We divide 78249289 by 999
We want to figure out the number of times 78249289 can be divided by 999.

Step 1:
999 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 999

Advancing to step 2:
The number 999 fits into 78 0 times, leaving a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Append the next digit (2) from the dividend to 78 and continue with: 782 / 999

Step 3:
If we divide 782 by 999, we get 0 and a remainder of 782.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 782, we get 782.
Include the next digit (4) from the dividend after 782, then repeat: 7824 / 999

Moving on to step 4:
If we divide 7824 by 999, we get 7 and a remainder of 831.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 6993 away from 7824, we end up with 831.
Bring next digit (9) of the dividend behind the 831 and repeat the process: 8319 / 999

Let's proceed to step 5:
999 can be fit into 8319 8 times, resulting in a remainder of 327.
The next digit of our result is 8. 
Result so far: 78.0
If we subtract 7992 from 8319, we get 327.
Take the next digit (2) from the dividend and append it to 327, then repeat: 3272 / 999

Advancing to step 6:
3272 divided by 999 is 3 with a remainder of 275.
Use 3 as the next digit of our solution. 
Result so far: 783.0
The remainder is 275 after subtracting 2997 from 3272.
Take the next digit (8) from the dividend and append it to 275, then repeat: 2758 / 999

Going ahead to step 7:
When dividing 2758 by 999, we get 2 with a remainder of 760.
The next digit of our result is 2. 
Result so far: 7832.0
Deduct 1998 from 2758 and we're left with 760.
Fetch the next digit (9) from the dividend, attach it to 760 and continue: 7609 / 999

On to step 8:
The number 999 fits into 7609 7 times, leaving a remainder of 616.
Write down 7 as next digit of the result. 
Result so far: 78327.0
If we take 6993 away from 7609, we end up with 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

Step 9:
6160 divided by 999 is 6 with a remainder of 166.
Use 6 as the next digit of our solution. 
Result so far: 78327.6
If we subtract 5994 from 6160, we get 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Moving on to step 10:
The number 999 fits into 1660 1 times, leaving a remainder of 661.
Put 1 as the next digit of the answer. 
Result so far: 78327.61
Subtract 999 from 1660 to get 661.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6610, and continue the process.

Advancing to step 11:
When dividing 6610 by 999, we get 6 with a remainder of 616.
Write down 6 as next digit of the result. 
Result so far: 78327.616
If we subtract 5994 from 6610, we get 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

Let's proceed to step 12:
The number 999 fits into 6160 6 times, leaving a remainder of 166.
The next digit of our result is 6. 
Result so far: 78327.6166
The remainder is 166 after subtracting 5994 from 6160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

The quotient of the division is 78327.6166, and the remainder is 0.00166.
