481250 ÷ 66 
The aim is to understand the frequency of 66 in 481250.

Going ahead to step 1:
If we divide 4 by 66, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 66

Let's proceed to step 2:
66 can be fit into 48 0 times, resulting in a remainder of 48.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 48 after subtracting 0 from 48.
Fetch the next digit (1) from the dividend, attach it to 48 and continue: 481 / 66

Step 3:
66 can be fit into 481 7 times, resulting in a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 462 from 481 to get 19.
Grab the next digit (2) from the dividend, add it to 19, then carry on: 192 / 66

Let's proceed to step 4:
66 can be fit into 192 2 times, resulting in a remainder of 60.
The next digit of our result is 2. 
Result so far: 72.0
Subtracting 132 from 192 leaves us with 60.
Grab the next digit (5) from the dividend, add it to 60, then carry on: 605 / 66

On to step 5:
66 goes into 605 9 times with a remainder of 11.
The next digit of our result is 9. 
Result so far: 729.0
If we take 594 away from 605, we end up with 11.
Bring next digit (0) of the dividend behind the 11 and repeat the process: 110 / 66

Let's proceed to step 6:
The number 66 fits into 110 1 times, leaving a remainder of 44.
Record the quotient 1 as the next digit in the result. 
Result so far: 7291.0
If we subtract 66 from 110, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 7:
66 goes into 440 6 times with a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 7291.6
Subtracting 396 from 440 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 8:
The number 66 fits into 440 6 times, leaving a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 7291.66
If we take 396 away from 440, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The final outcome is 7291.66, with a leftover of 0.044.
