74885084 divided by 999 
The aim is to understand the frequency of 999 in 74885084.

Advancing to step 1:
7 divided by 999 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 999

Let's proceed to step 2:
When dividing 74 by 999, we get 0 with a remainder of 74.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 74 and we're left with 74.
Grab the next digit (8) from the dividend, add it to 74, then carry on: 748 / 999

Step 3:
999 can be fit into 748 0 times, resulting in a remainder of 748.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 748, we get 748.
Take the next digit (8) from the dividend and append it to 748, then repeat: 7488 / 999

Step 4:
When dividing 7488 by 999, we get 7 with a remainder of 495.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 495 after subtracting 6993 from 7488.
Bring next digit (5) of the dividend behind the 495 and repeat the process: 4955 / 999

Let's proceed to step 5:
999 goes into 4955 4 times with a remainder of 959.
The next digit of our result is 4. 
Result so far: 74.0
Deduct 3996 from 4955 and we're left with 959.
Include the next digit (0) from the dividend after 959, then repeat: 9590 / 999

Let's proceed to step 6:
The number 999 fits into 9590 9 times, leaving a remainder of 599.
Put 9 as the next digit of the answer. 
Result so far: 749.0
The remainder is 599 after subtracting 8991 from 9590.
Take the next digit (8) from the dividend and append it to 599, then repeat: 5998 / 999

Step 7:
When dividing 5998 by 999, we get 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 7496.0
Subtract 5994 from 5998 to get 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 999

On to step 8:
When dividing 44 by 999, we get 0 with a remainder of 44.
Record the quotient 0 as the next digit in the result. 
Result so far: 74960.0
If we subtract 0 from 44, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 9:
If we divide 440 by 999, we get 0 and a remainder of 440.
Put 0 as the next digit of the answer. 
Result so far: 74960.0
Deduct 0 from 440 and we're left with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Let's proceed to step 10:
999 can be fit into 4400 4 times, resulting in a remainder of 404.
Write down 4 as next digit of the result. 
Result so far: 74960.04
Subtract 3996 from 4400 to get 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Step 11:
When dividing 4040 by 999, we get 4 with a remainder of 44.
Use 4 as the next digit of our solution. 
Result so far: 74960.044
If we take 3996 away from 4040, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The final result is 74960.044 with a remainder of 0.0044.
