We look at the division of 281090 by 55 
The aim is to understand the frequency of 55 in 281090.

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
Subtract 0 from 2 to get 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 55

On 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
If we take 0 away from 28, we end up with 28.
Bring next digit (1) of the dividend behind the 28 and repeat the process: 281 / 55

Going ahead to step 3:
When dividing 281 by 55, we get 5 with a remainder of 6.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 275 from 281 leaves us with 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 55

On to step 4:
55 goes into 60 1 times with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 51.0
Subtracting 55 from 60 leaves us with 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 55

Let's proceed to step 5:
When dividing 59 by 55, we get 1 with a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 511.0
The remainder is 4 after subtracting 55 from 59.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 55

Moving on to step 6:
The number 55 fits into 40 0 times, leaving a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 5110.0
If we take 0 away from 40, 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.

On to step 7:
The number 55 fits into 400 7 times, leaving a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 5110.7
The remainder is 15 after subtracting 385 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 8:
55 goes into 150 2 times with a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 5110.72
If we subtract 110 from 150, we 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.

Going ahead to step 9:
55 can be fit into 400 7 times, resulting in a remainder of 15.
Use 7 as the next digit of our solution. 
Result so far: 5110.727
Deduct 385 from 400 and we're left 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.

Going ahead to step 10:
If we divide 150 by 55, we get 2 and a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 5110.7272
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.

Step 11:
If we divide 400 by 55, we get 7 and a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 5110.72727
Deduct 385 from 400 and we're left 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.

Step 12:
The number 55 fits into 150 2 times, leaving a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 5110.727272
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.

Step 13:
55 goes into 400 7 times with a remainder of 15.
The number 7 becomes the next digit in our result. 
Result so far: 5110.7272727
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.
The number 2 becomes the next digit in our result. 
Result so far: 5110.72727272
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.

The final result is 5110.72727272 with a remainder of 4e-08.
