Let's divide 305802 by 11
The aim is to understand the frequency of 11 in 305802.

Moving on to step 1:
The number 11 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 11

Let's proceed to step 2:
The number 11 fits into 30 2 times, leaving a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 22 from 30 leaves us with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 11

Let's proceed to step 3:
11 goes into 85 7 times with a remainder of 8.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
If we take 77 away from 85, we end up with 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 11

Going ahead to step 4:
The number 11 fits into 88 8 times, leaving a remainder of 0.
The next digit of our result is 8. 
Result so far: 278.0
If we take 88 away from 88, we end up with 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 11

Going ahead to step 5:
11 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 2780.0
Subtract 0 from 0 to get 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 11

Step 6:
11 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 27800.0
If we take 0 away from 2, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
20 divided by 11 is 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 27800.1
Subtract 11 from 20 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 8:
The number 11 fits into 90 8 times, leaving a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 27800.18
Subtract 88 from 90 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 9:
11 can be fit into 20 1 times, resulting in a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 27800.181
The remainder is 9 after subtracting 11 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 10:
If we divide 90 by 11, we get 8 and a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 27800.1818
If we subtract 88 from 90, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 11:
11 can be fit into 20 1 times, resulting in a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 27800.18181
If we take 11 away from 20, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 12:
11 can be fit into 90 8 times, resulting in a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 27800.181818
If we subtract 88 from 90, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 13:
The number 11 fits into 20 1 times, leaving a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 27800.1818181
Subtracting 11 from 20 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 14:
90 divided by 11 is 8 with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 27800.18181818
Deduct 88 from 90 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final result is 27800.18181818 with a remainder of 2e-09.
