We look at the division of 8174578 by 30 
We want to divide 8174578 by 30.

Step 1:
8 divided by 30 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 30

Advancing to step 2:
30 goes into 81 2 times with a remainder of 21.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 21 after subtracting 60 from 81.
Bring next digit (7) of the dividend behind the 21 and repeat the process: 217 / 30

Moving on to step 3:
When dividing 217 by 30, we get 7 with a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
The remainder is 7 after subtracting 210 from 217.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 30

On to step 4:
30 can be fit into 74 2 times, resulting in a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 272.0
Subtract 60 from 74 to get 14.
Bring next digit (5) of the dividend behind the 14 and repeat the process: 145 / 30

Advancing to step 5:
30 can be fit into 145 4 times, resulting in a remainder of 25.
Record the quotient 4 as the next digit in the result. 
Result so far: 2724.0
Deduct 120 from 145 and we're left with 25.
Include the next digit (7) from the dividend after 25, then repeat: 257 / 30

Going ahead to step 6:
The number 30 fits into 257 8 times, leaving a remainder of 17.
Put 8 as the next digit of the answer. 
Result so far: 27248.0
If we subtract 240 from 257, we get 17.
Include the next digit (8) from the dividend after 17, then repeat: 178 / 30

On to step 7:
The number 30 fits into 178 5 times, leaving a remainder of 28.
The number 5 becomes the next digit in our result. 
Result so far: 272485.0
Subtracting 150 from 178 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 8:
30 can be fit into 280 9 times, resulting in a remainder of 10.
Write down 9 as next digit of the result. 
Result so far: 272485.9
Subtracting 270 from 280 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
If we divide 100 by 30, we get 3 and a remainder of 10.
The next digit of our result is 3. 
Result so far: 272485.93
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
30 can be fit into 100 3 times, resulting in a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 272485.933
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 272485.933 and a remainder of 0.001.
