We look at the division of 29933311 by 999 
The aim is to understand the frequency of 999 in 29933311.

Moving on to step 1:
When dividing 2 by 999, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 999

Step 2:
29 divided by 999 is 0 with a remainder of 29.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 29, we get 29.
Include the next digit (9) from the dividend after 29, then repeat: 299 / 999

On to step 3:
999 can be fit into 299 0 times, resulting in a remainder of 299.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 299, we end up with 299.
Include the next digit (3) from the dividend after 299, then repeat: 2993 / 999

Step 4:
The number 999 fits into 2993 2 times, leaving a remainder of 995.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 995 after subtracting 1998 from 2993.
Append the next digit (3) from the dividend to 995 and continue with: 9953 / 999

Going ahead to step 5:
999 can be fit into 9953 9 times, resulting in a remainder of 962.
Put 9 as the next digit of the answer. 
Result so far: 29.0
Deduct 8991 from 9953 and we're left with 962.
Grab the next digit (3) from the dividend, add it to 962, then carry on: 9623 / 999

Step 6:
The number 999 fits into 9623 9 times, leaving a remainder of 632.
The next digit of our result is 9. 
Result so far: 299.0
The remainder is 632 after subtracting 8991 from 9623.
Fetch the next digit (1) from the dividend, attach it to 632 and continue: 6321 / 999

Advancing to step 7:
If we divide 6321 by 999, we get 6 and a remainder of 327.
The next digit of our result is 6. 
Result so far: 2996.0
If we take 5994 away from 6321, we end up with 327.
Include the next digit (1) from the dividend after 327, then repeat: 3271 / 999

On to step 8:
3271 divided by 999 is 3 with a remainder of 274.
Record the quotient 3 as the next digit in the result. 
Result so far: 29963.0
Deduct 2997 from 3271 and we're left with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Advancing to step 9:
The number 999 fits into 2740 2 times, leaving a remainder of 742.
Write down 2 as next digit of the result. 
Result so far: 29963.2
Subtract 1998 from 2740 to get 742.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7420, and continue the process.

Going ahead to step 10:
7420 divided by 999 is 7 with a remainder of 427.
Write down 7 as next digit of the result. 
Result so far: 29963.27
If we subtract 6993 from 7420, we get 427.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4270, and continue the process.

Advancing to step 11:
When dividing 4270 by 999, we get 4 with a remainder of 274.
Put 4 as the next digit of the answer. 
Result so far: 29963.274
Subtract 3996 from 4270 to get 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Step 12:
999 goes into 2740 2 times with a remainder of 742.
Use 2 as the next digit of our solution. 
Result so far: 29963.2742
The remainder is 742 after subtracting 1998 from 2740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7420, and continue the process.

On to step 13:
999 can be fit into 7420 7 times, resulting in a remainder of 427.
The next digit of our result is 7. 
Result so far: 29963.27427
If we subtract 6993 from 7420, we get 427.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4270, and continue the process.

On to step 14:
The number 999 fits into 4270 4 times, leaving a remainder of 274.
Use 4 as the next digit of our solution. 
Result so far: 29963.274274
Deduct 3996 from 4270 and we're left with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Step 15:
999 goes into 2740 2 times with a remainder of 742.
The next digit of our result is 2. 
Result so far: 29963.2742742
The remainder is 742 after subtracting 1998 from 2740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7420, and continue the process.

Going ahead to step 16:
999 goes into 7420 7 times with a remainder of 427.
The number 7 becomes the next digit in our result. 
Result so far: 29963.27427427
Subtract 6993 from 7420 to get 427.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4270, and continue the process.

The final outcome is 29963.27427427, with a leftover of 4.27e-07.
