8478 ÷ 11 
The aim is to understand the frequency of 11 in 8478.

Let's proceed to step 1:
The number 11 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 11

Step 2:
The number 11 fits into 84 7 times, leaving a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 77 away from 84, we end up with 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 11

Advancing to step 3:
If we divide 77 by 11, we get 7 and a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 77.0
Subtract 77 from 77 to get 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 11

Advancing to step 4:
11 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 770.0
If we subtract 0 from 8, we 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.

On to step 5:
11 can be fit into 80 7 times, resulting in a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 770.7
Subtracting 77 from 80 leaves us 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 6:
If we divide 30 by 11, we get 2 and a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 770.72
Deduct 22 from 30 and we're left 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.

On to step 7:
The number 11 fits into 80 7 times, leaving a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 770.727
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.

Going ahead to step 8:
30 divided by 11 is 2 with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 770.7272
The remainder is 8 after subtracting 22 from 30.
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 9:
The number 11 fits into 80 7 times, leaving a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 770.72727
Subtract 77 from 80 to get 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 10:
11 can be fit into 30 2 times, resulting in a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 770.727272
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.

Moving on to step 11:
The number 11 fits into 80 7 times, leaving a remainder of 3.
The next digit of our result is 7. 
Result so far: 770.7272727
Subtracting 77 from 80 leaves us 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 12:
When dividing 30 by 11, we get 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 770.72727272
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.

Our division results in 770.72727272 with a remaining 8e-09.
