We're dividing 71520922 by 11 
The aim is to understand the frequency of 11 in 71520922.

Let's proceed to step 1:
11 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 11

Going ahead to step 2:
11 goes into 71 6 times with a remainder of 5.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 66 from 71 and we're left with 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 11

Going ahead to step 3:
55 divided by 11 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 65.0
If we subtract 55 from 55, we get 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 11

Going ahead to step 4:
The number 11 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 650.0
If we take 0 away from 2, we end up with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 11

Let's proceed to step 5:
When dividing 20 by 11, we get 1 with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 6501.0
The remainder is 9 after subtracting 11 from 20.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 11

Moving on to step 6:
If we divide 99 by 11, we get 9 and a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 65019.0
The remainder is 0 after subtracting 99 from 99.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 11

On to step 7:
2 divided by 11 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 650190.0
Subtract 0 from 2 to get 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 11

Moving on to step 8:
If we divide 22 by 11, we get 2 and a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 6501902.0
The remainder is 0 after subtracting 22 from 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
The number 11 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 6501902.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
When dividing 0 by 11, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 6501902.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 6501902.0 and a remainder of 0.0.
