We look at the division of 511170 by 25 
Our goal is to divide 511170 by 25.

Moving on to step 1:
The number 25 fits into 5 0 times, leaving 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.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 25

Going ahead to step 2:
The number 25 fits into 51 2 times, leaving a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 50 away from 51, we end up with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 25

Step 3:
The number 25 fits into 11 0 times, leaving a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 20.0
Subtracting 0 from 11 leaves us with 11.
Include the next digit (1) from the dividend after 11, then repeat: 111 / 25

Going ahead to step 4:
If we divide 111 by 25, we get 4 and a remainder of 11.
Record the quotient 4 as the next digit in the result. 
Result so far: 204.0
Deduct 100 from 111 and we're left with 11.
Include the next digit (7) from the dividend after 11, then repeat: 117 / 25

Advancing to step 5:
117 divided by 25 is 4 with a remainder of 17.
The next digit of our result is 4. 
Result so far: 2044.0
If we take 100 away from 117, we end up with 17.
Fetch the next digit (0) from the dividend, attach it to 17 and continue: 170 / 25

Advancing to step 6:
170 divided by 25 is 6 with a remainder of 20.
The next digit of our result is 6. 
Result so far: 20446.0
The remainder is 20 after subtracting 150 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 7:
200 divided by 25 is 8 with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 20446.8
Deduct 200 from 200 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.

On to step 8:
The number 25 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 20446.8
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.

Going ahead to step 9:
0 divided by 25 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 20446.8
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 20446.8, with a leftover of 0.0.
