We divide 42513 by 30
Our goal is to divide 42513 by 30.

Advancing to step 1:
4 divided by 30 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 30

Going ahead to step 2:
42 divided by 30 is 1 with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 30 from 42 to get 12.
Include the next digit (5) from the dividend after 12, then repeat: 125 / 30

Advancing to step 3:
125 divided by 30 is 4 with a remainder of 5.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we subtract 120 from 125, we get 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 30

Going ahead to step 4:
51 divided by 30 is 1 with a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 141.0
The remainder is 21 after subtracting 30 from 51.
Append the next digit (3) from the dividend to 21 and continue with: 213 / 30

Let's proceed to step 5:
The number 30 fits into 213 7 times, leaving a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 1417.0
Subtract 210 from 213 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 6:
If we divide 30 by 30, we get 1 and a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1417.1
If we take 30 away from 30, 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.

Advancing to step 7:
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: 1417.1
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.

Step 8:
30 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1417.1
If we subtract 0 from 0, 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.

The final result is 1417.1 with a remainder of 0.0.
