216639 divided by 11 
The aim is to understand the frequency of 11 in 216639.

Let's proceed to step 1:
11 goes into 2 0 times with 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.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 11

On to step 2:
21 divided by 11 is 1 with a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 10 after subtracting 11 from 21.
Fetch the next digit (6) from the dividend, attach it to 10 and continue: 106 / 11

Moving on to step 3:
If we divide 106 by 11, we get 9 and a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 19.0
If we take 99 away from 106, we end up with 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 11

Going ahead to step 4:
If we divide 76 by 11, we get 6 and a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 196.0
Subtract 66 from 76 to get 10.
Append the next digit (3) from the dividend to 10 and continue with: 103 / 11

Going ahead to step 5:
If we divide 103 by 11, we get 9 and a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 1969.0
If we subtract 99 from 103, we get 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 11

Let's proceed to step 6:
The number 11 fits into 49 4 times, leaving a remainder of 5.
Write down 4 as next digit of the result. 
Result so far: 19694.0
If we take 44 away from 49, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
The number 11 fits into 50 4 times, leaving a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 19694.4
Subtract 44 from 50 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 8:
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: 19694.45
Subtract 55 from 60 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 9:
If we divide 50 by 11, we get 4 and a remainder of 6.
The next digit of our result is 4. 
Result so far: 19694.454
If we subtract 44 from 50, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 10:
60 divided by 11 is 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 19694.4545
The remainder is 5 after subtracting 55 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 11:
11 goes into 50 4 times with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 19694.45454
Subtracting 44 from 50 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 12:
If we divide 60 by 11, we get 5 and a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 19694.454545
Subtract 55 from 60 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 13:
When dividing 50 by 11, we get 4 with a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 19694.4545454
The remainder is 6 after subtracting 44 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 14:
11 can be fit into 60 5 times, resulting in a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 19694.45454545
Deduct 55 from 60 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The quotient of the division is 19694.45454545, and the remainder is 5e-09.
