We look at the division of 83457723 by 11 
The aim is to understand the frequency of 11 in 83457723.

Going ahead to step 1:
When dividing 8 by 11, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 11

Step 2:
11 can be fit into 83 7 times, resulting in a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 77 from 83 and we're left with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 11

On to step 3:
11 goes into 64 5 times with a remainder of 9.
The next digit of our result is 5. 
Result so far: 75.0
Deduct 55 from 64 and we're left with 9.
Bring next digit (5) of the dividend behind the 9 and repeat the process: 95 / 11

Moving on to step 4:
If we divide 95 by 11, we get 8 and a remainder of 7.
Use 8 as the next digit of our solution. 
Result so far: 758.0
The remainder is 7 after subtracting 88 from 95.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 11

Going ahead to step 5:
11 goes into 77 7 times with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 7587.0
Deduct 77 from 77 and we're left with 0.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 11

Moving on to step 6:
When dividing 7 by 11, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 75870.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 11

Moving on to step 7:
The number 11 fits into 72 6 times, leaving a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 758706.0
If we take 66 away from 72, we end up with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 11

Going ahead to step 8:
11 can be fit into 63 5 times, resulting in a remainder of 8.
Write down 5 as next digit of the result. 
Result so far: 7587065.0
If we take 55 away from 63, 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.

Let's proceed to step 9:
If we divide 80 by 11, we get 7 and a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 7587065.7
If we take 77 away from 80, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 10:
When dividing 30 by 11, we get 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 7587065.72
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.

Let's proceed to step 11:
When dividing 80 by 11, we get 7 with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 7587065.727
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 12:
The number 11 fits into 30 2 times, leaving a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 7587065.7272
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.

Going ahead to step 13:
When dividing 80 by 11, we get 7 with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 7587065.72727
Deduct 77 from 80 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 14:
When dividing 30 by 11, we get 2 with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 7587065.727272
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 15:
80 divided by 11 is 7 with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 7587065.7272727
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.

Going ahead to step 16:
11 goes into 30 2 times with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 7587065.72727272
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.

The final outcome is 7587065.72727272, with a leftover of 8e-09.
