Let's divide 75509 by 30
We're looking to find how many times 30 goes into 75509.

Moving on to step 1:
30 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 30

Step 2:
If we divide 75 by 30, we get 2 and a remainder of 15.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 60 away from 75, we end up with 15.
Grab the next digit (5) from the dividend, add it to 15, then carry on: 155 / 30

Advancing to step 3:
If we divide 155 by 30, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 25.0
The remainder is 5 after subtracting 150 from 155.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 30

Moving on to step 4:
When dividing 50 by 30, we get 1 with a remainder of 20.
The next digit of our result is 1. 
Result so far: 251.0
Subtracting 30 from 50 leaves us with 20.
Grab the next digit (9) from the dividend, add it to 20, then carry on: 209 / 30

Advancing to step 5:
30 can be fit into 209 6 times, resulting in a remainder of 29.
Put 6 as the next digit of the answer. 
Result so far: 2516.0
The remainder is 29 after subtracting 180 from 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 6:
If we divide 290 by 30, we get 9 and a remainder of 20.
Write down 9 as next digit of the result. 
Result so far: 2516.9
Deduct 270 from 290 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.

Step 7:
30 goes into 200 6 times with a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 2516.96
Subtracting 180 from 200 leaves us 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 8:
200 divided by 30 is 6 with a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 2516.966
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 final result is 2516.966 with a remainder of 0.002.
