728043 divided by 99 
The aim is to understand the frequency of 99 in 728043.

On to step 1:
The number 99 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 99

Advancing to step 2:
99 goes into 72 0 times with a remainder of 72.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 72, we end up with 72.
Include the next digit (8) from the dividend after 72, then repeat: 728 / 99

Going ahead to step 3:
The number 99 fits into 728 7 times, leaving a remainder of 35.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 693 from 728 to get 35.
Take the next digit (0) from the dividend and append it to 35, then repeat: 350 / 99

Moving on to step 4:
99 goes into 350 3 times with a remainder of 53.
Record the quotient 3 as the next digit in the result. 
Result so far: 73.0
If we take 297 away from 350, we end up with 53.
Grab the next digit (4) from the dividend, add it to 53, then carry on: 534 / 99

Going ahead to step 5:
534 divided by 99 is 5 with a remainder of 39.
The next digit of our result is 5. 
Result so far: 735.0
Subtracting 495 from 534 leaves us with 39.
Bring next digit (3) of the dividend behind the 39 and repeat the process: 393 / 99

Going ahead to step 6:
The number 99 fits into 393 3 times, leaving a remainder of 96.
Use 3 as the next digit of our solution. 
Result so far: 7353.0
Subtracting 297 from 393 leaves us with 96.

Moving on to step 7:
99 goes into 960 9 times with a remainder of 69.
The next digit of our result is 9. 
Result so far: 7353.9
If we subtract 891 from 960, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Going ahead to step 8:
690 divided by 99 is 6 with a remainder of 96.
The next digit of our result is 6. 
Result so far: 7353.96
If we take 594 away from 690, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 9:
If we divide 960 by 99, we get 9 and a remainder of 69.
Record the quotient 9 as the next digit in the result. 
Result so far: 7353.969
Subtracting 891 from 960 leaves us with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Going ahead to step 10:
If we divide 690 by 99, we get 6 and a remainder of 96.
Record the quotient 6 as the next digit in the result. 
Result so far: 7353.9696
Subtract 594 from 690 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 11:
The number 99 fits into 960 9 times, leaving a remainder of 69.
Write down 9 as next digit of the result. 
Result so far: 7353.96969
The remainder is 69 after subtracting 891 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 12:
If we divide 690 by 99, we get 6 and a remainder of 96.
The next digit of our result is 6. 
Result so far: 7353.969696
The remainder is 96 after subtracting 594 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Going ahead to step 13:
When dividing 960 by 99, we get 9 with a remainder of 69.
Record the quotient 9 as the next digit in the result. 
Result so far: 7353.9696969
If we subtract 891 from 960, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 14:
99 goes into 690 6 times with a remainder of 96.
Use 6 as the next digit of our solution. 
Result so far: 7353.96969696
Subtract 594 from 690 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

The quotient of the division is 7353.96969696, and the remainder is 9.6e-08.
