575654 ÷ 66 
The aim is to understand the frequency of 66 in 575654.

Step 1:
66 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 66

Moving on to step 2:
When dividing 57 by 66, we get 0 with a remainder of 57.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 57 and we're left with 57.
Take the next digit (5) from the dividend and append it to 57, then repeat: 575 / 66

Going ahead to step 3:
575 divided by 66 is 8 with a remainder of 47.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 47 after subtracting 528 from 575.
Fetch the next digit (6) from the dividend, attach it to 47 and continue: 476 / 66

Step 4:
The number 66 fits into 476 7 times, leaving a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 87.0
Subtract 462 from 476 to get 14.
Grab the next digit (5) from the dividend, add it to 14, then carry on: 145 / 66

Going ahead to step 5:
The number 66 fits into 145 2 times, leaving a remainder of 13.
Use 2 as the next digit of our solution. 
Result so far: 872.0
If we take 132 away from 145, we end up with 13.
Bring next digit (4) of the dividend behind the 13 and repeat the process: 134 / 66

On to step 6:
134 divided by 66 is 2 with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 8722.0
Subtract 132 from 134 to 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 7:
If we divide 20 by 66, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 8722.0
Subtracting 0 from 20 leaves us 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.

Advancing to step 8:
66 can be fit into 200 3 times, resulting in a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 8722.03
Subtract 198 from 200 to 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.

Step 9:
66 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 8722.03
Subtracting 0 from 20 leaves us 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.

Going ahead to step 10:
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: 8722.0303
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.

On to step 11:
If we divide 20 by 66, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 8722.0303
Subtracting 0 from 20 leaves us 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.

Let's proceed to step 12:
If we divide 200 by 66, we get 3 and a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 8722.030303
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 13:
66 goes into 20 0 times with a remainder of 20.
The next digit of our result is 0. 
Result so far: 8722.030303
Subtracting 0 from 20 leaves us 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 14:
When dividing 200 by 66, we get 3 with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 8722.03030303
Subtract 198 from 200 to 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.

Our division results in 8722.03030303 with a remaining 2e-09.
