We're dividing 201793 by 66 
The aim is to understand the frequency of 66 in 201793.

Step 1:
66 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 66

Step 2:
If we divide 20 by 66, we get 0 and a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Include the next digit (1) from the dividend after 20, then repeat: 201 / 66

Advancing to step 3:
66 can be fit into 201 3 times, resulting in a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 198 from 201 and we're left with 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 66

Moving on to step 4:
66 can be fit into 37 0 times, resulting in a remainder of 37.
Use 0 as the next digit of our solution. 
Result so far: 30.0
Deduct 0 from 37 and we're left with 37.
Append the next digit (9) from the dividend to 37 and continue with: 379 / 66

Let's proceed to step 5:
When dividing 379 by 66, we get 5 with a remainder of 49.
The number 5 becomes the next digit in our result. 
Result so far: 305.0
Subtracting 330 from 379 leaves us with 49.
Fetch the next digit (3) from the dividend, attach it to 49 and continue: 493 / 66

Step 6:
If we divide 493 by 66, we get 7 and a remainder of 31.
Record the quotient 7 as the next digit in the result. 
Result so far: 3057.0
Deduct 462 from 493 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 7:
The number 66 fits into 310 4 times, leaving a remainder of 46.
Record the quotient 4 as the next digit in the result. 
Result so far: 3057.4
Subtracting 264 from 310 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 8:
66 goes into 460 6 times with a remainder of 64.
The next digit of our result is 6. 
Result so far: 3057.46
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:
640 divided by 66 is 9 with a remainder of 46.
Write down 9 as next digit of the result. 
Result so far: 3057.469
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 10:
The number 66 fits into 460 6 times, leaving a remainder of 64.
The next digit of our result is 6. 
Result so far: 3057.4696
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.

Moving on to step 11:
66 can be fit into 640 9 times, resulting in a remainder of 46.
The number 9 becomes the next digit in our result. 
Result so far: 3057.46969
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 12:
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: 3057.469696
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.

Step 13:
When dividing 640 by 66, we get 9 with a remainder of 46.
Use 9 as the next digit of our solution. 
Result so far: 3057.4696969
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.

Step 14:
If we divide 460 by 66, we get 6 and a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 3057.46969696
If we take 396 away from 460, we end up 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 3057.46969696 and a remainder of 6.4e-08.
