We look at the division of 71368 by 18 
We're looking to find how many times 18 goes into 71368.

On to step 1:
7 divided by 18 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 18

Advancing to step 2:
The number 18 fits into 71 3 times, leaving a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 54 from 71 to get 17.
Grab the next digit (3) from the dividend, add it to 17, then carry on: 173 / 18

Advancing to step 3:
When dividing 173 by 18, we get 9 with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
If we take 162 away from 173, we end up with 11.
Grab the next digit (6) from the dividend, add it to 11, then carry on: 116 / 18

Let's proceed to step 4:
18 can be fit into 116 6 times, resulting in a remainder of 8.
The next digit of our result is 6. 
Result so far: 396.0
If we take 108 away from 116, we end up with 8.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 18

Moving on to step 5:
88 divided by 18 is 4 with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 3964.0
If we subtract 72 from 88, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 6:
The number 18 fits into 160 8 times, leaving a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 3964.8
Subtract 144 from 160 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 7:
The number 18 fits into 160 8 times, leaving a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 3964.88
Deduct 144 from 160 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 3964.88 with a remaining 0.016.
