Let's divide 8425580 by 30
We want to figure out the number of times 8425580 can be divided by 30.

Step 1:
30 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 30

Going ahead to step 2:
30 can be fit into 84 2 times, resulting in a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 60 from 84 leaves us with 24.
Include the next digit (2) from the dividend after 24, then repeat: 242 / 30

Let's proceed to step 3:
30 goes into 242 8 times with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
Subtracting 240 from 242 leaves us with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 30

On to step 4:
When dividing 25 by 30, we get 0 with a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 280.0
Deduct 0 from 25 and we're left with 25.
Bring next digit (5) of the dividend behind the 25 and repeat the process: 255 / 30

Going ahead to step 5:
255 divided by 30 is 8 with a remainder of 15.
The next digit of our result is 8. 
Result so far: 2808.0
Deduct 240 from 255 and we're left with 15.
Bring next digit (8) of the dividend behind the 15 and repeat the process: 158 / 30

Going ahead to step 6:
30 can be fit into 158 5 times, resulting in a remainder of 8.
The number 5 becomes the next digit in our result. 
Result so far: 28085.0
The remainder is 8 after subtracting 150 from 158.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 30

Advancing to step 7:
30 goes into 80 2 times with a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 280852.0
Subtract 60 from 80 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.

Step 8:
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: 280852.6
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.

On to step 9:
If we divide 200 by 30, we get 6 and a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 280852.66
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.

The final result is 280852.66 with a remainder of 0.02.
