 15.
Use 7 as the next digit of our solution. 
Result so far: 16757.9272727
The remainder is 15 after subtracting 385 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 14:
If we divide 150 by 55, we get 2 and a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 16757.92727272
Subtracting 110 from 150 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

In conclusion, the division gives 16757.92727272 with a balance of 4e-08.
