We're dividing 392171 by 11 
The aim is to understand the frequency of 11 in 392171.

Let's proceed to step 1:
3 divided by 11 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 11

On to step 2:
The number 11 fits into 39 3 times, leaving a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 33 away from 39, we end up with 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 11

Let's proceed to step 3:
When dividing 62 by 11, we get 5 with a remainder of 7.
Put 5 as the next digit of the answer. 
Result so far: 35.0
Subtract 55 from 62 to get 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 11

Moving on to step 4:
11 can be fit into 71 6 times, resulting in a remainder of 5.
Use 6 as the next digit of our solution. 
Result so far: 356.0
If we take 66 away from 71, we end up with 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 11

Let's proceed to step 5:
The number 11 fits into 57 5 times, leaving a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 3565.0
Deduct 55 from 57 and we're left with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 11

Advancing to step 6:
When dividing 21 by 11, we get 1 with a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 35651.0
Subtract 11 from 21 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 7:
The number 11 fits into 100 9 times, leaving a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 35651.9
Subtracting 99 from 100 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 8:
If we divide 10 by 11, we get 0 and a remainder of 10.
The next digit of our result is 0. 
Result so far: 35651.9
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
When dividing 100 by 11, we get 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 35651.909
The remainder is 1 after subtracting 99 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 10:
When dividing 10 by 11, we get 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 35651.909
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 11:
If we divide 100 by 11, we get 9 and a remainder of 1.
The next digit of our result is 9. 
Result so far: 35651.90909
If we subtract 99 from 100, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 12:
11 can be fit into 10 0 times, resulting in a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 35651.90909
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 13:
If we divide 100 by 11, we get 9 and a remainder of 1.
The next digit of our result is 9. 
Result so far: 35651.9090909
If we subtract 99 from 100, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 14:
When dividing 10 by 11, we get 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 35651.9090909
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 35651.9090909, with a leftover of 1e-08.
