99539939 ÷ 792 
The aim is to understand the frequency of 792 in 99539939.

On to step 1:
9 divided by 792 is 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 792

Going ahead to step 2:
The number 792 fits into 99 0 times, leaving a remainder of 99.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 99, we get 99.
Take the next digit (5) from the dividend and append it to 99, then repeat: 995 / 792

Step 3:
The number 792 fits into 995 1 times, leaving a remainder of 203.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 792 from 995 leaves us with 203.
Fetch the next digit (3) from the dividend, attach it to 203 and continue: 2033 / 792

Advancing to step 4:
When dividing 2033 by 792, we get 2 with a remainder of 449.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtract 1584 from 2033 to get 449.
Bring next digit (9) of the dividend behind the 449 and repeat the process: 4499 / 792

Going ahead to step 5:
792 can be fit into 4499 5 times, resulting in a remainder of 539.
The next digit of our result is 5. 
Result so far: 125.0
Subtracting 3960 from 4499 leaves us with 539.
Grab the next digit (9) from the dividend, add it to 539, then carry on: 5399 / 792

Moving on to step 6:
792 can be fit into 5399 6 times, resulting in a remainder of 647.
The next digit of our result is 6. 
Result so far: 1256.0
If we subtract 4752 from 5399, we get 647.
Bring next digit (3) of the dividend behind the 647 and repeat the process: 6473 / 792

Step 7:
When dividing 6473 by 792, we get 8 with a remainder of 137.
Use 8 as the next digit of our solution. 
Result so far: 12568.0
Subtract 6336 from 6473 to get 137.
Bring next digit (9) of the dividend behind the 137 and repeat the process: 1379 / 792

Advancing to step 8:
792 goes into 1379 1 times with a remainder of 587.
Record the quotient 1 as the next digit in the result. 
Result so far: 125681.0
Subtract 792 from 1379 to get 587.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5870, and continue the process.

On to step 9:
The number 792 fits into 5870 7 times, leaving a remainder of 326.
Record the quotient 7 as the next digit in the result. 
Result so far: 125681.7
Deduct 5544 from 5870 and we're left with 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Let's proceed to step 10:
792 can be fit into 3260 4 times, resulting in a remainder of 92.
Record the quotient 4 as the next digit in the result. 
Result so far: 125681.74
Deduct 3168 from 3260 and we're left with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

On to step 11:
792 goes into 920 1 times with a remainder of 128.
Use 1 as the next digit of our solution. 
Result so far: 125681.741
Subtracting 792 from 920 leaves us with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Going ahead to step 12:
1280 divided by 792 is 1 with a remainder of 488.
Use 1 as the next digit of our solution. 
Result so far: 125681.7411
If we take 792 away from 1280, we end up with 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

In conclusion, the division gives 125681.7411 with a balance of 0.00488.
