We look at the division of 781433 by 11 
The aim is to understand the frequency of 11 in 781433.

Moving on to step 1:
If we divide 7 by 11, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 11

Advancing to step 2:
78 divided by 11 is 7 with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 77 from 78 leaves us with 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 11

On to step 3:
The number 11 fits into 11 1 times, leaving a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 71.0
The remainder is 0 after subtracting 11 from 11.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 11

Step 4:
11 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 710.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 11

Let's proceed to step 5:
11 can be fit into 43 3 times, resulting in a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 7103.0
Deduct 33 from 43 and we're left with 10.
Bring next digit (3) of the dividend behind the 10 and repeat the process: 103 / 11

Moving on to step 6:
If we divide 103 by 11, we get 9 and a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 71039.0
If we take 99 away from 103, 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.

Moving on to step 7:
When dividing 40 by 11, we get 3 with a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 71039.3
If we subtract 33 from 40, we 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.

On to step 8:
If we divide 70 by 11, we get 6 and a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 71039.36
Subtracting 66 from 70 leaves us 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.

Let's proceed to step 9:
If we divide 40 by 11, we get 3 and a remainder of 7.
The next digit of our result is 3. 
Result so far: 71039.363
The remainder is 7 after subtracting 33 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 10:
11 can be fit into 70 6 times, resulting in a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 71039.3636
The remainder is 4 after subtracting 66 from 70.
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 11:
40 divided by 11 is 3 with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 71039.36363
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.

Step 12:
70 divided by 11 is 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 71039.363636
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.

Let's proceed to step 13:
The number 11 fits into 40 3 times, leaving a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 71039.3636363
The remainder is 7 after subtracting 33 from 40.
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 14:
70 divided by 11 is 6 with a remainder of 4.
The next digit of our result is 6. 
Result so far: 71039.36363636
The remainder is 4 after subtracting 66 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 71039.36363636 with a remainder of 4e-09.
