We're dividing 123985 by 11 
The aim is to understand the frequency of 11 in 123985.

Let's proceed to step 1:
If we divide 1 by 11, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 11

Step 2:
11 can be fit into 12 1 times, resulting in a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 11 from 12, we get 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 11

Let's proceed to step 3:
When dividing 13 by 11, we get 1 with a remainder of 2.
The next digit of our result is 1. 
Result so far: 11.0
Deduct 11 from 13 and we're left with 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 11

Let's proceed to step 4:
The number 11 fits into 29 2 times, leaving a remainder of 7.
The next digit of our result is 2. 
Result so far: 112.0
The remainder is 7 after subtracting 22 from 29.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 11

On to step 5:
The number 11 fits into 78 7 times, leaving a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 1127.0
Subtracting 77 from 78 leaves us with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 11

Advancing to step 6:
The number 11 fits into 15 1 times, leaving a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 11271.0
Subtract 11 from 15 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 7:
When dividing 40 by 11, we get 3 with a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 11271.3
Deduct 33 from 40 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 8:
The number 11 fits into 70 6 times, leaving a remainder of 4.
The next digit of our result is 6. 
Result so far: 11271.36
Subtract 66 from 70 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
If we divide 40 by 11, we get 3 and a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 11271.363
Deduct 33 from 40 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 10:
If we divide 70 by 11, we get 6 and a remainder of 4.
The next digit of our result is 6. 
Result so far: 11271.3636
If we take 66 away from 70, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 11:
The number 11 fits into 40 3 times, leaving a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 11271.36363
Subtract 33 from 40 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 12:
The number 11 fits into 70 6 times, leaving a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 11271.363636
Deduct 66 from 70 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 13:
The number 11 fits into 40 3 times, leaving a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 11271.3636363
The remainder is 7 after subtracting 33 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 14:
When dividing 70 by 11, we get 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 11271.36363636
Subtract 66 from 70 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

In conclusion, the division gives 11271.36363636 with a balance of 4e-09.
