We're dividing 102168 by 30 
Let's see how many times 30 fits into 102168.

Going ahead to step 1:
When dividing 1 by 30, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 30

Let's proceed to step 2:
30 can be fit into 10 0 times, resulting in a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 10, we get 10.
Grab the next digit (2) from the dividend, add it to 10, then carry on: 102 / 30

Moving on to step 3:
The number 30 fits into 102 3 times, leaving a remainder of 12.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 90 from 102 and we're left with 12.
Bring next digit (1) of the dividend behind the 12 and repeat the process: 121 / 30

Step 4:
If we divide 121 by 30, we get 4 and a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 34.0
The remainder is 1 after subtracting 120 from 121.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 30

Moving on to step 5:
30 can be fit into 16 0 times, resulting in a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 340.0
If we take 0 away from 16, we end up with 16.
Append the next digit (8) from the dividend to 16 and continue with: 168 / 30

On to step 6:
The number 30 fits into 168 5 times, leaving a remainder of 18.
The next digit of our result is 5. 
Result so far: 3405.0
Subtract 150 from 168 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 7:
180 divided by 30 is 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 3405.6
Subtracting 180 from 180 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
0 divided by 30 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 3405.6
Subtract 0 from 0 to 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.

Advancing to step 9:
If we divide 0 by 30, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 3405.6
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 3405.6, and the remainder is 0.0.
