We're dividing 587999 by 20 
We're looking to find how many times 20 goes into 587999.

Advancing to step 1:
If we divide 5 by 20, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 20

Moving on to step 2:
20 can be fit into 58 2 times, resulting in a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 40 from 58 and we're left with 18.
Bring next digit (7) of the dividend behind the 18 and repeat the process: 187 / 20

Let's proceed to step 3:
20 goes into 187 9 times with a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 29.0
If we subtract 180 from 187, we get 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 20

Moving on to step 4:
20 goes into 79 3 times with a remainder of 19.
Write down 3 as next digit of the result. 
Result so far: 293.0
Deduct 60 from 79 and we're left with 19.
Include the next digit (9) from the dividend after 19, then repeat: 199 / 20

Going ahead to step 5:
20 can be fit into 199 9 times, resulting in a remainder of 19.
Write down 9 as next digit of the result. 
Result so far: 2939.0
If we take 180 away from 199, we end up with 19.
Fetch the next digit (9) from the dividend, attach it to 19 and continue: 199 / 20

Moving on to step 6:
20 goes into 199 9 times with a remainder of 19.
Use 9 as the next digit of our solution. 
Result so far: 29399.0
The remainder is 19 after subtracting 180 from 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 7:
If we divide 190 by 20, we get 9 and a remainder of 10.
Record the quotient 9 as the next digit in the result. 
Result so far: 29399.9
The remainder is 10 after subtracting 180 from 190.
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: 29399.95
Deduct 100 from 100 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.

On to step 9:
0 divided by 20 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 29399.95
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.

On to step 10:
20 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 29399.95
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.

Our division results in 29399.95 with a remaining 0.0.
