We look at the division of 945171 by 11 
The aim is to understand the frequency of 11 in 945171.

On to step 1:
The number 11 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (4) from the dividend and append it to 9, then repeat: 94 / 11

Moving on to step 2:
When dividing 94 by 11, we get 8 with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 88 from 94, we get 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 11

Step 3:
11 goes into 65 5 times with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 85.0
Deduct 55 from 65 and we're left with 10.
Bring next digit (1) of the dividend behind the 10 and repeat the process: 101 / 11

Going ahead to step 4:
11 can be fit into 101 9 times, resulting in a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 859.0
Subtracting 99 from 101 leaves us with 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 11

Going ahead to step 5:
If we divide 27 by 11, we get 2 and a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 8592.0
Subtract 22 from 27 to get 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 11

Let's proceed to step 6:
If we divide 51 by 11, we get 4 and a remainder of 7.
Record the quotient 4 as the next digit in the result. 
Result so far: 85924.0
Subtracting 44 from 51 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.

Step 7:
When dividing 70 by 11, we get 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 85924.6
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.

Going ahead to step 8:
When dividing 40 by 11, we get 3 with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 85924.63
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.

Step 9:
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: 85924.636
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.

Moving on to step 10:
If we divide 40 by 11, we get 3 and a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 85924.6363
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:
11 goes into 70 6 times with a remainder of 4.
The next digit of our result is 6. 
Result so far: 85924.63636
If we subtract 66 from 70, we 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.

Step 12:
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: 85924.636363
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.

Step 13:
The number 11 fits into 70 6 times, leaving a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 85924.6363636
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.

Step 14:
When dividing 40 by 11, we get 3 with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 85924.63636363
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.

After the division, we end up with 85924.63636363 and a remainder of 7e-09.
