Let's divide 487816 by 11
The aim is to understand the frequency of 11 in 487816.

On to step 1:
If we divide 4 by 11, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 11

On to step 2:
When dividing 48 by 11, we get 4 with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 44 from 48, we get 4.
Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 11

Advancing to step 3:
11 can be fit into 47 4 times, resulting in a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 44.0
Deduct 44 from 47 and we're left with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 11

Advancing to step 4:
If we divide 38 by 11, we get 3 and a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 443.0
Subtract 33 from 38 to get 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 11

Moving on to step 5:
The number 11 fits into 51 4 times, leaving a remainder of 7.
The number 4 becomes the next digit in our result. 
Result so far: 4434.0
Subtracting 44 from 51 leaves us with 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 11

Going ahead to step 6:
If we divide 76 by 11, we get 6 and a remainder of 10.
The next digit of our result is 6. 
Result so far: 44346.0
If we subtract 66 from 76, 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.

Advancing to step 7:
11 can be fit into 100 9 times, resulting in a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 44346.9
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.

Moving on to step 8:
If we divide 10 by 11, we get 0 and a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 44346.9
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.

Going ahead to step 9:
100 divided by 11 is 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 44346.909
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 10:
11 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 44346.909
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.

On to step 11:
100 divided by 11 is 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 44346.90909
Subtract 99 from 100 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.

Advancing to step 12:
11 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 44346.90909
Deduct 0 from 10 and we're left 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 13:
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: 44346.9090909
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.

Going ahead to step 14:
If we divide 10 by 11, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 44346.9090909
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.

The quotient of the division is 44346.9090909, and the remainder is 1e-08.
