280461 ÷ 55 
The aim is to understand the frequency of 55 in 280461.

Going ahead to step 1:
When dividing 2 by 55, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 55

On to step 2:
28 divided by 55 is 0 with a remainder of 28.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 28 to get 28.
Fetch the next digit (0) from the dividend, attach it to 28 and continue: 280 / 55

Advancing to step 3:
55 can be fit into 280 5 times, resulting in a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 275 from 280 and we're left with 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 55

On to step 4:
If we divide 54 by 55, we get 0 and a remainder of 54.
Write down 0 as next digit of the result. 
Result so far: 50.0
The remainder is 54 after subtracting 0 from 54.
Include the next digit (6) from the dividend after 54, then repeat: 546 / 55

Moving on to step 5:
546 divided by 55 is 9 with a remainder of 51.
Put 9 as the next digit of the answer. 
Result so far: 509.0
If we take 495 away from 546, we end up with 51.
Take the next digit (1) from the dividend and append it to 51, then repeat: 511 / 55

On to step 6:
55 goes into 511 9 times with a remainder of 16.
The number 9 becomes the next digit in our result. 
Result so far: 5099.0
If we take 495 away from 511, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 7:
The number 55 fits into 160 2 times, leaving a remainder of 50.
The number 2 becomes the next digit in our result. 
Result so far: 5099.2
Subtract 110 from 160 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.

Moving on to step 8:
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: 5099.29
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.

Let's proceed to step 9:
55 can be fit into 50 0 times, resulting in a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 5099.29
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.

On to step 10:
The number 55 fits into 500 9 times, leaving a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 5099.2909
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.

Let's proceed to step 11:
When dividing 50 by 55, we get 0 with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 5099.2909
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.

Let's proceed to step 12:
55 goes into 500 9 times with a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 5099.290909
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.

Going ahead to step 13:
The number 55 fits into 50 0 times, leaving a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 5099.290909
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.

Step 14:
500 divided by 55 is 9 with a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 5099.29090909
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.

In conclusion, the division gives 5099.29090909 with a balance of 5e-09.
