Let's divide 660343 by 30
Let's see how many times 30 fits into 660343.

Advancing to step 1:
30 can be fit into 6 0 times, resulting in 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 (6) from the dividend, add it to 6, then carry on: 66 / 30

Advancing to step 2:
66 divided by 30 is 2 with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 60 away from 66, we end up with 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 30

Step 3:
30 can be fit into 60 2 times, resulting in a remainder of 0.
The next digit of our result is 2. 
Result so far: 22.0
Subtracting 60 from 60 leaves us with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 30

On to step 4:
If we divide 3 by 30, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 220.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 30

Step 5:
34 divided by 30 is 1 with a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 2201.0
Deduct 30 from 34 and we're left with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 30

Going ahead to step 6:
The number 30 fits into 43 1 times, leaving a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 22011.0
Subtracting 30 from 43 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 7:
30 can be fit into 130 4 times, resulting in a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 22011.4
Deduct 120 from 130 and we're left 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.

Advancing to step 8:
100 divided by 30 is 3 with a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 22011.43
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 9:
The number 30 fits into 100 3 times, leaving a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 22011.433
If we subtract 90 from 100, we 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 quotient of the division is 22011.433, and the remainder is 0.001.
