We look at the division of 462394 by 66 
The aim is to understand the frequency of 66 in 462394.

Step 1:
The number 66 fits into 4 0 times, leaving 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.
Bring next digit (6) of the dividend behind the 4 and repeat the process: 46 / 66

On to step 2:
The number 66 fits into 46 0 times, leaving a remainder of 46.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 46 leaves us with 46.
Include the next digit (2) from the dividend after 46, then repeat: 462 / 66

On to step 3:
66 goes into 462 7 times with a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
The remainder is 0 after subtracting 462 from 462.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 66

On to step 4:
When dividing 3 by 66, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 70.0
If we subtract 0 from 3, we get 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 66

Step 5:
The number 66 fits into 39 0 times, leaving a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 700.0
The remainder is 39 after subtracting 0 from 39.
Include the next digit (4) from the dividend after 39, then repeat: 394 / 66

Step 6:
66 can be fit into 394 5 times, resulting in a remainder of 64.
Record the quotient 5 as the next digit in the result. 
Result so far: 7005.0
If we subtract 330 from 394, we get 64.
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 7:
The number 66 fits into 640 9 times, leaving a remainder of 46.
The next digit of our result is 9. 
Result so far: 7005.9
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.

On to step 8:
460 divided by 66 is 6 with a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 7005.96
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.

Going ahead to step 9:
66 can be fit into 640 9 times, resulting in a remainder of 46.
Record the quotient 9 as the next digit in the result. 
Result so far: 7005.969
Subtract 594 from 640 to 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.

Going ahead to step 10:
The number 66 fits into 460 6 times, leaving a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 7005.9696
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 11:
When dividing 640 by 66, we get 9 with a remainder of 46.
Write down 9 as next digit of the result. 
Result so far: 7005.96969
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 12:
The number 66 fits into 460 6 times, leaving a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 7005.969696
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 13:
66 can be fit into 640 9 times, resulting in a remainder of 46.
Record the quotient 9 as the next digit in the result. 
Result so far: 7005.9696969
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.

Going ahead to step 14:
66 can be fit into 460 6 times, resulting in a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 7005.96969696
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.

After the division, we end up with 7005.96969696 and a remainder of 6.4e-08.
