668679 divided by 20 
We want to divide 668679 by 20.

Moving on to step 1:
20 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 20

Let's proceed to step 2:
The number 20 fits into 66 3 times, leaving a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 60 from 66 leaves us with 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 20

Let's proceed to step 3:
20 can be fit into 68 3 times, resulting in a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 33.0
Subtracting 60 from 68 leaves us with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 20

Step 4:
20 goes into 86 4 times with a remainder of 6.
The next digit of our result is 4. 
Result so far: 334.0
The remainder is 6 after subtracting 80 from 86.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 20

Let's proceed to step 5:
20 can be fit into 67 3 times, resulting in a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 3343.0
Subtract 60 from 67 to get 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 20

Step 6:
If we divide 79 by 20, we get 3 and a remainder of 19.
Record the quotient 3 as the next digit in the result. 
Result so far: 33433.0
Subtract 60 from 79 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 7:
190 divided by 20 is 9 with a remainder of 10.
Put 9 as the next digit of the answer. 
Result so far: 33433.9
If we take 180 away from 190, we end up 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.

Let's proceed to step 8:
20 can be fit into 100 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 33433.95
If we subtract 100 from 100, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
20 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 33433.95
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
20 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 33433.95
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 33433.95, and the remainder is 0.0.
