We divide 17998387 by 999
Let's see how many times 999 fits into 17998387.

On to step 1:
The number 999 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 999

Advancing to step 2:
The number 999 fits into 17 0 times, leaving a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 17 after subtracting 0 from 17.
Grab the next digit (9) from the dividend, add it to 17, then carry on: 179 / 999

Advancing to step 3:
999 goes into 179 0 times with a remainder of 179.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 179, we get 179.
Append the next digit (9) from the dividend to 179 and continue with: 1799 / 999

Let's proceed to step 4:
When dividing 1799 by 999, we get 1 with a remainder of 800.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 999 away from 1799, we end up with 800.
Include the next digit (8) from the dividend after 800, then repeat: 8008 / 999

Moving on to step 5:
999 goes into 8008 8 times with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 18.0
Subtracting 7992 from 8008 leaves us with 16.
Take the next digit (3) from the dividend and append it to 16, then repeat: 163 / 999

Let's proceed to step 6:
If we divide 163 by 999, we get 0 and a remainder of 163.
Record the quotient 0 as the next digit in the result. 
Result so far: 180.0
If we take 0 away from 163, we end up with 163.
Bring next digit (8) of the dividend behind the 163 and repeat the process: 1638 / 999

Advancing to step 7:
1638 divided by 999 is 1 with a remainder of 639.
Write down 1 as next digit of the result. 
Result so far: 1801.0
Deduct 999 from 1638 and we're left with 639.
Fetch the next digit (7) from the dividend, attach it to 639 and continue: 6397 / 999

Going ahead to step 8:
999 goes into 6397 6 times with a remainder of 403.
Write down 6 as next digit of the result. 
Result so far: 18016.0
The remainder is 403 after subtracting 5994 from 6397.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4030, and continue the process.

Going ahead to step 9:
999 can be fit into 4030 4 times, resulting in a remainder of 34.
Write down 4 as next digit of the result. 
Result so far: 18016.4
Subtract 3996 from 4030 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 10:
999 can be fit into 340 0 times, resulting in a remainder of 340.
Use 0 as the next digit of our solution. 
Result so far: 18016.4
Subtract 0 from 340 to get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Let's proceed to step 11:
3400 divided by 999 is 3 with a remainder of 403.
The number 3 becomes the next digit in our result. 
Result so far: 18016.403
Deduct 2997 from 3400 and we're left with 403.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4030, and continue the process.

Let's proceed to step 12:
4030 divided by 999 is 4 with a remainder of 34.
Record the quotient 4 as the next digit in the result. 
Result so far: 18016.4034
Subtract 3996 from 4030 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 13:
If we divide 340 by 999, we get 0 and a remainder of 340.
The next digit of our result is 0. 
Result so far: 18016.4034
If we subtract 0 from 340, we get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Advancing to step 14:
999 can be fit into 3400 3 times, resulting in a remainder of 403.
Use 3 as the next digit of our solution. 
Result so far: 18016.403403
If we subtract 2997 from 3400, we get 403.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4030, and continue the process.

Moving on to step 15:
If we divide 4030 by 999, we get 4 and a remainder of 34.
The next digit of our result is 4. 
Result so far: 18016.4034034
Subtract 3996 from 4030 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 16:
When dividing 340 by 999, we get 0 with a remainder of 340.
Write down 0 as next digit of the result. 
Result so far: 18016.4034034
Subtract 0 from 340 to get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

In conclusion, the division gives 18016.4034034 with a balance of 3.4e-07.
