456873 divided by 11 
The aim is to understand the frequency of 11 in 456873.

On to step 1:
When dividing 4 by 11, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 11

Going ahead to step 2:
11 goes into 45 4 times with a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 44 away from 45, we end up with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 11

Going ahead to step 3:
If we divide 16 by 11, we get 1 and a remainder of 5.
The next digit of our result is 1. 
Result so far: 41.0
Deduct 11 from 16 and we're left with 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 11

Moving on to step 4:
58 divided by 11 is 5 with a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 415.0
Subtracting 55 from 58 leaves us with 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 11

Going ahead to step 5:
37 divided by 11 is 3 with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 4153.0
If we subtract 33 from 37, we get 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 11

Moving on to step 6:
11 can be fit into 43 3 times, resulting in a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 41533.0
If we subtract 33 from 43, 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.

Step 7:
100 divided by 11 is 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 41533.9
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.

Let's proceed to step 8:
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: 41533.9
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 9:
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: 41533.909
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.

Advancing to step 10:
When dividing 10 by 11, we get 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 41533.909
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.

Step 11:
11 goes into 100 9 times with a remainder of 1.
The next digit of our result is 9. 
Result so far: 41533.90909
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.

Let's proceed to step 12:
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: 41533.90909
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.

Step 13:
The number 11 fits into 100 9 times, leaving a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 41533.9090909
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.

Moving on to step 14:
If we divide 10 by 11, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 41533.9090909
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.

Our division results in 41533.9090909 with a remaining 1e-08.
