848020 ÷ 20 
Our goal is to divide 848020 by 20.

On to step 1:
8 divided by 20 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 20

Advancing to step 2:
If we divide 84 by 20, we get 4 and a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 80 away from 84, we end up with 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 20

Advancing to step 3:
20 goes into 48 2 times with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 42.0
The remainder is 8 after subtracting 40 from 48.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 20

On to step 4:
When dividing 80 by 20, we get 4 with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 424.0
Deduct 80 from 80 and we're left with 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 20

Going ahead to step 5:
If we divide 2 by 20, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 4240.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 20

Step 6:
20 divided by 20 is 1 with a remainder of 0.
The next digit of our result is 1. 
Result so far: 42401.0
Deduct 20 from 20 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.

Moving on to step 7:
20 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 42401.0
If we subtract 0 from 0, we 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.

Going ahead to step 8:
0 divided by 20 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 42401.0
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.

After the division, we end up with 42401.0 and a remainder of 0.0.
