165775 ÷ 66 
The aim is to understand the frequency of 66 in 165775.

Step 1:
When dividing 1 by 66, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 66

Let's proceed to step 2:
The number 66 fits into 16 0 times, leaving a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 16 after subtracting 0 from 16.
Take the next digit (5) from the dividend and append it to 16, then repeat: 165 / 66

Moving on to step 3:
When dividing 165 by 66, we get 2 with a remainder of 33.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 33 after subtracting 132 from 165.
Bring next digit (7) of the dividend behind the 33 and repeat the process: 337 / 66

Going ahead to step 4:
The number 66 fits into 337 5 times, leaving a remainder of 7.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
The remainder is 7 after subtracting 330 from 337.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 66

Moving on to step 5:
66 can be fit into 77 1 times, resulting in a remainder of 11.
The next digit of our result is 1. 
Result so far: 251.0
If we subtract 66 from 77, we get 11.
Grab the next digit (5) from the dividend, add it to 11, then carry on: 115 / 66

Let's proceed to step 6:
66 can be fit into 115 1 times, resulting in a remainder of 49.
The number 1 becomes the next digit in our result. 
Result so far: 2511.0
Deduct 66 from 115 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 7:
490 divided by 66 is 7 with a remainder of 28.
Use 7 as the next digit of our solution. 
Result so far: 2511.7
If we take 462 away from 490, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 8:
66 goes into 280 4 times with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 2511.74
If we take 264 away from 280, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 9:
160 divided by 66 is 2 with a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 2511.742
If we take 132 away from 160, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 10:
280 divided by 66 is 4 with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 2511.7424
If we subtract 264 from 280, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 11:
160 divided by 66 is 2 with a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 2511.74242
Deduct 132 from 160 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 12:
280 divided by 66 is 4 with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 2511.742424
Subtracting 264 from 280 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 13:
If we divide 160 by 66, we get 2 and a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 2511.7424242
The remainder is 28 after subtracting 132 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 14:
The number 66 fits into 280 4 times, leaving a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 2511.74242424
If we subtract 264 from 280, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The quotient of the division is 2511.74242424, and the remainder is 1.6e-08.
