We divide 990469 by 99
The aim is to understand the frequency of 99 in 990469.

On to step 1:
99 can be fit into 9 0 times, resulting in a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 99

Let's proceed to step 2:
99 divided by 99 is 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 99 away from 99, we end up with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 99

Advancing to step 3:
When dividing 0 by 99, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 10.0
Subtract 0 from 0 to get 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 99

Let's proceed to step 4:
99 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 100.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (6) of the dividend behind the 4 and repeat the process: 46 / 99

Advancing to step 5:
If we divide 46 by 99, we get 0 and a remainder of 46.
Write down 0 as next digit of the result. 
Result so far: 1000.0
If we subtract 0 from 46, we get 46.
Grab the next digit (9) from the dividend, add it to 46, then carry on: 469 / 99

Moving on to step 6:
When dividing 469 by 99, we get 4 with a remainder of 73.
Record the quotient 4 as the next digit in the result. 
Result so far: 10004.0
Subtracting 396 from 469 leaves us with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Moving on to step 7:
If we divide 730 by 99, we get 7 and a remainder of 37.
Use 7 as the next digit of our solution. 
Result so far: 10004.7
Subtracting 693 from 730 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 8:
If we divide 370 by 99, we get 3 and a remainder of 73.
The number 3 becomes the next digit in our result. 
Result so far: 10004.73
Subtract 297 from 370 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 9:
The number 99 fits into 730 7 times, leaving a remainder of 37.
Put 7 as the next digit of the answer. 
Result so far: 10004.737
Deduct 693 from 730 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 10:
99 goes into 370 3 times with a remainder of 73.
Use 3 as the next digit of our solution. 
Result so far: 10004.7373
If we take 297 away from 370, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 11:
If we divide 730 by 99, we get 7 and a remainder of 37.
The next digit of our result is 7. 
Result so far: 10004.73737
If we take 693 away from 730, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 12:
370 divided by 99 is 3 with a remainder of 73.
The number 3 becomes the next digit in our result. 
Result so far: 10004.737373
If we subtract 297 from 370, we get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Advancing to step 13:
When dividing 730 by 99, we get 7 with a remainder of 37.
Write down 7 as next digit of the result. 
Result so far: 10004.7373737
The remainder is 37 after subtracting 693 from 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 14:
The number 99 fits into 370 3 times, leaving a remainder of 73.
Record the quotient 3 as the next digit in the result. 
Result so far: 10004.73737373
Deduct 297 from 370 and we're left with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

The final result is 10004.73737373 with a remainder of 7.3e-08.
