We're dividing 515948 by 30 
Let's see how many times 30 fits into 515948.

Let's proceed to step 1:
5 divided by 30 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 30

Let's proceed to step 2:
30 goes into 51 1 times with a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 30 away from 51, we end up with 21.
Grab the next digit (5) from the dividend, add it to 21, then carry on: 215 / 30

Going ahead to step 3:
If we divide 215 by 30, we get 7 and a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 17.0
If we take 210 away from 215, we end up with 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 30

Going ahead to step 4:
59 divided by 30 is 1 with a remainder of 29.
The next digit of our result is 1. 
Result so far: 171.0
Subtracting 30 from 59 leaves us with 29.
Include the next digit (4) from the dividend after 29, then repeat: 294 / 30

Let's proceed to step 5:
294 divided by 30 is 9 with a remainder of 24.
Use 9 as the next digit of our solution. 
Result so far: 1719.0
If we subtract 270 from 294, we get 24.
Fetch the next digit (8) from the dividend, attach it to 24 and continue: 248 / 30

Step 6:
If we divide 248 by 30, we get 8 and a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 17198.0
Subtract 240 from 248 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 7:
If we divide 80 by 30, we get 2 and a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 17198.2
If we take 60 away from 80, 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.

Going ahead to step 8:
30 can be fit into 200 6 times, resulting in a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 17198.26
The remainder is 20 after subtracting 180 from 200.
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 9:
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: 17198.266
Subtract 180 from 200 to 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.

After the division, we end up with 17198.266 and a remainder of 0.002.
