Let's divide 741255 by 66
The aim is to understand the frequency of 66 in 741255.

Step 1:
If we divide 7 by 66, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 66

Advancing to step 2:
66 goes into 74 1 times with a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 66 away from 74, we end up with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 66

Advancing to step 3:
66 can be fit into 81 1 times, resulting in a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtract 66 from 81 to get 15.
Fetch the next digit (2) from the dividend, attach it to 15 and continue: 152 / 66

Advancing to step 4:
66 goes into 152 2 times with a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 112.0
If we subtract 132 from 152, we get 20.
Append the next digit (5) from the dividend to 20 and continue with: 205 / 66

Step 5:
The number 66 fits into 205 3 times, leaving a remainder of 7.
The next digit of our result is 3. 
Result so far: 1123.0
Subtracting 198 from 205 leaves us with 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 66

Going ahead to step 6:
66 goes into 75 1 times with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 11231.0
The remainder is 9 after subtracting 66 from 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 7:
The number 66 fits into 90 1 times, leaving a remainder of 24.
The next digit of our result is 1. 
Result so far: 11231.1
Subtracting 66 from 90 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 8:
The number 66 fits into 240 3 times, leaving a remainder of 42.
Write down 3 as next digit of the result. 
Result so far: 11231.13
The remainder is 42 after subtracting 198 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 9:
66 goes into 420 6 times with a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 11231.136
Subtract 396 from 420 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 10:
When dividing 240 by 66, we get 3 with a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 11231.1363
Deduct 198 from 240 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 11:
When dividing 420 by 66, we get 6 with a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 11231.13636
Subtracting 396 from 420 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 12:
The number 66 fits into 240 3 times, leaving a remainder of 42.
Record the quotient 3 as the next digit in the result. 
Result so far: 11231.136363
If we subtract 198 from 240, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 13:
If we divide 420 by 66, we get 6 and a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 11231.1363636
The remainder is 24 after subtracting 396 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 14:
66 goes into 240 3 times with a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 11231.13636363
Subtracting 198 from 240 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final result is 11231.13636363 with a remainder of 4.2e-08.
