64875081 divided by 20 
Our goal is to divide 64875081 by 20.

Going ahead to step 1:
If we divide 6 by 20, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 20

Going ahead to step 2:
The number 20 fits into 64 3 times, leaving a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 60 away from 64, we end up with 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 20

On to step 3:
When dividing 48 by 20, we get 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 32.0
Subtracting 40 from 48 leaves us with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 20

On to step 4:
The number 20 fits into 87 4 times, leaving a remainder of 7.
The number 4 becomes the next digit in our result. 
Result so far: 324.0
Subtracting 80 from 87 leaves us with 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 20

Let's proceed to step 5:
When dividing 75 by 20, we get 3 with a remainder of 15.
The next digit of our result is 3. 
Result so far: 3243.0
Subtract 60 from 75 to get 15.
Append the next digit (0) from the dividend to 15 and continue with: 150 / 20

Moving on to step 6:
If we divide 150 by 20, we get 7 and a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 32437.0
Deduct 140 from 150 and we're left with 10.
Fetch the next digit (8) from the dividend, attach it to 10 and continue: 108 / 20

Going ahead to step 7:
When dividing 108 by 20, we get 5 with a remainder of 8.
The number 5 becomes the next digit in our result. 
Result so far: 324375.0
Subtracting 100 from 108 leaves us with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 20

Going ahead to step 8:
20 can be fit into 81 4 times, resulting in a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 3243754.0
The remainder is 1 after subtracting 80 from 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 9:
If we divide 10 by 20, we get 0 and a remainder of 10.
The next digit of our result is 0. 
Result so far: 3243754.0
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.

Going ahead to step 10:
If we divide 100 by 20, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 3243754.05
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.

Advancing to step 11:
The number 20 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 3243754.05
If we subtract 0 from 0, we 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.

Let's proceed to step 12:
20 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 3243754.05
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.

The quotient of the division is 3243754.05, and the remainder is 0.0.
