488157 ÷ 20 
Our goal is to divide 488157 by 20.

Going ahead to step 1:
20 can be fit into 4 0 times, resulting in 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.
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.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 40 away from 48, we end up with 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 20

Moving on to step 3:
If we divide 88 by 20, we get 4 and a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 24.0
The remainder is 8 after subtracting 80 from 88.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 20

On to step 4:
The number 20 fits into 81 4 times, leaving a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 244.0
Deduct 80 from 81 and we're left with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 20

On to step 5:
20 can be fit into 15 0 times, resulting in a remainder of 15.
The next digit of our result is 0. 
Result so far: 2440.0
Subtracting 0 from 15 leaves us with 15.
Append the next digit (7) from the dividend to 15 and continue with: 157 / 20

Moving on to step 6:
If we divide 157 by 20, we get 7 and a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 24407.0
Deduct 140 from 157 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 7:
If we divide 170 by 20, we get 8 and a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 24407.8
If we subtract 160 from 170, 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.

Let's proceed 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: 24407.85
Subtracting 100 from 100 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 9:
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: 24407.85
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.

Moving on to step 10:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 24407.85
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 quotient of the division is 24407.85, and the remainder is 0.0.
