We're dividing 959646 by 20 
We want to divide 959646 by 20.

On to step 1:
The number 20 fits into 9 0 times, leaving a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Append the next digit (5) from the dividend to 9 and continue with: 95 / 20

Let's proceed to step 2:
The number 20 fits into 95 4 times, leaving a remainder of 15.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 80 from 95, we get 15.
Take the next digit (9) from the dividend and append it to 15, then repeat: 159 / 20

Let's proceed to step 3:
20 goes into 159 7 times with a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 47.0
The remainder is 19 after subtracting 140 from 159.
Fetch the next digit (6) from the dividend, attach it to 19 and continue: 196 / 20

Step 4:
196 divided by 20 is 9 with a remainder of 16.
Put 9 as the next digit of the answer. 
Result so far: 479.0
Subtract 180 from 196 to get 16.
Include the next digit (4) from the dividend after 16, then repeat: 164 / 20

Going ahead to step 5:
164 divided by 20 is 8 with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 4798.0
Deduct 160 from 164 and we're left with 4.
Bring next digit (6) of the dividend behind the 4 and repeat the process: 46 / 20

Moving on to step 6:
The number 20 fits into 46 2 times, leaving a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 47982.0
If we take 40 away from 46, we end up 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.

On to step 7:
60 divided by 20 is 3 with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 47982.3
If we take 60 away from 60, 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.

On to step 8:
If we divide 0 by 20, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 47982.3
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.

Advancing to step 9:
When dividing 0 by 20, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 47982.3
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.

After the division, we end up with 47982.3 and a remainder of 0.0.
