We look at the division of 866524 by 55 
The aim is to understand the frequency of 55 in 866524.

Let's proceed to step 1:
If we divide 8 by 55, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 55

On to step 2:
When dividing 86 by 55, we get 1 with a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 55 away from 86, we end up with 31.
Take the next digit (6) from the dividend and append it to 31, then repeat: 316 / 55

Step 3:
316 divided by 55 is 5 with a remainder of 41.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtracting 275 from 316 leaves us with 41.
Include the next digit (5) from the dividend after 41, then repeat: 415 / 55

On to step 4:
If we divide 415 by 55, we get 7 and a remainder of 30.
Record the quotient 7 as the next digit in the result. 
Result so far: 157.0
Subtract 385 from 415 to get 30.
Include the next digit (2) from the dividend after 30, then repeat: 302 / 55

On to step 5:
The number 55 fits into 302 5 times, leaving a remainder of 27.
Record the quotient 5 as the next digit in the result. 
Result so far: 1575.0
Subtracting 275 from 302 leaves us with 27.
Bring next digit (4) of the dividend behind the 27 and repeat the process: 274 / 55

Step 6:
274 divided by 55 is 4 with a remainder of 54.
Write down 4 as next digit of the result. 
Result so far: 15754.0
Subtracting 220 from 274 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 7:
When dividing 540 by 55, we get 9 with a remainder of 45.
Use 9 as the next digit of our solution. 
Result so far: 15754.9
Subtracting 495 from 540 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 8:
55 goes into 450 8 times with a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 15754.98
Deduct 440 from 450 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 9:
The number 55 fits into 100 1 times, leaving a remainder of 45.
Use 1 as the next digit of our solution. 
Result so far: 15754.981
The remainder is 45 after subtracting 55 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 10:
The number 55 fits into 450 8 times, leaving a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 15754.9818
Subtract 440 from 450 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 11:
55 goes into 100 1 times with a remainder of 45.
The number 1 becomes the next digit in our result. 
Result so far: 15754.98181
Subtracting 55 from 100 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 12:
The number 55 fits into 450 8 times, leaving a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 15754.981818
Deduct 440 from 450 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 13:
55 goes into 100 1 times with a remainder of 45.
Write down 1 as next digit of the result. 
Result so far: 15754.9818181
Subtracting 55 from 100 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 14:
When dividing 450 by 55, we get 8 with a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 15754.98181818
Deduct 440 from 450 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The quotient of the division is 15754.98181818, and the remainder is 1e-08.
