We look at the division of 181179 by 66 
The aim is to understand the frequency of 66 in 181179.

On to step 1:
The number 66 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 66

On to step 2:
The number 66 fits into 18 0 times, leaving a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Grab the next digit (1) from the dividend, add it to 18, then carry on: 181 / 66

Let's proceed to step 3:
66 goes into 181 2 times with a remainder of 49.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 132 away from 181, we end up with 49.
Bring next digit (1) of the dividend behind the 49 and repeat the process: 491 / 66

Going ahead to step 4:
The number 66 fits into 491 7 times, leaving a remainder of 29.
Use 7 as the next digit of our solution. 
Result so far: 27.0
Deduct 462 from 491 and we're left with 29.
Fetch the next digit (7) from the dividend, attach it to 29 and continue: 297 / 66

Let's proceed to step 5:
When dividing 297 by 66, we get 4 with a remainder of 33.
The number 4 becomes the next digit in our result. 
Result so far: 274.0
Subtract 264 from 297 to get 33.
Append the next digit (9) from the dividend to 33 and continue with: 339 / 66

Let's proceed to step 6:
When dividing 339 by 66, we get 5 with a remainder of 9.
Put 5 as the next digit of the answer. 
Result so far: 2745.0
If we subtract 330 from 339, 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.

Advancing to step 7:
The number 66 fits into 90 1 times, leaving a remainder of 24.
Put 1 as the next digit of the answer. 
Result so far: 2745.1
Subtracting 66 from 90 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 8:
240 divided by 66 is 3 with a remainder of 42.
The number 3 becomes the next digit in our result. 
Result so far: 2745.13
If we subtract 198 from 240, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 9:
If we divide 420 by 66, we get 6 and a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 2745.136
Subtracting 396 from 420 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 10:
When dividing 240 by 66, we get 3 with a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 2745.1363
If we take 198 away from 240, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 11:
420 divided by 66 is 6 with a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 2745.13636
If we take 396 away from 420, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 12:
If we divide 240 by 66, we get 3 and a remainder of 42.
The number 3 becomes the next digit in our result. 
Result so far: 2745.136363
Subtracting 198 from 240 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 13:
When dividing 420 by 66, we get 6 with a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 2745.1363636
Subtract 396 from 420 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 14:
240 divided by 66 is 3 with a remainder of 42.
Record the quotient 3 as the next digit in the result. 
Result so far: 2745.13636363
If we take 198 away from 240, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The quotient of the division is 2745.13636363, and the remainder is 4.2e-08.
