We look at the division of 50930903 by 999 
The aim is to understand the frequency of 999 in 50930903.

Let's proceed to step 1:
999 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 999

Advancing to step 2:
50 divided by 999 is 0 with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 50, we end up with 50.
Take the next digit (9) from the dividend and append it to 50, then repeat: 509 / 999

Advancing to step 3:
509 divided by 999 is 0 with a remainder of 509.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 509, we end up with 509.
Append the next digit (3) from the dividend to 509 and continue with: 5093 / 999

Advancing to step 4:
The number 999 fits into 5093 5 times, leaving a remainder of 98.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we take 4995 away from 5093, we end up with 98.
Include the next digit (0) from the dividend after 98, then repeat: 980 / 999

Step 5:
If we divide 980 by 999, we get 0 and a remainder of 980.
Use 0 as the next digit of our solution. 
Result so far: 50.0
If we take 0 away from 980, we end up with 980.
Take the next digit (9) from the dividend and append it to 980, then repeat: 9809 / 999

Let's proceed to step 6:
999 can be fit into 9809 9 times, resulting in a remainder of 818.
Record the quotient 9 as the next digit in the result. 
Result so far: 509.0
Subtract 8991 from 9809 to get 818.
Bring next digit (0) of the dividend behind the 818 and repeat the process: 8180 / 999

Going ahead to step 7:
The number 999 fits into 8180 8 times, leaving a remainder of 188.
The next digit of our result is 8. 
Result so far: 5098.0
The remainder is 188 after subtracting 7992 from 8180.
Grab the next digit (3) from the dividend, add it to 188, then carry on: 1883 / 999

Moving on to step 8:
999 goes into 1883 1 times with a remainder of 884.
Record the quotient 1 as the next digit in the result. 
Result so far: 50981.0
If we take 999 away from 1883, we end up with 884.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8840, and continue the process.

On to step 9:
When dividing 8840 by 999, we get 8 with a remainder of 848.
The next digit of our result is 8. 
Result so far: 50981.8
If we take 7992 away from 8840, we end up with 848.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8480, and continue the process.

Let's proceed to step 10:
8480 divided by 999 is 8 with a remainder of 488.
Put 8 as the next digit of the answer. 
Result so far: 50981.88
If we subtract 7992 from 8480, we get 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

In conclusion, the division gives 50981.88 with a balance of 0.488.
