312993 divided by 11 
The aim is to understand the frequency of 11 in 312993.

Going ahead to step 1:
The number 11 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 11

Moving on to step 2:
11 goes into 31 2 times with a remainder of 9.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 22 from 31 leaves us with 9.
Grab the next digit (2) from the dividend, add it to 9, then carry on: 92 / 11

Moving on to step 3:
If we divide 92 by 11, we get 8 and a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 28.0
Deduct 88 from 92 and we're left with 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 11

Advancing to step 4:
The number 11 fits into 49 4 times, leaving a remainder of 5.
The number 4 becomes the next digit in our result. 
Result so far: 284.0
If we subtract 44 from 49, we get 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 11

Moving on to step 5:
The number 11 fits into 59 5 times, leaving a remainder of 4.
Record the quotient 5 as the next digit in the result. 
Result so far: 2845.0
If we subtract 55 from 59, we get 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 11

Step 6:
43 divided by 11 is 3 with a remainder of 10.
The next digit of our result is 3. 
Result so far: 28453.0
Subtract 33 from 43 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.

Moving on to step 7:
11 goes into 100 9 times with a remainder of 1.
The next digit of our result is 9. 
Result so far: 28453.9
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.

Advancing to step 8:
11 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 28453.9
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 9:
The number 11 fits into 100 9 times, leaving a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 28453.909
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.

Moving on to step 10:
The number 11 fits into 10 0 times, leaving a remainder of 10.
The next digit of our result is 0. 
Result so far: 28453.909
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.

Step 11:
When dividing 100 by 11, we get 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 28453.90909
Subtracting 99 from 100 leaves us 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 12:
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: 28453.90909
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.

On to step 13:
11 can be fit into 100 9 times, resulting in a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 28453.9090909
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 14:
10 divided by 11 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 28453.9090909
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.

The quotient of the division is 28453.9090909, and the remainder is 1e-08.
