We're dividing 521535 by 30 
Let's see how many times 30 fits into 521535.

Going ahead to step 1:
30 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 30

Moving on to step 2:
If we divide 52 by 30, we get 1 and a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 30 away from 52, we end up with 22.
Include the next digit (1) from the dividend after 22, then repeat: 221 / 30

Step 3:
When dividing 221 by 30, we get 7 with a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
If we take 210 away from 221, we end up with 11.
Fetch the next digit (5) from the dividend, attach it to 11 and continue: 115 / 30

Step 4:
115 divided by 30 is 3 with a remainder of 25.
Use 3 as the next digit of our solution. 
Result so far: 173.0
If we subtract 90 from 115, we get 25.
Take the next digit (3) from the dividend and append it to 25, then repeat: 253 / 30

Moving on to step 5:
If we divide 253 by 30, we get 8 and a remainder of 13.
The next digit of our result is 8. 
Result so far: 1738.0
If we subtract 240 from 253, we get 13.
Include the next digit (5) from the dividend after 13, then repeat: 135 / 30

Let's proceed to step 6:
The number 30 fits into 135 4 times, leaving a remainder of 15.
Use 4 as the next digit of our solution. 
Result so far: 17384.0
Subtracting 120 from 135 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 7:
If we divide 150 by 30, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 17384.5
If we take 150 away from 150, 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.

Let's proceed to step 8:
0 divided by 30 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 17384.5
The remainder is 0 after subtracting 0 from 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:
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: 17384.5
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 17384.5 with a remaining 0.0.
