586465 ÷ 20 
We're looking to find how many times 20 goes into 586465.

Advancing to step 1:
The number 20 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 20

Step 2:
When dividing 58 by 20, we get 2 with a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 40 away from 58, we end up with 18.
Include the next digit (6) from the dividend after 18, then repeat: 186 / 20

Advancing to step 3:
186 divided by 20 is 9 with a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
Subtracting 180 from 186 leaves us with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 20

Going ahead to step 4:
If we divide 64 by 20, we get 3 and a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 293.0
The remainder is 4 after subtracting 60 from 64.
Bring next digit (6) of the dividend behind the 4 and repeat the process: 46 / 20

Advancing to step 5:
20 can be fit into 46 2 times, resulting in a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 2932.0
Subtract 40 from 46 to get 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 20

On to step 6:
When dividing 65 by 20, we get 3 with a remainder of 5.
The next digit of our result is 3. 
Result so far: 29323.0
If we take 60 away from 65, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 7:
The number 20 fits into 50 2 times, leaving a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 29323.2
If we take 40 away from 50, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
20 goes into 100 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 29323.25
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.

Moving on to step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 29323.25
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.

Advancing to step 10:
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: 29323.25
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.

In conclusion, the division gives 29323.25 with a balance of 0.0.
