We look at the division of 24859401 by 20 
We're looking to find how many times 20 goes into 24859401.

Let's proceed to step 1:
If we divide 2 by 20, we get 0 and 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.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 20

Step 2:
The number 20 fits into 24 1 times, leaving a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 4 after subtracting 20 from 24.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 20

Going ahead to step 3:
If we divide 48 by 20, we get 2 and a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtracting 40 from 48 leaves us with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 20

Going ahead to step 4:
When dividing 85 by 20, we get 4 with a remainder of 5.
Put 4 as the next digit of the answer. 
Result so far: 124.0
Subtract 80 from 85 to get 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 20

On to step 5:
The number 20 fits into 59 2 times, leaving a remainder of 19.
Use 2 as the next digit of our solution. 
Result so far: 1242.0
If we subtract 40 from 59, we get 19.
Grab the next digit (4) from the dividend, add it to 19, then carry on: 194 / 20

Advancing to step 6:
If we divide 194 by 20, we get 9 and a remainder of 14.
The next digit of our result is 9. 
Result so far: 12429.0
The remainder is 14 after subtracting 180 from 194.
Grab the next digit (0) from the dividend, add it to 14, then carry on: 140 / 20

Going ahead to step 7:
The number 20 fits into 140 7 times, leaving a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 124297.0
Subtracting 140 from 140 leaves us with 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 20

Let's proceed to step 8:
If we divide 1 by 20, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 1242970.0
Subtract 0 from 1 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 9:
10 divided by 20 is 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 1242970.0
If we take 0 away from 10, we end up 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.

Advancing to step 10:
When dividing 100 by 20, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 1242970.05
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 11:
If we divide 0 by 20, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1242970.05
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.

Advancing to step 12:
20 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 1242970.05
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.

The quotient of the division is 1242970.05, and the remainder is 0.0.
