Let's divide 29302910 by 990
The aim is to understand the frequency of 990 in 29302910.

Advancing to step 1:
990 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 990

Advancing to step 2:
The number 990 fits into 29 0 times, leaving a remainder of 29.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 29 to get 29.
Bring next digit (3) of the dividend behind the 29 and repeat the process: 293 / 990

Let's proceed to step 3:
990 goes into 293 0 times with a remainder of 293.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 293 after subtracting 0 from 293.
Append the next digit (0) from the dividend to 293 and continue with: 2930 / 990

Step 4:
When dividing 2930 by 990, we get 2 with a remainder of 950.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 1980 from 2930, we get 950.
Bring next digit (2) of the dividend behind the 950 and repeat the process: 9502 / 990

On to step 5:
The number 990 fits into 9502 9 times, leaving a remainder of 592.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
If we take 8910 away from 9502, we end up with 592.
Bring next digit (9) of the dividend behind the 592 and repeat the process: 5929 / 990

Let's proceed to step 6:
990 goes into 5929 5 times with a remainder of 979.
The next digit of our result is 5. 
Result so far: 295.0
If we subtract 4950 from 5929, we get 979.
Include the next digit (1) from the dividend after 979, then repeat: 9791 / 990

Going ahead to step 7:
990 can be fit into 9791 9 times, resulting in a remainder of 881.
Write down 9 as next digit of the result. 
Result so far: 2959.0
If we subtract 8910 from 9791, we get 881.
Fetch the next digit (0) from the dividend, attach it to 881 and continue: 8810 / 990

Step 8:
990 goes into 8810 8 times with a remainder of 890.
Record the quotient 8 as the next digit in the result. 
Result so far: 29598.0
Subtract 7920 from 8810 to get 890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8900, and continue the process.

Going ahead to step 9:
When dividing 8900 by 990, we get 8 with a remainder of 980.
Put 8 as the next digit of the answer. 
Result so far: 29598.8
The remainder is 980 after subtracting 7920 from 8900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9800, and continue the process.

Going ahead to step 10:
If we divide 9800 by 990, we get 9 and a remainder of 890.
The next digit of our result is 9. 
Result so far: 29598.89
Subtract 8910 from 9800 to get 890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8900, and continue the process.

Let's proceed to step 11:
8900 divided by 990 is 8 with a remainder of 980.
Put 8 as the next digit of the answer. 
Result so far: 29598.898
The remainder is 980 after subtracting 7920 from 8900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9800, and continue the process.

Step 12:
9800 divided by 990 is 9 with a remainder of 890.
Put 9 as the next digit of the answer. 
Result so far: 29598.8989
The remainder is 890 after subtracting 8910 from 9800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8900, and continue the process.

Step 13:
The number 990 fits into 8900 8 times, leaving a remainder of 980.
The number 8 becomes the next digit in our result. 
Result so far: 29598.89898
If we take 7920 away from 8900, we end up with 980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9800, and continue the process.

Step 14:
990 goes into 9800 9 times with a remainder of 890.
The next digit of our result is 9. 
Result so far: 29598.898989
If we subtract 8910 from 9800, we get 890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8900, and continue the process.

Moving on to step 15:
If we divide 8900 by 990, we get 8 and a remainder of 980.
The number 8 becomes the next digit in our result. 
Result so far: 29598.8989898
The remainder is 980 after subtracting 7920 from 8900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9800, and continue the process.

Advancing to step 16:
When dividing 9800 by 990, we get 9 with a remainder of 890.
Write down 9 as next digit of the result. 
Result so far: 29598.89898989
Deduct 8910 from 9800 and we're left with 890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8900, and continue the process.

The final outcome is 29598.89898989, with a leftover of 8.9e-07.
