207740 divided by 66 
The aim is to understand the frequency of 66 in 207740.

Let's proceed to step 1:
The number 66 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 66

Advancing to step 2:
66 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Take the next digit (7) from the dividend and append it to 20, then repeat: 207 / 66

Step 3:
The number 66 fits into 207 3 times, leaving a remainder of 9.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 198 from 207 to get 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 66

Let's proceed to step 4:
97 divided by 66 is 1 with a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
The remainder is 31 after subtracting 66 from 97.
Take the next digit (4) from the dividend and append it to 31, then repeat: 314 / 66

Let's proceed to step 5:
When dividing 314 by 66, we get 4 with a remainder of 50.
The next digit of our result is 4. 
Result so far: 314.0
Deduct 264 from 314 and we're left with 50.
Include the next digit (0) from the dividend after 50, then repeat: 500 / 66

Advancing to step 6:
When dividing 500 by 66, we get 7 with a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 3147.0
If we take 462 away from 500, we end up with 38.

When dividing 500 by 66, we get 7 with a remainder of 38.
Put 7 as the next digit of the answer. 
Result so far: 3147.57
If we take 462 away from 500, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 9:
66 goes into 380 5 times with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 3147.575
Deduct 330 from 380 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 10:
The number 66 fits into 500 7 times, leaving a remainder of 38.
Put 7 as the next digit of the answer. 
Result so far: 3147.5757
Subtracting 462 from 500 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 11:
66 can be fit into 380 5 times, resulting in a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 3147.57575
Subtracting 330 from 380 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 12:
66 can be fit into 500 7 times, resulting in a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 3147.575757
Subtracting 462 from 500 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 13:
When dividing 380 by 66, we get 5 with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 3147.5757575
If we subtract 330 from 380, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 14:
66 goes into 500 7 times with a remainder of 38.
The number 7 becomes the next digit in our result. 
Result so far: 3147.57575757
If we subtract 462 from 500, we get 38.
