740321 ÷ 66 
The aim is to understand the frequency of 66 in 740321.

Moving on to step 1:
66 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 66

Going ahead to step 2:
66 goes into 74 1 times with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 66 from 74 and we're left with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 66

Going ahead to step 3:
80 divided by 66 is 1 with a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtract 66 from 80 to get 14.
Include the next digit (3) from the dividend after 14, then repeat: 143 / 66

Step 4:
The number 66 fits into 143 2 times, leaving a remainder of 11.
The number 2 becomes the next digit in our result. 
Result so far: 112.0
Subtracting 132 from 143 leaves us with 11.
Take the next digit (2) from the dividend and append it to 11, then repeat: 112 / 66

Step 5:
When dividing 112 by 66, we get 1 with a remainder of 46.
The number 1 becomes the next digit in our result. 
Result so far: 1121.0
Subtracting 66 from 112 leaves us with 46.
Append the next digit (1) from the dividend to 46 and continue with: 461 / 66

Step 6:
461 divided by 66 is 6 with a remainder of 65.
Use 6 as the next digit of our solution. 
Result so far: 11216.0
If we take 396 away from 461, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 7:
If we divide 650 by 66, we get 9 and a remainder of 56.
Write down 9 as next digit of the result. 
Result so far: 11216.9
Subtract 594 from 650 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 8:
66 can be fit into 560 8 times, resulting in a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 11216.98
If we take 528 away from 560, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 9:
66 goes into 320 4 times with a remainder of 56.
Record the quotient 4 as the next digit in the result. 
Result so far: 11216.984
Deduct 264 from 320 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 10:
When dividing 560 by 66, we get 8 with a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 11216.9848
If we take 528 away from 560, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 11:
320 divided by 66 is 4 with a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 11216.98484
If we subtract 264 from 320, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 12:
The number 66 fits into 560 8 times, leaving a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 11216.984848
Subtract 528 from 560 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 13:
If we divide 320 by 66, we get 4 and a remainder of 56.
Put 4 as the next digit of the answer. 
Result so far: 11216.9848484
Subtract 264 from 320 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 14:
560 divided by 66 is 8 with a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 11216.98484848
Deduct 528 from 560 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

In conclusion, the division gives 11216.98484848 with a balance of 3.2e-08.
