671290 ÷ 20 
We want to divide 671290 by 20.

Advancing to step 1:
The number 20 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 20

Let's proceed to step 2:
20 goes into 67 3 times with a remainder of 7.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 60 from 67 to get 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 20

Step 3:
20 goes into 71 3 times with a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 33.0
If we take 60 away from 71, we end up with 11.
Append the next digit (2) from the dividend to 11 and continue with: 112 / 20

On to step 4:
112 divided by 20 is 5 with a remainder of 12.
Record the quotient 5 as the next digit in the result. 
Result so far: 335.0
The remainder is 12 after subtracting 100 from 112.
Grab the next digit (9) from the dividend, add it to 12, then carry on: 129 / 20

Let's proceed to step 5:
If we divide 129 by 20, we get 6 and a remainder of 9.
The number 6 becomes the next digit in our result. 
Result so far: 3356.0
If we take 120 away from 129, we end up with 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 20

Moving on to step 6:
The number 20 fits into 90 4 times, leaving a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 33564.0
The remainder is 10 after subtracting 80 from 90.
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 7:
20 can be fit into 100 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 33564.5
Subtracting 100 from 100 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.

Let's proceed to step 8:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 33564.5
If we take 0 away from 0, we end up 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.

Step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 33564.5
Deduct 0 from 0 and we're left 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.

After the division, we end up with 33564.5 and a remainder of 0.0.
