98618140 ÷ 999 
We want to figure out the number of times 98618140 can be divided by 999.

On to step 1:
If we divide 9 by 999, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 999

On to step 2:
98 divided by 999 is 0 with a remainder of 98.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 98 and we're left with 98.
Append the next digit (6) from the dividend to 98 and continue with: 986 / 999

Going ahead to step 3:
999 goes into 986 0 times with a remainder of 986.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 986, we get 986.
Grab the next digit (1) from the dividend, add it to 986, then carry on: 9861 / 999

Going ahead to step 4:
999 can be fit into 9861 9 times, resulting in a remainder of 870.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 8991 from 9861 to get 870.
Take the next digit (8) from the dividend and append it to 870, then repeat: 8708 / 999

Step 5:
The number 999 fits into 8708 8 times, leaving a remainder of 716.
The number 8 becomes the next digit in our result. 
Result so far: 98.0
Deduct 7992 from 8708 and we're left with 716.
Bring next digit (1) of the dividend behind the 716 and repeat the process: 7161 / 999

Advancing to step 6:
999 can be fit into 7161 7 times, resulting in a remainder of 168.
Use 7 as the next digit of our solution. 
Result so far: 987.0
Deduct 6993 from 7161 and we're left with 168.
Append the next digit (4) from the dividend to 168 and continue with: 1684 / 999

Advancing to step 7:
The number 999 fits into 1684 1 times, leaving a remainder of 685.
Write down 1 as next digit of the result. 
Result so far: 9871.0
If we subtract 999 from 1684, we get 685.
Take the next digit (0) from the dividend and append it to 685, then repeat: 6850 / 999

On to step 8:
6850 divided by 999 is 6 with a remainder of 856.
Record the quotient 6 as the next digit in the result. 
Result so far: 98716.0
Subtracting 5994 from 6850 leaves us with 856.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8560, and continue the process.

Moving on to step 9:
If we divide 8560 by 999, we get 8 and a remainder of 568.
Record the quotient 8 as the next digit in the result. 
Result so far: 98716.8
If we subtract 7992 from 8560, we get 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

Moving on to step 10:
The number 999 fits into 5680 5 times, leaving a remainder of 685.
Put 5 as the next digit of the answer. 
Result so far: 98716.85
If we subtract 4995 from 5680, we get 685.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6850, and continue the process.

Moving on to step 11:
999 goes into 6850 6 times with a remainder of 856.
Use 6 as the next digit of our solution. 
Result so far: 98716.856
Deduct 5994 from 6850 and we're left with 856.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8560, and continue the process.

Moving on to step 12:
If we divide 8560 by 999, we get 8 and a remainder of 568.
The next digit of our result is 8. 
Result so far: 98716.8568
If we take 7992 away from 8560, we end up with 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

On to step 13:
999 can be fit into 5680 5 times, resulting in a remainder of 685.
The number 5 becomes the next digit in our result. 
Result so far: 98716.85685
If we subtract 4995 from 5680, we get 685.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6850, and continue the process.

Let's proceed to step 14:
999 can be fit into 6850 6 times, resulting in a remainder of 856.
Put 6 as the next digit of the answer. 
Result so far: 98716.856856
If we subtract 5994 from 6850, we get 856.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8560, and continue the process.

Going ahead to step 15:
999 goes into 8560 8 times with a remainder of 568.
Record the quotient 8 as the next digit in the result. 
Result so far: 98716.8568568
If we subtract 7992 from 8560, we get 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

Step 16:
5680 divided by 999 is 5 with a remainder of 685.
The number 5 becomes the next digit in our result. 
Result so far: 98716.85685685
Subtracting 4995 from 5680 leaves us with 685.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6850, and continue the process.

The quotient of the division is 98716.85685685, and the remainder is 6.85e-07.
