709502 ÷ 66 
The aim is to understand the frequency of 66 in 709502.

Moving on to step 1:
66 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 66

Going ahead to step 2:
If we divide 70 by 66, we get 1 and a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 66 from 70 and we're left with 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 66

Moving on to step 3:
49 divided by 66 is 0 with a remainder of 49.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we subtract 0 from 49, we get 49.
Bring next digit (5) of the dividend behind the 49 and repeat the process: 495 / 66

Let's proceed to step 4:
66 goes into 495 7 times with a remainder of 33.
Record the quotient 7 as the next digit in the result. 
Result so far: 107.0
Subtracting 462 from 495 leaves us with 33.
Grab the next digit (0) from the dividend, add it to 33, then carry on: 330 / 66

Advancing to step 5:
The number 66 fits into 330 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 1075.0
Subtracting 330 from 330 leaves us with 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 66

Going ahead to step 6:
The number 66 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 10750.0
If we subtract 0 from 2, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
20 divided by 66 is 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 10750.0
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
The number 66 fits into 200 3 times, leaving a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 10750.03
Deduct 198 from 200 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 9:
66 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 10750.03
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 10:
66 can be fit into 200 3 times, resulting in a remainder of 2.
The next digit of our result is 3. 
Result so far: 10750.0303
The remainder is 2 after subtracting 198 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 11:
If we divide 20 by 66, we get 0 and a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 10750.0303
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 12:
When dividing 200 by 66, we get 3 with a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 10750.030303
If we subtract 198 from 200, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 13:
20 divided by 66 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 10750.030303
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 14:
When dividing 200 by 66, we get 3 with a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 10750.03030303
Deduct 198 from 200 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Our division results in 10750.03030303 with a remaining 2e-09.
