660986 divided by 20 
Let's see how many times 20 fits into 660986.

Advancing to step 1:
If we divide 6 by 20, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 20

Step 2:
20 can be fit into 66 3 times, resulting in a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 60 from 66 leaves us with 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 20

Advancing to step 3:
The number 20 fits into 60 3 times, leaving a remainder of 0.
The next digit of our result is 3. 
Result so far: 33.0
Subtract 60 from 60 to get 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 20

Advancing to step 4:
20 goes into 9 0 times with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 330.0
If we subtract 0 from 9, we get 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 20

Moving on to step 5:
98 divided by 20 is 4 with a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 3304.0
If we take 80 away from 98, we end up with 18.
Bring next digit (6) of the dividend behind the 18 and repeat the process: 186 / 20

On to step 6:
When dividing 186 by 20, we get 9 with a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 33049.0
Deduct 180 from 186 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 7:
The number 20 fits into 60 3 times, leaving a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 33049.3
If we subtract 60 from 60, 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.

Step 8:
20 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 33049.3
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 33049.3
Subtracting 0 from 0 leaves us with 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 final result is 33049.3 with a remainder of 0.0.
