We look at the division of 817588 by 55 
The aim is to understand the frequency of 55 in 817588.

On to step 1:
55 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 55

Step 2:
81 divided by 55 is 1 with a remainder of 26.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 26 after subtracting 55 from 81.
Grab the next digit (7) from the dividend, add it to 26, then carry on: 267 / 55

On to step 3:
The number 55 fits into 267 4 times, leaving a remainder of 47.
The next digit of our result is 4. 
Result so far: 14.0
If we subtract 220 from 267, we get 47.
Bring next digit (5) of the dividend behind the 47 and repeat the process: 475 / 55

Going ahead to step 4:
If we divide 475 by 55, we get 8 and a remainder of 35.
The next digit of our result is 8. 
Result so far: 148.0
Deduct 440 from 475 and we're left with 35.
Take the next digit (8) from the dividend and append it to 35, then repeat: 358 / 55

Moving on to step 5:
55 goes into 358 6 times with a remainder of 28.
The number 6 becomes the next digit in our result. 
Result so far: 1486.0
If we subtract 330 from 358, we get 28.
Grab the next digit (8) from the dividend, add it to 28, then carry on: 288 / 55

Going ahead to step 6:
The number 55 fits into 288 5 times, leaving a remainder of 13.
The next digit of our result is 5. 
Result so far: 14865.0
If we take 275 away from 288, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 7:
55 can be fit into 130 2 times, resulting in a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 14865.2
Deduct 110 from 130 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
55 goes into 200 3 times with a remainder of 35.
Write down 3 as next digit of the result. 
Result so far: 14865.23
If we subtract 165 from 200, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 9:
The number 55 fits into 350 6 times, leaving a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 14865.236
If we subtract 330 from 350, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 10:
55 goes into 200 3 times with a remainder of 35.
Use 3 as the next digit of our solution. 
Result so far: 14865.2363
Deduct 165 from 200 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 11:
350 divided by 55 is 6 with a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 14865.23636
Subtracting 330 from 350 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 12:
If we divide 200 by 55, we get 3 and a remainder of 35.
Use 3 as the next digit of our solution. 
Result so far: 14865.236363
Deduct 165 from 200 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 13:
55 goes into 350 6 times with a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 14865.2363636
If we take 330 away from 350, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 14:
55 can be fit into 200 3 times, resulting in a remainder of 35.
Write down 3 as next digit of the result. 
Result so far: 14865.23636363
Subtracting 165 from 200 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

After the division, we end up with 14865.23636363 and a remainder of 3.5e-08.
