72966153 ÷ 11 
The aim is to understand the frequency of 11 in 72966153.

Going ahead to step 1:
11 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 11

Let's proceed to step 2:
11 can be fit into 72 6 times, resulting in a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtracting 66 from 72 leaves us with 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 11

On to step 3:
11 goes into 69 6 times with a remainder of 3.
Use 6 as the next digit of our solution. 
Result so far: 66.0
Subtract 66 from 69 to get 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 11

Moving on to step 4:
11 can be fit into 36 3 times, resulting in a remainder of 3.
The next digit of our result is 3. 
Result so far: 663.0
Subtract 33 from 36 to get 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 11

Step 5:
The number 11 fits into 36 3 times, leaving a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 6633.0
If we subtract 33 from 36, we get 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 11

Moving on to step 6:
If we divide 31 by 11, we get 2 and a remainder of 9.
The next digit of our result is 2. 
Result so far: 66332.0
Deduct 22 from 31 and we're left with 9.
Grab the next digit (5) from the dividend, add it to 9, then carry on: 95 / 11

Let's proceed to step 7:
If we divide 95 by 11, we get 8 and a remainder of 7.
Put 8 as the next digit of the answer. 
Result so far: 663328.0
Subtracting 88 from 95 leaves us with 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 11

Advancing to step 8:
The number 11 fits into 73 6 times, leaving a remainder of 7.
The next digit of our result is 6. 
Result so far: 6633286.0
Subtract 66 from 73 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 9:
11 can be fit into 70 6 times, resulting in a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 6633286.6
If we take 66 away from 70, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 10:
If we divide 40 by 11, we get 3 and a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 6633286.63
Subtracting 33 from 40 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 11:
70 divided by 11 is 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 6633286.636
Deduct 66 from 70 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 12:
The number 11 fits into 40 3 times, leaving a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 6633286.6363
Deduct 33 from 40 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 13:
If we divide 70 by 11, we get 6 and a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 6633286.63636
Subtract 66 from 70 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 14:
When dividing 40 by 11, we get 3 with a remainder of 7.
The next digit of our result is 3. 
Result so far: 6633286.636363
Subtracting 33 from 40 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 15:
When dividing 70 by 11, we get 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 6633286.6363636
If we take 66 away from 70, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 16:
The number 11 fits into 40 3 times, leaving a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 6633286.63636363
If we take 33 away from 40, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The final outcome is 6633286.63636363, with a leftover of 7e-09.
