We divide 141512 by 30
Our goal is to divide 141512 by 30.

Let's proceed 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.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 30

Advancing to step 2:
When dividing 14 by 30, we get 0 with a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 14 and we're left with 14.
Include the next digit (1) from the dividend after 14, then repeat: 141 / 30

Going ahead to step 3:
If we divide 141 by 30, we get 4 and a remainder of 21.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 120 from 141, we get 21.
Fetch the next digit (5) from the dividend, attach it to 21 and continue: 215 / 30

Going ahead to step 4:
When dividing 215 by 30, we get 7 with a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 47.0
The remainder is 5 after subtracting 210 from 215.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 30

Step 5:
30 goes into 51 1 times with a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 471.0
Subtracting 30 from 51 leaves us with 21.
Fetch the next digit (2) from the dividend, attach it to 21 and continue: 212 / 30

Let's proceed to step 6:
The number 30 fits into 212 7 times, leaving a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 4717.0
Subtracting 210 from 212 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
20 divided by 30 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 4717.0
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
200 divided by 30 is 6 with a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 4717.06
Subtracting 180 from 200 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
When dividing 200 by 30, we get 6 with a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 4717.066
Subtracting 180 from 200 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 4717.066, with a leftover of 0.002.
