266755 divided by 66 
The aim is to understand the frequency of 66 in 266755.

Step 1:
66 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 66

Moving on to step 2:
The number 66 fits into 26 0 times, leaving a remainder of 26.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 26 after subtracting 0 from 26.
Include the next digit (6) from the dividend after 26, then repeat: 266 / 66

Advancing to step 3:
When dividing 266 by 66, we get 4 with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 264 from 266 to get 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 66

Advancing to step 4:
The number 66 fits into 27 0 times, leaving a remainder of 27.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
Deduct 0 from 27 and we're left with 27.
Bring next digit (5) of the dividend behind the 27 and repeat the process: 275 / 66

Moving on to step 5:
66 goes into 275 4 times with a remainder of 11.
Record the quotient 4 as the next digit in the result. 
Result so far: 404.0
If we subtract 264 from 275, we get 11.
Grab the next digit (5) from the dividend, add it to 11, then carry on: 115 / 66

Advancing to step 6:
The number 66 fits into 115 1 times, leaving a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 4041.0
If we subtract 66 from 115, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 7:
66 goes into 490 7 times with a remainder of 28.
Record the quotient 7 as the next digit in the result. 
Result so far: 4041.7
Subtract 462 from 490 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 8:
66 can be fit into 280 4 times, resulting in a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 4041.74
Subtract 264 from 280 to 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.

Moving on to step 9:
66 goes into 160 2 times with a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 4041.742
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:
The number 66 fits into 280 4 times, leaving a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 4041.7424
Subtract 264 from 280 to 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:
The number 66 fits into 160 2 times, leaving a remainder of 28.
The next digit of our result is 2. 
Result so far: 4041.74242
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.

Let's proceed to step 12:
If we divide 280 by 66, we get 4 and a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 4041.742424
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 13:
66 goes into 160 2 times with a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 4041.7424242
If we subtract 132 from 160, we get 28.
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:
If we divide 280 by 66, we get 4 and a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 4041.74242424
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 4041.74242424, and the remainder is 1.6e-08.
