We look at the division of 781549 by 55 
The aim is to understand the frequency of 55 in 781549.

Advancing to step 1:
7 divided by 55 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 55

On to step 2:
78 divided by 55 is 1 with a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 55 from 78 leaves us with 23.
Append the next digit (1) from the dividend to 23 and continue with: 231 / 55

Moving on to step 3:
231 divided by 55 is 4 with a remainder of 11.
Write down 4 as next digit of the result. 
Result so far: 14.0
If we take 220 away from 231, we end up with 11.
Include the next digit (5) from the dividend after 11, then repeat: 115 / 55

Step 4:
The number 55 fits into 115 2 times, leaving a remainder of 5.
Use 2 as the next digit of our solution. 
Result so far: 142.0
Subtracting 110 from 115 leaves us with 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 55

Advancing to step 5:
54 divided by 55 is 0 with a remainder of 54.
The number 0 becomes the next digit in our result. 
Result so far: 1420.0
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

Let's proceed to step 6:
The number 55 fits into 549 9 times, leaving a remainder of 54.
The number 9 becomes the next digit in our result. 
Result so far: 14209.0
If we subtract 495 from 549, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 7:
55 goes into 540 9 times with a remainder of 45.
Put 9 as the next digit of the answer. 
Result so far: 14209.9
Subtract 495 from 540 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 8:
55 can be fit into 450 8 times, resulting in a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 14209.98
The remainder is 10 after subtracting 440 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 9:
55 goes into 100 1 times with a remainder of 45.
Use 1 as the next digit of our solution. 
Result so far: 14209.981
If we take 55 away from 100, we end up 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.

On to step 10:
55 can be fit into 450 8 times, resulting in a remainder of 10.
The next digit of our result is 8. 
Result so far: 14209.9818
Subtracting 440 from 450 leaves us 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.

On to step 11:
When dividing 100 by 55, we get 1 with a remainder of 45.
Record the quotient 1 as the next digit in the result. 
Result so far: 14209.98181
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.

On to step 12:
55 can be fit into 450 8 times, resulting in a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 14209.981818
If we take 440 away from 450, we end up 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.

On to step 13:
100 divided by 55 is 1 with a remainder of 45.
Put 1 as the next digit of the answer. 
Result so far: 14209.9818181
If we subtract 55 from 100, we get 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:
450 divided by 55 is 8 with a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 14209.98181818
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.

In conclusion, the division gives 14209.98181818 with a balance of 1e-08.
