74923557 divided by 999 
We want to figure out the number of times 74923557 can be divided by 999.

Let's proceed to step 1:
If we divide 7 by 999, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 999

Let's proceed to step 2:
999 can be fit into 74 0 times, resulting in a remainder of 74.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 74, we get 74.
Take the next digit (9) from the dividend and append it to 74, then repeat: 749 / 999

Let's proceed to step 3:
749 divided by 999 is 0 with a remainder of 749.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 749, we end up with 749.
Grab the next digit (2) from the dividend, add it to 749, then carry on: 7492 / 999

Let's proceed to step 4:
999 can be fit into 7492 7 times, resulting in a remainder of 499.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 6993 from 7492, we get 499.
Grab the next digit (3) from the dividend, add it to 499, then carry on: 4993 / 999

Going ahead to step 5:
If we divide 4993 by 999, we get 4 and a remainder of 997.
The number 4 becomes the next digit in our result. 
Result so far: 74.0
Deduct 3996 from 4993 and we're left with 997.
Append the next digit (5) from the dividend to 997 and continue with: 9975 / 999

Step 6:
9975 divided by 999 is 9 with a remainder of 984.
Write down 9 as next digit of the result. 
Result so far: 749.0
The remainder is 984 after subtracting 8991 from 9975.
Append the next digit (5) from the dividend to 984 and continue with: 9845 / 999

Going ahead to step 7:
999 can be fit into 9845 9 times, resulting in a remainder of 854.
Put 9 as the next digit of the answer. 
Result so far: 7499.0
Subtracting 8991 from 9845 leaves us with 854.
Include the next digit (7) from the dividend after 854, then repeat: 8547 / 999

Moving on to step 8:
999 goes into 8547 8 times with a remainder of 555.
Use 8 as the next digit of our solution. 
Result so far: 74998.0
Subtracting 7992 from 8547 leaves us with 555.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5550, and continue the process.

Moving on to step 9:
The number 999 fits into 5550 5 times, leaving a remainder of 555.
Put 5 as the next digit of the answer. 
Result so far: 74998.5
Deduct 4995 from 5550 and we're left with 555.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5550, and continue the process.

Going ahead to step 10:
5550 divided by 999 is 5 with a remainder of 555.
The next digit of our result is 5. 
Result so far: 74998.55
If we take 4995 away from 5550, we end up with 555.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5550, and continue the process.

The final outcome is 74998.55, with a leftover of 0.555.
