We look at the division of 722331 by 55 
The aim is to understand the frequency of 55 in 722331.

Let's proceed to step 1:
If we divide 7 by 55, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 55

Let's proceed to step 2:
55 goes into 72 1 times with a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 55 from 72 leaves us with 17.
Append the next digit (2) from the dividend to 17 and continue with: 172 / 55

Moving on to step 3:
55 can be fit into 172 3 times, resulting in a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we subtract 165 from 172, we get 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 55

Advancing to step 4:
73 divided by 55 is 1 with a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 131.0
Deduct 55 from 73 and we're left with 18.
Append the next digit (3) from the dividend to 18 and continue with: 183 / 55

Step 5:
183 divided by 55 is 3 with a remainder of 18.
Record the quotient 3 as the next digit in the result. 
Result so far: 1313.0
The remainder is 18 after subtracting 165 from 183.
Append the next digit (1) from the dividend to 18 and continue with: 181 / 55

Advancing to step 6:
The number 55 fits into 181 3 times, leaving a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 13133.0
Subtract 165 from 181 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 7:
When dividing 160 by 55, we get 2 with a remainder of 50.
Write down 2 as next digit of the result. 
Result so far: 13133.2
If we subtract 110 from 160, we 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.

On to step 8:
When dividing 500 by 55, we get 9 with a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 13133.29
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.

Moving on to step 9:
55 goes into 50 0 times with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 13133.29
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.

Going ahead to step 10:
500 divided by 55 is 9 with a remainder of 5.
The next digit of our result is 9. 
Result so far: 13133.2909
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.

Going ahead to step 11:
55 can be fit into 50 0 times, resulting in a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 13133.2909
Subtracting 0 from 50 leaves us 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.

On to step 12:
55 can be fit into 500 9 times, resulting in a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 13133.290909
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.

On to step 13:
55 can be fit into 50 0 times, resulting in a remainder of 50.
The next digit of our result is 0. 
Result so far: 13133.290909
If we subtract 0 from 50, we 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.

Step 14:
500 divided by 55 is 9 with a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 13133.29090909
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.

Our division results in 13133.29090909 with a remaining 5e-09.
