We look at the division of 287690 by 55 
The aim is to understand the frequency of 55 in 287690.

Let's proceed to step 1:
55 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 55

Let's proceed to step 2:
When dividing 28 by 55, we get 0 with a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 28 and we're left with 28.
Include the next digit (7) from the dividend after 28, then repeat: 287 / 55

Advancing to step 3:
If we divide 287 by 55, we get 5 and a remainder of 12.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 275 from 287 and we're left with 12.
Grab the next digit (6) from the dividend, add it to 12, then carry on: 126 / 55

Let's proceed to step 4:
55 goes into 126 2 times with a remainder of 16.
The next digit of our result is 2. 
Result so far: 52.0
The remainder is 16 after subtracting 110 from 126.
Bring next digit (9) of the dividend behind the 16 and repeat the process: 169 / 55

Step 5:
55 can be fit into 169 3 times, resulting in a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 523.0
Deduct 165 from 169 and we're left with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 55

Advancing to step 6:
If we divide 40 by 55, we get 0 and a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 5230.0
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 7:
400 divided by 55 is 7 with a remainder of 15.
The number 7 becomes the next digit in our result. 
Result so far: 5230.7
If we subtract 385 from 400, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 8:
If we divide 150 by 55, we get 2 and a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 5230.72
Subtract 110 from 150 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
55 goes into 400 7 times with a remainder of 15.
The number 7 becomes the next digit in our result. 
Result so far: 5230.727
Subtracting 385 from 400 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 10:
55 can be fit into 150 2 times, resulting in a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 5230.7272
The remainder is 40 after subtracting 110 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 11:
55 can be fit into 400 7 times, resulting in a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 5230.72727
If we subtract 385 from 400, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 12:
55 goes into 150 2 times with a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 5230.727272
If we take 110 away from 150, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 13:
When dividing 400 by 55, we get 7 with a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 5230.7272727
Subtracting 385 from 400 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 14:
When dividing 150 by 55, we get 2 with a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 5230.72727272
Subtracting 110 from 150 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final outcome is 5230.72727272, with a leftover of 4e-08.
