Let's divide 507575 by 30
We want to figure out the number of times 507575 can be divided by 30.

Advancing to step 1:
30 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 30

Let's proceed to step 2:
When dividing 50 by 30, we get 1 with a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 30 away from 50, we end up with 20.
Fetch the next digit (7) from the dividend, attach it to 20 and continue: 207 / 30

Step 3:
207 divided by 30 is 6 with a remainder of 27.
Use 6 as the next digit of our solution. 
Result so far: 16.0
If we subtract 180 from 207, we get 27.
Fetch the next digit (5) from the dividend, attach it to 27 and continue: 275 / 30

Advancing to step 4:
The number 30 fits into 275 9 times, leaving a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 169.0
Deduct 270 from 275 and we're left with 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 30

Let's proceed to step 5:
When dividing 57 by 30, we get 1 with a remainder of 27.
Write down 1 as next digit of the result. 
Result so far: 1691.0
Deduct 30 from 57 and we're left with 27.
Bring next digit (5) of the dividend behind the 27 and repeat the process: 275 / 30

Going ahead to step 6:
The number 30 fits into 275 9 times, leaving a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 16919.0
If we subtract 270 from 275, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 7:
30 goes into 50 1 times with a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 16919.1
Deduct 30 from 50 and we're left 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 8:
If we divide 200 by 30, we get 6 and a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 16919.16
Deduct 180 from 200 and we're left 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:
If we divide 200 by 30, we get 6 and a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 16919.166
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.

The quotient of the division is 16919.166, and the remainder is 0.002.
