We look at the division of 216102 by 40 
Our goal is to divide 216102 by 40.

Step 1:
When dividing 2 by 40, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 40

On to step 2:
When dividing 21 by 40, we get 0 with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Take the next digit (6) from the dividend and append it to 21, then repeat: 216 / 40

Let's proceed to step 3:
40 can be fit into 216 5 times, resulting in a remainder of 16.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 200 from 216 and we're left with 16.
Include the next digit (1) from the dividend after 16, then repeat: 161 / 40

Let's proceed to step 4:
When dividing 161 by 40, we get 4 with a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 54.0
Subtracting 160 from 161 leaves us with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 40

Going ahead to step 5:
40 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 540.0
If we take 0 away from 10, we end up with 10.
Grab the next digit (2) from the dividend, add it to 10, then carry on: 102 / 40

Advancing to step 6:
If we divide 102 by 40, we get 2 and a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 5402.0
Deduct 80 from 102 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 7:
40 goes into 220 5 times with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 5402.5
If we subtract 200 from 220, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
200 divided by 40 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 5402.55
If we subtract 200 from 200, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 5402.55 and a remainder of 0.0.
