We look at the division of 49066721 by 999 
The aim is to understand the frequency of 999 in 49066721.

On to step 1:
4 divided by 999 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 999

On to step 2:
49 divided by 999 is 0 with a remainder of 49.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 49 after subtracting 0 from 49.
Bring next digit (0) of the dividend behind the 49 and repeat the process: 490 / 999

On to step 3:
999 goes into 490 0 times with a remainder of 490.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 490, we end up with 490.
Include the next digit (6) from the dividend after 490, then repeat: 4906 / 999

The number 999 fits into 4906 4 times, leaving a remainder of 910.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 910 after subtracting 3996 from 4906.
Grab the next digit (6) from the dividend, add it to 910, then carry on: 9106 / 999

Advancing to step 5:
999 can be fit into 9106 9 times, resulting in a remainder of 115.
The next digit of our result is 9. 
Result so far: 49.0
Subtracting 8991 from 9106 leaves us with 115.
Fetch the next digit (7) from the dividend, attach it to 115 and continue: 1157 / 999

Advancing to step 6:
1157 divided by 999 is 1 with a remainder of 158.
The next digit of our result is 1. 
Result so far: 491.0
Subtracting 999 from 1157 leaves us with 158.
Grab the next digit (2) from the dividend, add it to 158, then carry on: 1582 / 999

On to step 7:
When dividing 1582 by 999, we get 1 with a remainder of 583.
Use 1 as the next digit of our solution. 
Result so far: 4911.0
Subtract 999 from 1582 to get 583.
Append the next digit (1) from the dividend to 583 and continue with: 5831 / 999

Let's proceed to step 8:
999 goes into 5831 5 times with a remainder of 836.
The number 5 becomes the next digit in our result. 
Result so far: 49115.0
If we take 4995 away from 5831, we end up with 836.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8360, and continue the process.

Going ahead to step 9:
The number 999 fits into 8360 8 times, leaving a remainder of 368.
Record the quotient 8 as the next digit in the result. 
Result so far: 49115.8
If we subtract 7992 from 8360, we get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Going ahead to step 10:
999 goes into 3680 3 times with a remainder of 683.
The number 3 becomes the next digit in our result. 
Result so far: 49115.83
Subtracting 2997 from 3680 leaves us with 683.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6830, and continue the process.

Going ahead to step 11:
The number 999 fits into 6830 6 times, leaving a remainder of 836.
Record the quotient 6 as the next digit in the result. 
Result so far: 49115.836
Deduct 5994 from 6830 and we're left with 836.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8360, and continue the process.

Moving on to step 12:
If we divide 8360 by 999, we get 8 and a remainder of 368.
Use 8 as the next digit of our solution. 
Result so far: 49115.8368
Subtracting 7992 from 8360 leaves us with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Moving on to step 13:
If we divide 3680 by 999, we get 3 and a remainder of 683.
Write down 3 as next digit of the result. 
Result so far: 49115.83683
The remainder is 683 after subtracting 2997 from 3680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6830, and continue the process.

Moving on to step 14:
6830 divided by 999 is 6 with a remainder of 836.
Record the quotient 6 as the next digit in the result. 
Result so far: 49115.836836
The remainder is 836 after subtracting 5994 from 6830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8360, and continue the process.

Moving on to step 15:
When dividing 8360 by 999, we get 8 with a remainder of 368.
The next digit of our result is 8. 
Result so far: 49115.8368368
If we subtract 7992 from 8360, we get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Let's proceed to step 16:
When dividing 3680 by 999, we get 3 with a remainder of 683.
Use 3 as the next digit of our solution. 
Result so far: 49115.83683683
The remainder is 683 after subtracting 2997 from 3680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6830, and continue the process.

In conclusion, the division gives 49115.83683683 with a balance of 6.83e-07.
