18660442 ÷ 792 
The aim is to understand the frequency of 792 in 18660442.

Step 1:
If we divide 1 by 792, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 792

On to step 2:
18 divided by 792 is 0 with a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Include the next digit (6) from the dividend after 18, then repeat: 186 / 792

Moving on to step 3:
If we divide 186 by 792, we get 0 and a remainder of 186.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 186 and we're left with 186.
Grab the next digit (6) from the dividend, add it to 186, then carry on: 1866 / 792

Moving on to step 4:
792 can be fit into 1866 2 times, resulting in a remainder of 282.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 1584 from 1866 leaves us with 282.
Take the next digit (0) from the dividend and append it to 282, then repeat: 2820 / 792

On to step 5:
The number 792 fits into 2820 3 times, leaving a remainder of 444.
Use 3 as the next digit of our solution. 
Result so far: 23.0
Subtract 2376 from 2820 to get 444.
Grab the next digit (4) from the dividend, add it to 444, then carry on: 4444 / 792

Let's proceed to step 6:
The number 792 fits into 4444 5 times, leaving a remainder of 484.
Use 5 as the next digit of our solution. 
Result so far: 235.0
Subtracting 3960 from 4444 leaves us with 484.
Include the next digit (4) from the dividend after 484, then repeat: 4844 / 792

Going ahead to step 7:
The number 792 fits into 4844 6 times, leaving a remainder of 92.
The next digit of our result is 6. 
Result so far: 2356.0
Deduct 4752 from 4844 and we're left with 92.
Include the next digit (2) from the dividend after 92, then repeat: 922 / 792

On to step 8:
792 goes into 922 1 times with a remainder of 130.
The number 1 becomes the next digit in our result. 
Result so far: 23561.0
Subtracting 792 from 922 leaves us with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

On to step 9:
If we divide 1300 by 792, we get 1 and a remainder of 508.
The next digit of our result is 1. 
Result so far: 23561.1
Subtracting 792 from 1300 leaves us with 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

Going ahead to step 10:
The number 792 fits into 5080 6 times, leaving a remainder of 328.
Record the quotient 6 as the next digit in the result. 
Result so far: 23561.16
If we take 4752 away from 5080, we end up with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Step 11:
792 can be fit into 3280 4 times, resulting in a remainder of 112.
The next digit of our result is 4. 
Result so far: 23561.164
If we subtract 3168 from 3280, we get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Going ahead to step 12:
792 goes into 1120 1 times with a remainder of 328.
The next digit of our result is 1. 
Result so far: 23561.1641
If we subtract 792 from 1120, we get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Moving on to step 13:
When dividing 3280 by 792, we get 4 with a remainder of 112.
The number 4 becomes the next digit in our result. 
Result so far: 23561.16414
If we take 3168 away from 3280, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Let's proceed to step 14:
If we divide 1120 by 792, we get 1 and a remainder of 328.
The number 1 becomes the next digit in our result. 
Result so far: 23561.164141
Subtracting 792 from 1120 leaves us with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Going ahead to step 15:
The number 792 fits into 3280 4 times, leaving a remainder of 112.
The next digit of our result is 4. 
Result so far: 23561.1641414
Subtract 3168 from 3280 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

On to step 16:
The number 792 fits into 1120 1 times, leaving a remainder of 328.
Write down 1 as next digit of the result. 
Result so far: 23561.16414141
Deduct 792 from 1120 and we're left with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

The final result is 23561.16414141 with a remainder of 3.28e-07.
