We're dividing 199754 by 66 
The aim is to understand the frequency of 66 in 199754.

Moving on to step 1:
If we divide 1 by 66, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 66

Let's proceed to step 2:
66 can be fit into 19 0 times, resulting in a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 19 and we're left with 19.
Grab the next digit (9) from the dividend, add it to 19, then carry on: 199 / 66

Let's proceed to step 3:
If we divide 199 by 66, we get 3 and a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 1 after subtracting 198 from 199.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 66

Step 4:
When dividing 17 by 66, we get 0 with a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 30.0
Deduct 0 from 17 and we're left with 17.
Take the next digit (5) from the dividend and append it to 17, then repeat: 175 / 66

Advancing to step 5:
175 divided by 66 is 2 with a remainder of 43.
Use 2 as the next digit of our solution. 
Result so far: 302.0
Subtracting 132 from 175 leaves us with 43.
Fetch the next digit (4) from the dividend, attach it to 43 and continue: 434 / 66

Step 6:
66 goes into 434 6 times with a remainder of 38.
Record the quotient 6 as the next digit in the result. 
Result so far: 3026.0
The remainder is 38 after subtracting 396 from 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 7:
When dividing 380 by 66, we get 5 with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 3026.5
If we subtract 330 from 380, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 8:
When dividing 500 by 66, we get 7 with a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 3026.57
If we subtract 462 from 500, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 9:
When dividing 380 by 66, we get 5 with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 3026.575
Subtract 330 from 380 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 10:
66 can be fit into 500 7 times, resulting in a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 3026.5757
Deduct 462 from 500 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 11:
380 divided by 66 is 5 with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 3026.57575
Deduct 330 from 380 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 12:
66 goes into 500 7 times with a remainder of 38.
The number 7 becomes the next digit in our result. 
Result so far: 3026.575757
Deduct 462 from 500 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 13:
The number 66 fits into 380 5 times, leaving a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 3026.5757575
Subtract 330 from 380 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 14:
If we divide 500 by 66, we get 7 and a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 3026.57575757
The remainder is 38 after subtracting 462 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The final outcome is 3026.57575757, with a leftover of 3.8e-08.
