We look at the division of 561424 by 11 
The aim is to understand the frequency of 11 in 561424.

Moving on to step 1:
11 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (6) from the dividend and append it to 5, then repeat: 56 / 11

Moving on to step 2:
11 can be fit into 56 5 times, resulting in a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 5.0
The remainder is 1 after subtracting 55 from 56.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 11

Moving on to step 3:
11 divided by 11 is 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 51.0
If we take 11 away from 11, we end up with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 11

Step 4:
The number 11 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 510.0
Subtract 0 from 4 to get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 11

Going ahead to step 5:
42 divided by 11 is 3 with a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 5103.0
If we take 33 away from 42, we end up with 9.
Take the next digit (4) from the dividend and append it to 9, then repeat: 94 / 11

On to step 6:
If we divide 94 by 11, we get 8 and a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 51038.0
Deduct 88 from 94 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
11 goes into 60 5 times with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 51038.5
If we take 55 away from 60, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 8:
If we divide 50 by 11, we get 4 and a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 51038.54
If we take 44 away from 50, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 9:
When dividing 60 by 11, we get 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 51038.545
If we take 55 away from 60, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 10:
If we divide 50 by 11, we get 4 and a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 51038.5454
Subtract 44 from 50 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 11:
If we divide 60 by 11, we get 5 and a remainder of 5.
The next digit of our result is 5. 
Result so far: 51038.54545
Deduct 55 from 60 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 12:
When dividing 50 by 11, we get 4 with a remainder of 6.
The next digit of our result is 4. 
Result so far: 51038.545454
Subtracting 44 from 50 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 13:
If we divide 60 by 11, we get 5 and a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 51038.5454545
Subtracting 55 from 60 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 14:
The number 11 fits into 50 4 times, leaving a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 51038.54545454
Subtract 44 from 50 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

After the division, we end up with 51038.54545454 and a remainder of 6e-09.
