645287 divided by 30 
Let's see how many times 30 fits into 645287.

Advancing to step 1:
30 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 30

On to step 2:
When dividing 64 by 30, we get 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 4 after subtracting 60 from 64.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 30

On to step 3:
30 can be fit into 45 1 times, resulting in a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
If we take 30 away from 45, we end up with 15.
Bring next digit (2) of the dividend behind the 15 and repeat the process: 152 / 30

Going ahead to step 4:
The number 30 fits into 152 5 times, leaving a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 215.0
If we subtract 150 from 152, we get 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 30

Let's proceed to step 5:
30 can be fit into 28 0 times, resulting in a remainder of 28.
The next digit of our result is 0. 
Result so far: 2150.0
Deduct 0 from 28 and we're left with 28.
Fetch the next digit (7) from the dividend, attach it to 28 and continue: 287 / 30

Let's proceed to step 6:
If we divide 287 by 30, we get 9 and a remainder of 17.
Put 9 as the next digit of the answer. 
Result so far: 21509.0
The remainder is 17 after subtracting 270 from 287.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 7:
170 divided by 30 is 5 with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 21509.5
Deduct 150 from 170 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.

Moving on to step 8:
30 goes into 200 6 times with a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 21509.56
Subtract 180 from 200 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.

Going ahead to step 9:
If we divide 200 by 30, we get 6 and a remainder of 20.
The next digit of our result is 6. 
Result so far: 21509.566
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.

Our division results in 21509.566 with a remaining 0.002.
