697304 ÷ 99 
The aim is to understand the frequency of 99 in 697304.

Going ahead to step 1:
If we divide 6 by 99, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 99

Moving on to step 2:
The number 99 fits into 69 0 times, leaving a remainder of 69.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 69, we end up with 69.
Grab the next digit (7) from the dividend, add it to 69, then carry on: 697 / 99

Going ahead to step 3:
697 divided by 99 is 7 with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 693 from 697, we get 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 99

Step 4:
99 goes into 43 0 times with a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 70.0
The remainder is 43 after subtracting 0 from 43.
Include the next digit (0) from the dividend after 43, then repeat: 430 / 99

Going ahead to step 5:
430 divided by 99 is 4 with a remainder of 34.
The next digit of our result is 4. 
Result so far: 704.0
Subtracting 396 from 430 leaves us with 34.
Include the next digit (4) from the dividend after 34, then repeat: 344 / 99

Moving on to step 6:
If we divide 344 by 99, we get 3 and a remainder of 47.
Record the quotient 3 as the next digit in the result. 
Result so far: 7043.0
If we take 297 away from 344, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 7:
The number 99 fits into 470 4 times, leaving a remainder of 74.
Record the quotient 4 as the next digit in the result. 
Result so far: 7043.4
The remainder is 74 after subtracting 396 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 8:
If we divide 740 by 99, we get 7 and a remainder of 47.
The next digit of our result is 7. 
Result so far: 7043.47
If we subtract 693 from 740, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 9:
99 can be fit into 470 4 times, resulting in a remainder of 74.
Use 4 as the next digit of our solution. 
Result so far: 7043.474
The remainder is 74 after subtracting 396 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 10:
The number 99 fits into 740 7 times, leaving a remainder of 47.
Write down 7 as next digit of the result. 
Result so far: 7043.4747
If we subtract 693 from 740, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 11:
The number 99 fits into 470 4 times, leaving a remainder of 74.
Use 4 as the next digit of our solution. 
Result so far: 7043.47474
If we subtract 396 from 470, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 12:
If we divide 740 by 99, we get 7 and a remainder of 47.
The next digit of our result is 7. 
Result so far: 7043.474747
If we take 693 away from 740, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 13:
99 goes into 470 4 times with a remainder of 74.
Record the quotient 4 as the next digit in the result. 
Result so far: 7043.4747474
The remainder is 74 after subtracting 396 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 14:
99 goes into 740 7 times with a remainder of 47.
Use 7 as the next digit of our solution. 
Result so far: 7043.47474747
Subtracting 693 from 740 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

The final result is 7043.47474747 with a remainder of 4.7e-08.
