We look at the division of 29892454 by 990 
The aim is to understand the frequency of 990 in 29892454.

Advancing to step 1:
The number 990 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 990

Going ahead to step 2:
990 goes into 29 0 times with a remainder of 29.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 29, we get 29.
Grab the next digit (8) from the dividend, add it to 29, then carry on: 298 / 990

On to step 3:
990 can be fit into 298 0 times, resulting in a remainder of 298.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 298 to get 298.
Fetch the next digit (9) from the dividend, attach it to 298 and continue: 2989 / 990

Step 4:
When dividing 2989 by 990, we get 3 with a remainder of 19.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 2970 from 2989, we get 19.
Include the next digit (2) from the dividend after 19, then repeat: 192 / 990

On to step 5:
990 goes into 192 0 times with a remainder of 192.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
If we take 0 away from 192, we end up with 192.
Include the next digit (4) from the dividend after 192, then repeat: 1924 / 990

On to step 6:
990 can be fit into 1924 1 times, resulting in a remainder of 934.
Record the quotient 1 as the next digit in the result. 
Result so far: 301.0
The remainder is 934 after subtracting 990 from 1924.
Append the next digit (5) from the dividend to 934 and continue with: 9345 / 990

Let's proceed to step 7:
9345 divided by 990 is 9 with a remainder of 435.
Put 9 as the next digit of the answer. 
Result so far: 3019.0
Subtract 8910 from 9345 to get 435.
Fetch the next digit (4) from the dividend, attach it to 435 and continue: 4354 / 990

Step 8:
990 goes into 4354 4 times with a remainder of 394.
Record the quotient 4 as the next digit in the result. 
Result so far: 30194.0
If we take 3960 away from 4354, we end up with 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

On to step 9:
If we divide 3940 by 990, we get 3 and a remainder of 970.
Write down 3 as next digit of the result. 
Result so far: 30194.3
Deduct 2970 from 3940 and we're left with 970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9700, and continue the process.

Let's proceed to step 10:
When dividing 9700 by 990, we get 9 with a remainder of 790.
Write down 9 as next digit of the result. 
Result so far: 30194.39
If we subtract 8910 from 9700, we get 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

Moving on to step 11:
When dividing 7900 by 990, we get 7 with a remainder of 970.
Record the quotient 7 as the next digit in the result. 
Result so far: 30194.397
Deduct 6930 from 7900 and we're left with 970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9700, and continue the process.

On to step 12:
990 goes into 9700 9 times with a remainder of 790.
Use 9 as the next digit of our solution. 
Result so far: 30194.3979
Subtracting 8910 from 9700 leaves us with 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

On to step 13:
7900 divided by 990 is 7 with a remainder of 970.
Write down 7 as next digit of the result. 
Result so far: 30194.39797
If we take 6930 away from 7900, we end up with 970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9700, and continue the process.

Let's proceed to step 14:
990 can be fit into 9700 9 times, resulting in a remainder of 790.
The number 9 becomes the next digit in our result. 
Result so far: 30194.397979
The remainder is 790 after subtracting 8910 from 9700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

Step 15:
7900 divided by 990 is 7 with a remainder of 970.
Use 7 as the next digit of our solution. 
Result so far: 30194.3979797
Deduct 6930 from 7900 and we're left with 970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9700, and continue the process.

On to step 16:
The number 990 fits into 9700 9 times, leaving a remainder of 790.
The next digit of our result is 9. 
Result so far: 30194.39797979
If we take 8910 away from 9700, we end up with 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

The quotient of the division is 30194.39797979, and the remainder is 7.9e-07.
