We're dividing 839053 by 20 
Let's see how many times 20 fits into 839053.

Advancing to step 1:
8 divided by 20 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 20

Let's proceed to step 2:
If we divide 83 by 20, we get 4 and a remainder of 3.
The next digit of our result is 4. 
Result so far: 4.0
If we take 80 away from 83, we end up with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 20

Going ahead to step 3:
39 divided by 20 is 1 with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 41.0
Deduct 20 from 39 and we're left with 19.
Bring next digit (0) of the dividend behind the 19 and repeat the process: 190 / 20

Step 4:
20 can be fit into 190 9 times, resulting in a remainder of 10.
Write down 9 as next digit of the result. 
Result so far: 419.0
If we take 180 away from 190, we end up with 10.
Bring next digit (5) of the dividend behind the 10 and repeat the process: 105 / 20

Moving on to step 5:
The number 20 fits into 105 5 times, leaving a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 4195.0
If we subtract 100 from 105, we get 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 20

Step 6:
20 can be fit into 53 2 times, resulting in a remainder of 13.
Put 2 as the next digit of the answer. 
Result so far: 41952.0
Subtract 40 from 53 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 7:
130 divided by 20 is 6 with a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 41952.6
The remainder is 10 after subtracting 120 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
100 divided by 20 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 41952.65
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 9:
20 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 41952.65
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.

Let's proceed to step 10:
0 divided by 20 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 41952.65
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.

Our division results in 41952.65 with a remaining 0.0.
