We divide 57087 by 20
Let's see how many times 20 fits into 57087.

On to step 1:
20 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 20

On to step 2:
20 goes into 57 2 times with a remainder of 17.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 17 after subtracting 40 from 57.
Fetch the next digit (0) from the dividend, attach it to 17 and continue: 170 / 20

On to step 3:
20 goes into 170 8 times with a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
Subtracting 160 from 170 leaves us with 10.
Fetch the next digit (8) from the dividend, attach it to 10 and continue: 108 / 20

Step 4:
If we divide 108 by 20, we get 5 and a remainder of 8.
Put 5 as the next digit of the answer. 
Result so far: 285.0
The remainder is 8 after subtracting 100 from 108.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 20

Let's proceed to step 5:
20 goes into 87 4 times with a remainder of 7.
Put 4 as the next digit of the answer. 
Result so far: 2854.0
Deduct 80 from 87 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 6:
The number 20 fits into 70 3 times, leaving a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 2854.3
Deduct 60 from 70 and we're left 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.

Let's proceed to step 7:
20 goes into 100 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 2854.35
If we subtract 100 from 100, 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 8:
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: 2854.35
Subtract 0 from 0 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.

Step 9:
20 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 2854.35
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 2854.35, and the remainder is 0.0.
