We divide 231998 by 11
The aim is to understand the frequency of 11 in 231998.

Moving on to step 1:
The number 11 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 11

Step 2:
11 goes into 23 2 times with a remainder of 1.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 22 from 23, we get 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 11

Let's proceed to step 3:
If we divide 11 by 11, we get 1 and a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
The remainder is 0 after subtracting 11 from 11.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 11

Step 4:
11 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 210.0
The remainder is 9 after subtracting 0 from 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 11

Moving on to step 5:
When dividing 99 by 11, we get 9 with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 2109.0
The remainder is 0 after subtracting 99 from 99.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 11

Advancing to step 6:
11 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 21090.0
Deduct 0 from 8 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.

On to step 7:
11 goes into 80 7 times with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 21090.7
Subtract 77 from 80 to 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.

Advancing to step 8:
When dividing 30 by 11, we get 2 with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 21090.72
Subtract 22 from 30 to 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.

Moving on to step 9:
If we divide 80 by 11, we get 7 and a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 21090.727
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:
11 can be fit into 30 2 times, resulting in a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 21090.7272
If we take 22 away from 30, we end up 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.

Moving on to step 11:
11 can be fit into 80 7 times, resulting in a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 21090.72727
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.

On to step 12:
The number 11 fits into 30 2 times, leaving a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 21090.727272
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.

Advancing 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: 21090.7272727
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.

Advancing to step 14:
The number 11 fits into 30 2 times, leaving a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 21090.72727272
Subtract 22 from 30 to 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.

The quotient of the division is 21090.72727272, and the remainder is 8e-09.
