We're dividing 586803 by 20 
We want to divide 586803 by 20.

Going ahead to step 1:
20 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 20

Let's proceed to step 2:
58 divided by 20 is 2 with a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 40 from 58, we get 18.
Append the next digit (6) from the dividend to 18 and continue with: 186 / 20

Moving on to step 3:
186 divided by 20 is 9 with a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 29.0
The remainder is 6 after subtracting 180 from 186.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 20

Let's proceed to step 4:
68 divided by 20 is 3 with a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 293.0
Subtract 60 from 68 to get 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 20

Moving on to step 5:
When dividing 80 by 20, we get 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 2934.0
If we subtract 80 from 80, we get 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 20

Going ahead to step 6:
If we divide 3 by 20, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 29340.0
Subtract 0 from 3 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
30 divided by 20 is 1 with a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 29340.1
Subtract 20 from 30 to get 10.
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:
When dividing 100 by 20, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 29340.15
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.

Going ahead to step 9:
When dividing 0 by 20, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 29340.15
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.

Advancing to step 10:
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: 29340.15
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.

After the division, we end up with 29340.15 and a remainder of 0.0.
