672454 ÷ 66 
The aim is to understand the frequency of 66 in 672454.

Going ahead to step 1:
66 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 66

Moving on to step 2:
When dividing 67 by 66, we get 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 66 from 67 to get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 66

Going ahead to step 3:
When dividing 12 by 66, we get 0 with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Deduct 0 from 12 and we're left with 12.
Take the next digit (4) from the dividend and append it to 12, then repeat: 124 / 66

Let's proceed to step 4:
When dividing 124 by 66, we get 1 with a remainder of 58.
Use 1 as the next digit of our solution. 
Result so far: 101.0
Subtract 66 from 124 to get 58.
Fetch the next digit (5) from the dividend, attach it to 58 and continue: 585 / 66

Let's proceed to step 5:
If we divide 585 by 66, we get 8 and a remainder of 57.
Write down 8 as next digit of the result. 
Result so far: 1018.0
If we take 528 away from 585, we end up with 57.
Take the next digit (4) from the dividend and append it to 57, then repeat: 574 / 66

Let's proceed to step 6:
66 can be fit into 574 8 times, resulting in a remainder of 46.
Record the quotient 8 as the next digit in the result. 
Result so far: 10188.0
Subtracting 528 from 574 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 7:
If we divide 460 by 66, we get 6 and a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 10188.6
The remainder is 64 after subtracting 396 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 8:
640 divided by 66 is 9 with a remainder of 46.
Put 9 as the next digit of the answer. 
Result so far: 10188.69
Subtracting 594 from 640 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 9:
66 goes into 460 6 times with a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 10188.696
Deduct 396 from 460 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 10:
If we divide 640 by 66, we get 9 and a remainder of 46.
Put 9 as the next digit of the answer. 
Result so far: 10188.6969
The remainder is 46 after subtracting 594 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 11:
When dividing 460 by 66, we get 6 with a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 10188.69696
Deduct 396 from 460 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 12:
66 can be fit into 640 9 times, resulting in a remainder of 46.
Put 9 as the next digit of the answer. 
Result so far: 10188.696969
If we subtract 594 from 640, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 13:
66 can be fit into 460 6 times, resulting in a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 10188.6969696
Subtracting 396 from 460 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 14:
The number 66 fits into 640 9 times, leaving a remainder of 46.
Put 9 as the next digit of the answer. 
Result so far: 10188.69696969
Deduct 594 from 640 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

In conclusion, the division gives 10188.69696969 with a balance of 4.6e-08.
