We divide 839030 by 20
We're looking to find how many times 20 goes into 839030.

On to step 1:
If we divide 8 by 20, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 20

Moving on to step 2:
When dividing 83 by 20, we get 4 with a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 80 from 83 to get 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 20

Step 3:
39 divided by 20 is 1 with a remainder of 19.
The next digit of our result is 1. 
Result so far: 41.0
The remainder is 19 after subtracting 20 from 39.
Include the next digit (0) from the dividend after 19, then repeat: 190 / 20

Step 4:
If we divide 190 by 20, we get 9 and 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.
Include the next digit (3) from the dividend after 10, then repeat: 103 / 20

On to step 5:
20 goes into 103 5 times with a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 4195.0
If we subtract 100 from 103, we get 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 20

Let's proceed to step 6:
If we divide 30 by 20, we get 1 and a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 41951.0
The remainder is 10 after subtracting 20 from 30.
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 7:
20 goes into 100 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 41951.5
If we take 100 away from 100, 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.

Moving on to step 8:
0 divided by 20 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 41951.5
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.

Let's proceed to step 9:
0 divided by 20 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 41951.5
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.

Our division results in 41951.5 with a remaining 0.0.
