We look at the division of 53868325 by 55 
The aim is to understand the frequency of 55 in 53868325.

On to step 1:
If we divide 5 by 55, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 55

On to step 2:
53 divided by 55 is 0 with a remainder of 53.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 53 and we're left with 53.
Append the next digit (8) from the dividend to 53 and continue with: 538 / 55

Going ahead to step 3:
538 divided by 55 is 9 with a remainder of 43.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we subtract 495 from 538, we get 43.
Fetch the next digit (6) from the dividend, attach it to 43 and continue: 436 / 55

Advancing to step 4:
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: 97.0
The remainder is 51 after subtracting 385 from 436.
Fetch the next digit (8) from the dividend, attach it to 51 and continue: 518 / 55

Moving on to step 5:
55 goes into 518 9 times with a remainder of 23.
The next digit of our result is 9. 
Result so far: 979.0
Subtract 495 from 518 to get 23.
Bring next digit (3) of the dividend behind the 23 and repeat the process: 233 / 55

On to step 6:
55 goes into 233 4 times with a remainder of 13.
Record the quotient 4 as the next digit in the result. 
Result so far: 9794.0
If we subtract 220 from 233, we get 13.
Bring next digit (2) of the dividend behind the 13 and repeat the process: 132 / 55

Advancing to step 7:
If we divide 132 by 55, we get 2 and a remainder of 22.
The next digit of our result is 2. 
Result so far: 97942.0
Subtract 110 from 132 to get 22.
Fetch the next digit (5) from the dividend, attach it to 22 and continue: 225 / 55

Advancing to step 8:
225 divided by 55 is 4 with a remainder of 5.
Use 4 as the next digit of our solution. 
Result so far: 979424.0
Subtract 220 from 225 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 9:
50 divided by 55 is 0 with a remainder of 50.
The next digit of our result is 0. 
Result so far: 979424.0
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 10:
55 can be fit into 500 9 times, resulting in a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 979424.09
If we take 495 away from 500, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 11:
When dividing 50 by 55, we get 0 with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 979424.09
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 12:
If we divide 500 by 55, we get 9 and a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 979424.0909
If we subtract 495 from 500, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 13:
50 divided by 55 is 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 979424.0909
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 14:
When dividing 500 by 55, we get 9 with a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 979424.090909
Deduct 495 from 500 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 15:
If we divide 50 by 55, we get 0 and a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 979424.090909
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 16:
500 divided by 55 is 9 with a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 979424.09090909
If we take 495 away from 500, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

After the division, we end up with 979424.09090909 and a remainder of 5e-09.
