We're dividing 25720177 by 20 
Our goal is to divide 25720177 by 20.

Advancing to step 1:
20 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 20

Going ahead to step 2:
If we divide 25 by 20, we get 1 and a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 5 after subtracting 20 from 25.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 20

On to step 3:
The number 20 fits into 57 2 times, leaving a remainder of 17.
The next digit of our result is 2. 
Result so far: 12.0
Subtracting 40 from 57 leaves us with 17.
Grab the next digit (2) from the dividend, add it to 17, then carry on: 172 / 20

Let's proceed to step 4:
If we divide 172 by 20, we get 8 and a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 128.0
If we take 160 away from 172, we end up with 12.
Take the next digit (0) from the dividend and append it to 12, then repeat: 120 / 20

Moving on to step 5:
120 divided by 20 is 6 with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 1286.0
Subtracting 120 from 120 leaves us with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 20

Step 6:
The number 20 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 12860.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 20

Step 7:
20 goes into 17 0 times with a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 128600.0
Subtracting 0 from 17 leaves us with 17.
Bring next digit (7) of the dividend behind the 17 and repeat the process: 177 / 20

Moving on to step 8:
The number 20 fits into 177 8 times, leaving a remainder of 17.
Put 8 as the next digit of the answer. 
Result so far: 1286008.0
Deduct 160 from 177 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 9:
When dividing 170 by 20, we get 8 with a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 1286008.8
If we subtract 160 from 170, we 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.

Step 10:
100 divided by 20 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 1286008.85
Subtract 100 from 100 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 11:
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: 1286008.85
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.

Moving on to step 12:
0 divided by 20 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1286008.85
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.

After the division, we end up with 1286008.85 and a remainder of 0.0.
