We look at the division of 468773 by 66 
The aim is to understand the frequency of 66 in 468773.

Step 1:
When dividing 4 by 66, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (6) from the dividend and append it to 4, then repeat: 46 / 66

Step 2:
46 divided by 66 is 0 with a remainder of 46.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 46, we get 46.
Take the next digit (8) from the dividend and append it to 46, then repeat: 468 / 66

Step 3:
66 can be fit into 468 7 times, resulting in a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we subtract 462 from 468, we get 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 66

Let's proceed to step 4:
66 can be fit into 67 1 times, resulting in a remainder of 1.
The next digit of our result is 1. 
Result so far: 71.0
The remainder is 1 after subtracting 66 from 67.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 66

Let's proceed to step 5:
66 goes into 17 0 times with a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 710.0
If we subtract 0 from 17, we get 17.
Bring next digit (3) of the dividend behind the 17 and repeat the process: 173 / 66

Advancing to step 6:
173 divided by 66 is 2 with a remainder of 41.
The next digit of our result is 2. 
Result so far: 7102.0
Deduct 132 from 173 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 7:
When dividing 410 by 66, we get 6 with a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 7102.6
If we take 396 away from 410, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 8:
If we divide 140 by 66, we get 2 and a remainder of 8.
The next digit of our result is 2. 
Result so far: 7102.62
Subtract 132 from 140 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
If we divide 80 by 66, we get 1 and a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 7102.621
The remainder is 14 after subtracting 66 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 10:
If we divide 140 by 66, we get 2 and a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 7102.6212
If we subtract 132 from 140, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 11:
66 can be fit into 80 1 times, resulting in a remainder of 14.
The next digit of our result is 1. 
Result so far: 7102.62121
If we subtract 66 from 80, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 12:
If we divide 140 by 66, we get 2 and a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 7102.621212
If we subtract 132 from 140, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 13:
80 divided by 66 is 1 with a remainder of 14.
The next digit of our result is 1. 
Result so far: 7102.6212121
If we subtract 66 from 80, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 14:
The number 66 fits into 140 2 times, leaving a remainder of 8.
The next digit of our result is 2. 
Result so far: 7102.62121212
Subtract 132 from 140 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 7102.62121212, and the remainder is 8e-09.
