Let's divide 150720 by 11
The aim is to understand the frequency of 11 in 150720.

Step 1:
The number 11 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 11

Step 2:
When dividing 15 by 11, we get 1 with a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 4 after subtracting 11 from 15.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 11

On to step 3:
If we divide 40 by 11, we get 3 and a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we subtract 33 from 40, we get 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 11

Advancing to step 4:
The number 11 fits into 77 7 times, leaving a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 137.0
The remainder is 0 after subtracting 77 from 77.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 11

Moving on to step 5:
11 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 1370.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 11

Going ahead to step 6:
When dividing 20 by 11, we get 1 with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 13701.0
If we subtract 11 from 20, we 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.

On to step 7:
If we divide 90 by 11, we get 8 and a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 13701.8
The remainder is 2 after subtracting 88 from 90.
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 8:
11 goes into 20 1 times with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 13701.81
Deduct 11 from 20 and we're left 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.

Moving on to step 9:
90 divided by 11 is 8 with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 13701.818
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 10:
11 goes into 20 1 times with a remainder of 9.
The next digit of our result is 1. 
Result so far: 13701.8181
If we subtract 11 from 20, we 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.

Let's proceed to step 11:
11 can be fit into 90 8 times, resulting in a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 13701.81818
Subtracting 88 from 90 leaves us 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.

Let's proceed to step 12:
11 goes into 20 1 times with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 13701.818181
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.

On to step 13:
11 goes into 90 8 times with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 13701.8181818
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 14:
If we divide 20 by 11, we get 1 and a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 13701.81818181
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.

Our division results in 13701.81818181 with a remaining 9e-09.
