761760 ÷ 66 
The aim is to understand the frequency of 66 in 761760.

Let's proceed to step 1:
66 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 66

On to step 2:
The number 66 fits into 76 1 times, leaving a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 66 from 76 and we're left with 10.
Bring next digit (1) of the dividend behind the 10 and repeat the process: 101 / 66

Let's proceed to step 3:
When dividing 101 by 66, we get 1 with a remainder of 35.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Deduct 66 from 101 and we're left with 35.
Fetch the next digit (7) from the dividend, attach it to 35 and continue: 357 / 66

Step 4:
66 can be fit into 357 5 times, resulting in a remainder of 27.
The number 5 becomes the next digit in our result. 
Result so far: 115.0
The remainder is 27 after subtracting 330 from 357.
Take the next digit (6) from the dividend and append it to 27, then repeat: 276 / 66

Going ahead to step 5:
When dividing 276 by 66, we get 4 with a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 1154.0
If we subtract 264 from 276, we get 12.
Grab the next digit (0) from the dividend, add it to 12, then carry on: 120 / 66

Going ahead to step 6:
66 can be fit into 120 1 times, resulting in a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 11541.0
Deduct 66 from 120 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 7:
540 divided by 66 is 8 with a remainder of 12.
The next digit of our result is 8. 
Result so far: 11541.8
If we take 528 away from 540, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 8:
The number 66 fits into 120 1 times, leaving a remainder of 54.
Write down 1 as next digit of the result. 
Result so far: 11541.81
Deduct 66 from 120 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 9:
66 goes into 540 8 times with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 11541.818
If we subtract 528 from 540, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 10:
66 goes into 120 1 times with a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 11541.8181
Subtracting 66 from 120 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 11:
If we divide 540 by 66, we get 8 and a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 11541.81818
The remainder is 12 after subtracting 528 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 12:
If we divide 120 by 66, we get 1 and a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 11541.818181
Subtract 66 from 120 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 13:
66 can be fit into 540 8 times, resulting in a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 11541.8181818
If we subtract 528 from 540, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 14:
If we divide 120 by 66, we get 1 and a remainder of 54.
Record the quotient 1 as the next digit in the result. 
Result so far: 11541.81818181
If we take 66 away from 120, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

After the division, we end up with 11541.81818181 and a remainder of 5.4e-08.
