We divide 257785 by 20
Let's see how many times 20 fits into 257785.

Moving on to step 1:
20 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 20

On to step 2:
25 divided by 20 is 1 with a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 20 from 25 leaves us with 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 20

Moving on to step 3:
20 goes into 57 2 times with a remainder of 17.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtracting 40 from 57 leaves us with 17.
Fetch the next digit (7) from the dividend, attach it to 17 and continue: 177 / 20

On to step 4:
177 divided by 20 is 8 with a remainder of 17.
Record the quotient 8 as the next digit in the result. 
Result so far: 128.0
Subtract 160 from 177 to get 17.
Append the next digit (8) from the dividend to 17 and continue with: 178 / 20

Let's proceed to step 5:
If we divide 178 by 20, we get 8 and a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 1288.0
Subtracting 160 from 178 leaves us with 18.
Bring next digit (5) of the dividend behind the 18 and repeat the process: 185 / 20

Let's proceed to step 6:
20 goes into 185 9 times with a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 12889.0
If we take 180 away from 185, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
If we divide 50 by 20, we get 2 and a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 12889.2
The remainder is 10 after subtracting 40 from 50.
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 8:
20 can be fit into 100 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 12889.25
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.

On to step 9:
When dividing 0 by 20, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 12889.25
Subtracting 0 from 0 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.

Step 10:
20 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 12889.25
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.

The final outcome is 12889.25, with a leftover of 0.0.
