We look at the division of 195494 by 66 
The aim is to understand the frequency of 66 in 195494.

Advancing to step 1:
1 divided by 66 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 66

On to step 2:
19 divided by 66 is 0 with a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 19, we end up with 19.
Take the next digit (5) from the dividend and append it to 19, then repeat: 195 / 66

Step 3:
When dividing 195 by 66, we get 2 with a remainder of 63.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 132 from 195 to get 63.
Append the next digit (4) from the dividend to 63 and continue with: 634 / 66

Let's proceed to step 4:
66 can be fit into 634 9 times, resulting in a remainder of 40.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
Subtracting 594 from 634 leaves us with 40.
Include the next digit (9) from the dividend after 40, then repeat: 409 / 66

Going ahead to step 5:
409 divided by 66 is 6 with a remainder of 13.
Write down 6 as next digit of the result. 
Result so far: 296.0
The remainder is 13 after subtracting 396 from 409.
Grab the next digit (4) from the dividend, add it to 13, then carry on: 134 / 66

Advancing to step 6:
134 divided by 66 is 2 with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 2962.0
The remainder is 2 after subtracting 132 from 134.
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 7:
66 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 2962.0
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.

Step 8:
The number 66 fits into 200 3 times, leaving a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 2962.03
If we take 198 away from 200, we end up 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:
20 divided by 66 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 2962.03
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.

Going ahead to step 10:
When dividing 200 by 66, we get 3 with a remainder of 2.
The next digit of our result is 3. 
Result so far: 2962.0303
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 11:
66 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 2962.0303
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.

Going ahead to step 12:
66 can be fit into 200 3 times, resulting in a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 2962.030303
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.

Advancing to step 13:
66 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 2962.030303
Deduct 0 from 20 and we're left 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.
The number 3 becomes the next digit in our result. 
Result so far: 2962.03030303
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 2962.03030303 with a remaining 2e-09.
