We look at the division of 644824 by 30 
We want to figure out the number of times 644824 can be divided by 30.

Moving on to step 1:
6 divided by 30 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 30

Going ahead to step 2:
30 can be fit into 64 2 times, resulting in a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 60 from 64 and we're left with 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 30

On to step 3:
30 goes into 44 1 times with a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 21.0
If we subtract 30 from 44, we get 14.
Include the next digit (8) from the dividend after 14, then repeat: 148 / 30

Moving on to step 4:
When dividing 148 by 30, we get 4 with a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 214.0
If we subtract 120 from 148, we get 28.
Take the next digit (2) from the dividend and append it to 28, then repeat: 282 / 30

Let's proceed to step 5:
30 goes into 282 9 times with a remainder of 12.
Use 9 as the next digit of our solution. 
Result so far: 2149.0
The remainder is 12 after subtracting 270 from 282.
Include the next digit (4) from the dividend after 12, then repeat: 124 / 30

On to step 6:
124 divided by 30 is 4 with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 21494.0
Subtract 120 from 124 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
30 goes into 40 1 times with a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 21494.1
Subtract 30 from 40 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.

Moving on to step 8:
100 divided by 30 is 3 with a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 21494.13
Subtracting 90 from 100 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.

Moving on to step 9:
The number 30 fits into 100 3 times, leaving a remainder of 10.
The next digit of our result is 3. 
Result so far: 21494.133
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.

The final result is 21494.133 with a remainder of 0.001.
