We divide 150102 by 30
Let's see how many times 30 fits into 150102.

Advancing to step 1:
The number 30 fits into 1 0 times, leaving 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.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 30

Moving on to step 2:
30 goes into 15 0 times with a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Include the next digit (0) from the dividend after 15, then repeat: 150 / 30

Step 3:
The number 30 fits into 150 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 150 from 150 and we're left with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 30

Let's proceed to step 4:
30 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 50.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 30

Going ahead to step 5:
If we divide 10 by 30, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 500.0
If we subtract 0 from 10, we get 10.
Take the next digit (2) from the dividend and append it to 10, then repeat: 102 / 30

On to step 6:
When dividing 102 by 30, we get 3 with a remainder of 12.
The next digit of our result is 3. 
Result so far: 5003.0
The remainder is 12 after subtracting 90 from 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 7:
30 goes into 120 4 times with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 5003.4
Subtracting 120 from 120 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.

Moving on to step 8:
30 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 5003.4
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.

On to step 9:
The number 30 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 5003.4
If we take 0 away from 0, we end up 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.

After the division, we end up with 5003.4 and a remainder of 0.0.
