We look at the division of 727691 by 55 
The aim is to understand the frequency of 55 in 727691.

Step 1:
55 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 55

Going ahead to step 2:
When dividing 72 by 55, we get 1 with a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 55 from 72, we get 17.
Include the next digit (7) from the dividend after 17, then repeat: 177 / 55

Step 3:
The number 55 fits into 177 3 times, leaving a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Deduct 165 from 177 and we're left with 12.
Append the next digit (6) from the dividend to 12 and continue with: 126 / 55

Step 4:
The number 55 fits into 126 2 times, leaving a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 132.0
Deduct 110 from 126 and we're left with 16.
Grab the next digit (9) from the dividend, add it to 16, then carry on: 169 / 55

On to step 5:
If we divide 169 by 55, we get 3 and a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 1323.0
Subtracting 165 from 169 leaves us with 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 55

On to step 6:
If we divide 41 by 55, we get 0 and a remainder of 41.
The number 0 becomes the next digit in our result. 
Result so far: 13230.0
The remainder is 41 after subtracting 0 from 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 7:
55 can be fit into 410 7 times, resulting in a remainder of 25.
Put 7 as the next digit of the answer. 
Result so far: 13230.7
The remainder is 25 after subtracting 385 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 8:
55 can be fit into 250 4 times, resulting in a remainder of 30.
Write down 4 as next digit of the result. 
Result so far: 13230.74
If we subtract 220 from 250, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 9:
The number 55 fits into 300 5 times, leaving a remainder of 25.
The next digit of our result is 5. 
Result so far: 13230.745
If we subtract 275 from 300, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 10:
55 can be fit into 250 4 times, resulting in a remainder of 30.
Record the quotient 4 as the next digit in the result. 
Result so far: 13230.7454
Subtracting 220 from 250 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 11:
When dividing 300 by 55, we get 5 with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 13230.74545
If we subtract 275 from 300, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 12:
55 can be fit into 250 4 times, resulting in a remainder of 30.
Record the quotient 4 as the next digit in the result. 
Result so far: 13230.745454
If we subtract 220 from 250, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 13:
55 goes into 300 5 times with a remainder of 25.
The next digit of our result is 5. 
Result so far: 13230.7454545
Deduct 275 from 300 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 14:
55 can be fit into 250 4 times, resulting in a remainder of 30.
The next digit of our result is 4. 
Result so far: 13230.74545454
Deduct 220 from 250 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The quotient of the division is 13230.74545454, and the remainder is 3e-08.
