584497 ÷ 20 
We want to figure out the number of times 584497 can be divided by 20.

Step 1:
The number 20 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
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

On to step 2:
20 goes into 58 2 times with a remainder of 18.
The next digit of our result is 2. 
Result so far: 2.0
If we take 40 away from 58, we end up with 18.
Bring next digit (4) of the dividend behind the 18 and repeat the process: 184 / 20

On to step 3:
20 can be fit into 184 9 times, resulting in a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 29.0
Subtracting 180 from 184 leaves us with 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 20

Step 4:
When dividing 44 by 20, we get 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 292.0
Subtract 40 from 44 to get 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 20

Step 5:
20 goes into 49 2 times with a remainder of 9.
Record the quotient 2 as the next digit in the result. 
Result so far: 2922.0
Subtract 40 from 49 to get 9.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 20

Step 6:
97 divided by 20 is 4 with a remainder of 17.
Put 4 as the next digit of the answer. 
Result so far: 29224.0
If we subtract 80 from 97, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 7:
The number 20 fits into 170 8 times, leaving a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 29224.8
Deduct 160 from 170 and we're left 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.

Step 8:
When dividing 100 by 20, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 29224.85
Subtract 100 from 100 to 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.

Advancing to step 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 29224.85
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:
If we divide 0 by 20, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 29224.85
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.

After the division, we end up with 29224.85 and a remainder of 0.0.
