280865 divided by 11 
The aim is to understand the frequency of 11 in 280865.

Let's proceed to step 1:
11 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
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 / 11

On to step 2:
When dividing 28 by 11, we get 2 with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 22 from 28 leaves us with 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 11

Advancing to step 3:
11 can be fit into 60 5 times, resulting in a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 25.0
Subtract 55 from 60 to get 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 11

Step 4:
The number 11 fits into 58 5 times, leaving a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 255.0
Deduct 55 from 58 and we're left with 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 11

On to step 5:
When dividing 36 by 11, we get 3 with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 2553.0
Deduct 33 from 36 and we're left with 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 11

Let's proceed to step 6:
11 can be fit into 35 3 times, resulting in a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 25533.0
If we subtract 33 from 35, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
The number 11 fits into 20 1 times, leaving a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 25533.1
Subtract 11 from 20 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 8:
11 goes into 90 8 times with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 25533.18
Subtracting 88 from 90 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 9:
20 divided by 11 is 1 with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 25533.181
Subtracting 11 from 20 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 10:
If we divide 90 by 11, we get 8 and a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 25533.1818
If we take 88 away from 90, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 11:
20 divided by 11 is 1 with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 25533.18181
Deduct 11 from 20 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 12:
11 goes into 90 8 times with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 25533.181818
If we take 88 away from 90, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 13:
11 can be fit into 20 1 times, resulting in a remainder of 9.
The next digit of our result is 1. 
Result so far: 25533.1818181
Subtracting 11 from 20 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 14:
11 goes into 90 8 times with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 25533.18181818
If we take 88 away from 90, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Our division results in 25533.18181818 with a remaining 2e-09.
