We're dividing 21793 by 11 
The aim is to understand the frequency of 11 in 21793.

Advancing to step 1:
If we divide 2 by 11, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 11

Moving on to step 2:
The number 11 fits into 21 1 times, leaving a remainder of 10.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 11 from 21 leaves us with 10.
Append the next digit (7) from the dividend to 10 and continue with: 107 / 11

Moving on to step 3:
11 goes into 107 9 times with a remainder of 8.
Write down 9 as next digit of the result. 
Result so far: 19.0
If we subtract 99 from 107, we get 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 11

Let's proceed to step 4:
11 can be fit into 89 8 times, resulting in a remainder of 1.
The next digit of our result is 8. 
Result so far: 198.0
Deduct 88 from 89 and we're left with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 11

Moving on to step 5:
The number 11 fits into 13 1 times, leaving a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1981.0
The remainder is 2 after subtracting 11 from 13.
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 6:
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: 1981.1
If we take 11 away from 20, we end up 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.

Going ahead to step 7:
When dividing 90 by 11, we get 8 with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 1981.18
Subtract 88 from 90 to 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.

On to step 8:
11 goes into 20 1 times with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 1981.181
The remainder is 9 after subtracting 11 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 9:
90 divided by 11 is 8 with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 1981.1818
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.

Step 10:
The number 11 fits into 20 1 times, leaving a remainder of 9.
The next digit of our result is 1. 
Result so far: 1981.18181
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 11:
90 divided by 11 is 8 with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 1981.181818
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.

Moving on to step 12:
11 can be fit into 20 1 times, resulting in a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 1981.1818181
If we subtract 11 from 20, we 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 13:
11 can be fit into 90 8 times, resulting in a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 1981.18181818
Subtract 88 from 90 to 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.

The final result is 1981.18181818 with a remainder of 2e-09.
