873049 divided by 11 
The aim is to understand the frequency of 11 in 873049.

Let's proceed to step 1:
When dividing 8 by 11, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 11

On to step 2:
The number 11 fits into 87 7 times, leaving a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 77 from 87 and we're left with 10.
Take the next digit (3) from the dividend and append it to 10, then repeat: 103 / 11

Advancing to step 3:
If we divide 103 by 11, we get 9 and a remainder of 4.
The next digit of our result is 9. 
Result so far: 79.0
If we take 99 away from 103, we end up with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 11

Going ahead to step 4:
11 goes into 40 3 times with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 793.0
Subtract 33 from 40 to get 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 11

On to step 5:
11 can be fit into 74 6 times, resulting in a remainder of 8.
The next digit of our result is 6. 
Result so far: 7936.0
Subtract 66 from 74 to get 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 11

On to step 6:
89 divided by 11 is 8 with a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 79368.0
Subtract 88 from 89 to 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.

Let's proceed to step 7:
When dividing 10 by 11, we get 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 79368.0
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.

Moving on to step 8:
11 goes into 100 9 times with a remainder of 1.
The next digit of our result is 9. 
Result so far: 79368.09
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.

Advancing to step 9:
10 divided by 11 is 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 79368.09
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.

Moving on to step 10:
100 divided by 11 is 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 79368.0909
Deduct 99 from 100 and we're left 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 11:
If we divide 10 by 11, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 79368.0909
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.

Advancing to step 12:
When dividing 100 by 11, we get 9 with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 79368.090909
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.

Going ahead to step 13:
11 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 79368.090909
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.

Going ahead to step 14:
100 divided by 11 is 9 with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 79368.09090909
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.

The quotient of the division is 79368.09090909, and the remainder is 1e-09.
