24604971 ÷ 20 
Our goal is to divide 24604971 by 20.

On to step 1:
The number 20 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 20

Moving on to step 2:
When dividing 24 by 20, we get 1 with a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 20 from 24 and we're left with 4.
Bring next digit (6) of the dividend behind the 4 and repeat the process: 46 / 20

Going ahead to step 3:
If we divide 46 by 20, we get 2 and a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Deduct 40 from 46 and we're left with 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 20

Let's proceed to step 4:
The number 20 fits into 60 3 times, leaving a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 123.0
Subtracting 60 from 60 leaves us with 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 20

Step 5:
If we divide 4 by 20, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 1230.0
If we subtract 0 from 4, we get 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 20

Advancing to step 6:
20 can be fit into 49 2 times, resulting in a remainder of 9.
Write down 2 as next digit of the result. 
Result so far: 12302.0
The remainder is 9 after subtracting 40 from 49.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 20

Step 7:
The number 20 fits into 97 4 times, leaving a remainder of 17.
The number 4 becomes the next digit in our result. 
Result so far: 123024.0
The remainder is 17 after subtracting 80 from 97.
Grab the next digit (1) from the dividend, add it to 17, then carry on: 171 / 20

Moving on to step 8:
The number 20 fits into 171 8 times, leaving a remainder of 11.
Write down 8 as next digit of the result. 
Result so far: 1230248.0
Deduct 160 from 171 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 9:
110 divided by 20 is 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 1230248.5
Subtract 100 from 110 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.

On to step 10:
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: 1230248.55
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.

After the division, we end up with 1230248.55 and a remainder of 0.0.
