491888 ÷ 11 
The aim is to understand the frequency of 11 in 491888.

Advancing to step 1:
4 divided by 11 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 11

Step 2:
If we divide 49 by 11, we get 4 and a remainder of 5.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 5 after subtracting 44 from 49.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 11

Step 3:
51 divided by 11 is 4 with a remainder of 7.
Put 4 as the next digit of the answer. 
Result so far: 44.0
Subtracting 44 from 51 leaves us with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 11

Moving on to step 4:
If we divide 78 by 11, we get 7 and a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 447.0
If we subtract 77 from 78, we get 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 11

Let's proceed to step 5:
When dividing 18 by 11, we get 1 with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 4471.0
If we take 11 away from 18, we end up with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 11

On to step 6:
78 divided by 11 is 7 with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 44717.0
If we take 77 away from 78, we end up 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.

Step 7:
11 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 44717.0
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.

Let's proceed to step 8:
The number 11 fits into 100 9 times, leaving a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 44717.09
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.

Step 9:
10 divided by 11 is 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 44717.09
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:
If we divide 100 by 11, we get 9 and a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 44717.0909
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.

Step 11:
When dividing 10 by 11, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 44717.0909
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.

On to step 12:
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: 44717.090909
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.

Going ahead to step 13:
10 divided by 11 is 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 44717.090909
Subtract 0 from 10 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.

On to step 14:
When dividing 100 by 11, we get 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 44717.09090909
If we take 99 away from 100, we end up 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.

The final outcome is 44717.09090909, with a leftover of 1e-09.
