218890 ÷ 11 
The aim is to understand the frequency of 11 in 218890.

On 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
Subtract 0 from 2 to get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 11

Going ahead to step 2:
11 can be fit into 21 1 times, resulting in a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 10 after subtracting 11 from 21.
Fetch the next digit (8) from the dividend, attach it to 10 and continue: 108 / 11

Going ahead to step 3:
The number 11 fits into 108 9 times, leaving a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Subtracting 99 from 108 leaves us with 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 11

Going ahead to step 4:
When dividing 98 by 11, we get 8 with a remainder of 10.
The next digit of our result is 8. 
Result so far: 198.0
If we subtract 88 from 98, we get 10.
Append the next digit (9) from the dividend to 10 and continue with: 109 / 11

Let's proceed to step 5:
The number 11 fits into 109 9 times, leaving a remainder of 10.
The next digit of our result is 9. 
Result so far: 1989.0
If we take 99 away from 109, we end up with 10.
Include the next digit (0) from the dividend after 10, then repeat: 100 / 11

Step 6:
11 can be fit into 100 9 times, resulting in a remainder of 1.
The next digit of our result is 9. 
Result so far: 19899.0
Subtracting 99 from 100 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
11 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 19899.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
If we divide 100 by 11, we get 9 and a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 19899.09
Deduct 99 from 100 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 9:
The number 11 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 19899.09
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 10:
11 goes into 100 9 times with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 19899.0909
If we take 99 away from 100, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 11:
11 goes into 10 0 times with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 19899.0909
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 12:
When dividing 100 by 11, we get 9 with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 19899.090909
If we subtract 99 from 100, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 13:
The number 11 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 19899.090909
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 14:
If we divide 100 by 11, we get 9 and a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 19899.09090909
Deduct 99 from 100 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

After the division, we end up with 19899.09090909 and a remainder of 1e-09.
