8211425 ÷ 30 
We want to figure out the number of times 8211425 can be divided by 30.

Let's proceed to step 1:
30 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 30

Let's proceed to step 2:
82 divided by 30 is 2 with a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 60 from 82, we get 22.
Grab the next digit (1) from the dividend, add it to 22, then carry on: 221 / 30

Let's proceed to step 3:
30 can be fit into 221 7 times, resulting in a remainder of 11.
Write down 7 as next digit of the result. 
Result so far: 27.0
If we subtract 210 from 221, we get 11.
Bring next digit (1) of the dividend behind the 11 and repeat the process: 111 / 30

Moving on to step 4:
30 goes into 111 3 times with a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 273.0
Subtract 90 from 111 to get 21.
Take the next digit (4) from the dividend and append it to 21, then repeat: 214 / 30

Let's proceed to step 5:
30 can be fit into 214 7 times, resulting in a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 2737.0
Subtracting 210 from 214 leaves us with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 30

On to step 6:
The number 30 fits into 42 1 times, leaving a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 27371.0
Subtracting 30 from 42 leaves us with 12.
Grab the next digit (5) from the dividend, add it to 12, then carry on: 125 / 30

Step 7:
When dividing 125 by 30, we get 4 with a remainder of 5.
The next digit of our result is 4. 
Result so far: 273714.0
Subtract 120 from 125 to 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.

Advancing to step 8:
30 can be fit into 50 1 times, resulting in a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 273714.1
If we take 30 away from 50, 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 9:
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: 273714.16
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 10:
200 divided by 30 is 6 with a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 273714.166
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.

After the division, we end up with 273714.166 and a remainder of 0.002.
