We look at the division of 280981 by 11 
The aim is to understand the frequency of 11 in 280981.

On to step 1:
2 divided by 11 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 11

Going ahead to step 2:
The number 11 fits into 28 2 times, leaving a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 6 after subtracting 22 from 28.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 11

Step 3:
60 divided by 11 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
The remainder is 5 after subtracting 55 from 60.
Grab the next digit (9) from the dividend, add it to 5, then carry on: 59 / 11

Let's proceed to step 4:
When dividing 59 by 11, we get 5 with a remainder of 4.
The next digit of our result is 5. 
Result so far: 255.0
Subtract 55 from 59 to get 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 11

Step 5:
The number 11 fits into 48 4 times, leaving a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 2554.0
The remainder is 4 after subtracting 44 from 48.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 11

Moving on to step 6:
The number 11 fits into 41 3 times, leaving a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 25543.0
Deduct 33 from 41 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 7:
80 divided by 11 is 7 with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 25543.7
If we take 77 away from 80, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 8:
11 can be fit into 30 2 times, resulting in a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 25543.72
If we subtract 22 from 30, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
The number 11 fits into 80 7 times, leaving a remainder of 3.
The next digit of our result is 7. 
Result so far: 25543.727
If we subtract 77 from 80, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 10:
If we divide 30 by 11, we get 2 and a remainder of 8.
The next digit of our result is 2. 
Result so far: 25543.7272
Subtracting 22 from 30 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 11:
11 goes into 80 7 times with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 25543.72727
If we take 77 away from 80, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 12:
11 goes into 30 2 times with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 25543.727272
The remainder is 8 after subtracting 22 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 13:
When dividing 80 by 11, we get 7 with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 25543.7272727
The remainder is 3 after subtracting 77 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 14:
If we divide 30 by 11, we get 2 and a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 25543.72727272
Subtracting 22 from 30 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

In conclusion, the division gives 25543.72727272 with a balance of 8e-09.
