We're dividing 486667 by 20 
Let's see how many times 20 fits into 486667.

On to step 1:
4 divided by 20 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 20

Let's proceed to step 2:
20 can be fit into 48 2 times, resulting in a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 40 from 48 leaves us with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 20

On to step 3:
86 divided by 20 is 4 with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
If we take 80 away from 86, we end up with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 20

Going ahead to step 4:
If we divide 66 by 20, we get 3 and a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 243.0
Subtracting 60 from 66 leaves us with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 20

Let's proceed to step 5:
The number 20 fits into 66 3 times, leaving a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 2433.0
Deduct 60 from 66 and we're left with 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 20

Going ahead to step 6:
The number 20 fits into 67 3 times, leaving a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 24333.0
Deduct 60 from 67 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 7:
20 can be fit into 70 3 times, resulting in a remainder of 10.
The next digit of our result is 3. 
Result so far: 24333.3
If we subtract 60 from 70, we 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.

Step 8:
100 divided by 20 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 24333.35
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.

Moving on to step 9:
0 divided by 20 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 24333.35
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.

Let's proceed to step 10:
If we divide 0 by 20, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 24333.35
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.

The final outcome is 24333.35, with a leftover of 0.0.
