780819 ÷ 11 
The aim is to understand the frequency of 11 in 780819.

Going ahead to step 1:
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: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 11

Let's proceed to step 2:
The number 11 fits into 78 7 times, leaving a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
The remainder is 1 after subtracting 77 from 78.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 11

Let's proceed to step 3:
11 goes into 10 0 times with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 70.0
Deduct 0 from 10 and we're left with 10.
Grab the next digit (8) from the dividend, add it to 10, then carry on: 108 / 11

Advancing to step 4:
The number 11 fits into 108 9 times, leaving a remainder of 9.
The next digit of our result is 9. 
Result so far: 709.0
Subtract 99 from 108 to get 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 11

Let's proceed to step 5:
91 divided by 11 is 8 with a remainder of 3.
Write down 8 as next digit of the result. 
Result so far: 7098.0
Subtract 88 from 91 to get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 11

Step 6:
11 can be fit into 39 3 times, resulting in a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 70983.0
Subtract 33 from 39 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 7:
11 goes into 60 5 times with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 70983.5
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.

Let's proceed to step 8:
50 divided by 11 is 4 with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 70983.54
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.

Let's proceed to step 9:
The number 11 fits into 60 5 times, leaving a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 70983.545
Subtracting 55 from 60 leaves us 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.

On to step 10:
The number 11 fits into 50 4 times, leaving a remainder of 6.
The next digit of our result is 4. 
Result so far: 70983.5454
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.

Moving on to step 11:
60 divided by 11 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 70983.54545
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 12:
11 can be fit into 50 4 times, resulting in a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 70983.545454
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 13:
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: 70983.5454545
If we subtract 55 from 60, we 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 14:
When dividing 50 by 11, we get 4 with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 70983.54545454
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.

Our division results in 70983.54545454 with a remaining 6e-09.
