Let's divide 960840 by 20
We're looking to find how many times 20 goes into 960840.

Advancing to step 1:
When dividing 9 by 20, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (6) from the dividend to 9 and continue with: 96 / 20

Step 2:
96 divided by 20 is 4 with a remainder of 16.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 16 after subtracting 80 from 96.
Bring next digit (0) of the dividend behind the 16 and repeat the process: 160 / 20

Going ahead to step 3:
The number 20 fits into 160 8 times, leaving a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 48.0
Deduct 160 from 160 and we're left with 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 20

Advancing to step 4:
20 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 480.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 20

On to step 5:
20 goes into 84 4 times with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 4804.0
If we take 80 away from 84, we end up with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 20

Let's proceed to step 6:
If we divide 40 by 20, we get 2 and a remainder of 0.
The next digit of our result is 2. 
Result so far: 48042.0
Subtract 40 from 40 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.

Let's proceed to step 7:
0 divided by 20 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 48042.0
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.

On to step 8:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 48042.0
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.

After the division, we end up with 48042.0 and a remainder of 0.0.
