870456 ÷ 11 
The aim is to understand the frequency of 11 in 870456.

Moving on to step 1:
If we divide 8 by 11, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 11

Going ahead to step 2:
11 goes into 87 7 times with a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
The remainder is 10 after subtracting 77 from 87.
Include the next digit (0) from the dividend after 10, then repeat: 100 / 11

Let's proceed to step 3:
When dividing 100 by 11, we get 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 79.0
If we take 99 away from 100, we end up with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 11

On to step 4:
If we divide 14 by 11, we get 1 and a remainder of 3.
The next digit of our result is 1. 
Result so far: 791.0
If we take 11 away from 14, we end up with 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 11

On to step 5:
11 goes into 35 3 times with a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 7913.0
If we subtract 33 from 35, we get 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 11

On to step 6:
The number 11 fits into 26 2 times, leaving a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 79132.0
If we take 22 away from 26, 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.

Advancing to step 7:
If we divide 40 by 11, we get 3 and a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 79132.3
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 8:
11 goes into 70 6 times with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 79132.36
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.

Moving on to step 9:
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: 79132.363
If we take 33 away from 40, we end up 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.

Going ahead to step 10:
11 can be fit into 70 6 times, resulting in a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 79132.3636
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 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: 79132.36363
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 12:
If we divide 70 by 11, we get 6 and a remainder of 4.
The next digit of our result is 6. 
Result so far: 79132.363636
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.

Going ahead to step 13:
11 goes into 40 3 times with a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 79132.3636363
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.

Advancing to step 14:
11 goes into 70 6 times with a remainder of 4.
The next digit of our result is 6. 
Result so far: 79132.36363636
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.

The final result is 79132.36363636 with a remainder of 4e-09.
