486653 ÷ 20 
We're looking to find how many times 20 goes into 486653.

Let's proceed to step 1:
When dividing 4 by 20, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 20

Advancing to step 2:
The number 20 fits into 48 2 times, leaving a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 40 from 48, we get 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 20

Advancing to step 3:
20 goes into 86 4 times with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
If we take 80 away from 86, we end up with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 20

Advancing to step 4:
20 can be fit into 66 3 times, resulting in a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 243.0
The remainder is 6 after subtracting 60 from 66.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 20

Advancing to step 5:
If we divide 65 by 20, we get 3 and a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 2433.0
Subtract 60 from 65 to get 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 20

Going ahead to step 6:
20 goes into 53 2 times with a remainder of 13.
Use 2 as the next digit of our solution. 
Result so far: 24332.0
Subtract 40 from 53 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 7:
When dividing 130 by 20, we get 6 with a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 24332.6
Subtract 120 from 130 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.

Let's proceed to step 8:
100 divided by 20 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 24332.65
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.

Moving on to step 9:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 24332.65
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.

Step 10:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 24332.65
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.

The final outcome is 24332.65, with a leftover of 0.0.
