We look at the division of 195374 by 66 
The aim is to understand the frequency of 66 in 195374.

Going ahead to step 1:
66 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 66

Step 2:
66 can be fit into 19 0 times, resulting in a remainder of 19.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 19, we get 19.
Take the next digit (5) from the dividend and append it to 19, then repeat: 195 / 66

On to step 3:
195 divided by 66 is 2 with a remainder of 63.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 132 from 195, we get 63.
Take the next digit (3) from the dividend and append it to 63, then repeat: 633 / 66

Going ahead to step 4:
633 divided by 66 is 9 with a remainder of 39.
Write down 9 as next digit of the result. 
Result so far: 29.0
If we subtract 594 from 633, we get 39.
Append the next digit (7) from the dividend to 39 and continue with: 397 / 66

Step 5:
The number 66 fits into 397 6 times, leaving a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 296.0
If we take 396 away from 397, we end up with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 66

Let's proceed to step 6:
The number 66 fits into 14 0 times, leaving a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 2960.0
The remainder is 14 after subtracting 0 from 14.
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 7:
66 can be fit into 140 2 times, resulting in a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 2960.2
The remainder is 8 after subtracting 132 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 8:
If we divide 80 by 66, we get 1 and a remainder of 14.
The next digit of our result is 1. 
Result so far: 2960.21
Subtracting 66 from 80 leaves us 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.

Moving on to step 9:
If we divide 140 by 66, we get 2 and a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 2960.212
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.

Going ahead to step 10:
80 divided by 66 is 1 with a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 2960.2121
Subtracting 66 from 80 leaves us 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.

Moving on to step 11:
140 divided by 66 is 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 2960.21212
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 12:
When dividing 80 by 66, we get 1 with a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 2960.212121
Deduct 66 from 80 and we're left 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.

Moving on to step 13:
When dividing 140 by 66, we get 2 with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 2960.2121212
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 14:
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: 2960.21212121
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.

After the division, we end up with 2960.21212121 and a remainder of 1.4e-08.
