996143 divided by 18 
We're looking to find how many times 18 goes into 996143.

On to step 1:
18 goes into 9 0 times with 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 (9) from the dividend, attach it to 9 and continue: 99 / 18

Going ahead to step 2:
99 divided by 18 is 5 with a remainder of 9.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 90 from 99 to get 9.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 18

On to step 3:
18 can be fit into 96 5 times, resulting in a remainder of 6.
Write down 5 as next digit of the result. 
Result so far: 55.0
If we take 90 away from 96, we end up with 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 18

On to step 4:
18 goes into 61 3 times with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 553.0
Subtract 54 from 61 to get 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 18

Moving on to step 5:
74 divided by 18 is 4 with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 5534.0
If we subtract 72 from 74, we get 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 18

Going ahead to step 6:
18 can be fit into 23 1 times, resulting in a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 55341.0
The remainder is 5 after subtracting 18 from 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
If we divide 50 by 18, we get 2 and a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 55341.2
Deduct 36 from 50 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 8:
When dividing 140 by 18, we get 7 with a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 55341.27
Subtract 126 from 140 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 9:
If we divide 140 by 18, we get 7 and a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 55341.277
Subtracting 126 from 140 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Our division results in 55341.277 with a remaining 0.0014.
