We're dividing 52487 by 30 
We want to figure out the number of times 52487 can be divided by 30.

Step 1:
5 divided by 30 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 30

On to step 2:
When dividing 52 by 30, we get 1 with a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 30 from 52, we get 22.
Take the next digit (4) from the dividend and append it to 22, then repeat: 224 / 30

Let's proceed to step 3:
30 can be fit into 224 7 times, resulting in a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Subtracting 210 from 224 leaves us with 14.
Take the next digit (8) from the dividend and append it to 14, then repeat: 148 / 30

Let's proceed to step 4:
The number 30 fits into 148 4 times, leaving a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 174.0
Subtracting 120 from 148 leaves us with 28.
Include the next digit (7) from the dividend after 28, then repeat: 287 / 30

Going ahead to step 5:
30 can be fit into 287 9 times, resulting in a remainder of 17.
The number 9 becomes the next digit in our result. 
Result so far: 1749.0
Subtract 270 from 287 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 6:
When dividing 170 by 30, we get 5 with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 1749.5
If we take 150 away from 170, 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.

Step 7:
When dividing 200 by 30, we get 6 with a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 1749.56
If we take 180 away from 200, 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.

On to step 8:
When dividing 200 by 30, we get 6 with a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 1749.566
If we subtract 180 from 200, we 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.

Our division results in 1749.566 with a remaining 0.002.
