45326 ÷ 66 
The aim is to understand the frequency of 66 in 45326.

Going ahead to step 1:
66 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 66

Let's proceed to step 2:
If we divide 45 by 66, we get 0 and a remainder of 45.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 45 after subtracting 0 from 45.
Take the next digit (3) from the dividend and append it to 45, then repeat: 453 / 66

On to step 3:
66 goes into 453 6 times with a remainder of 57.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 396 from 453 and we're left with 57.
Grab the next digit (2) from the dividend, add it to 57, then carry on: 572 / 66

Step 4:
66 can be fit into 572 8 times, resulting in a remainder of 44.
Use 8 as the next digit of our solution. 
Result so far: 68.0
The remainder is 44 after subtracting 528 from 572.
Include the next digit (6) from the dividend after 44, then repeat: 446 / 66

Advancing to step 5:
If we divide 446 by 66, we get 6 and a remainder of 50.
The number 6 becomes the next digit in our result. 
Result so far: 686.0
Subtract 396 from 446 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 6:
66 goes into 500 7 times with a remainder of 38.
The next digit of our result is 7. 
Result so far: 686.7
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.

Advancing to step 7:
If we divide 380 by 66, we get 5 and a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 686.75
The remainder is 50 after subtracting 330 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 8:
The number 66 fits into 500 7 times, leaving a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 686.757
If we take 462 away from 500, we end up 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 9:
When dividing 380 by 66, we get 5 with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 686.7575
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.

Going ahead 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: 686.75757
Subtracting 462 from 500 leaves us 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:
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: 686.757575
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.

Step 12:
66 goes into 500 7 times with a remainder of 38.
The next digit of our result is 7. 
Result so far: 686.7575757
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.

Step 13:
When dividing 380 by 66, we get 5 with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 686.75757575
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.

In conclusion, the division gives 686.75757575 with a balance of 5e-08.
