Let's divide 16519 by 25
We want to divide 16519 by 25.

Advancing to step 1:
The number 25 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 25

Going ahead to step 2:
The number 25 fits into 16 0 times, leaving a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 16 after subtracting 0 from 16.
Grab the next digit (5) from the dividend, add it to 16, then carry on: 165 / 25

Step 3:
If we divide 165 by 25, we get 6 and a remainder of 15.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we subtract 150 from 165, we get 15.
Take the next digit (1) from the dividend and append it to 15, then repeat: 151 / 25

Step 4:
The number 25 fits into 151 6 times, leaving a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 66.0
The remainder is 1 after subtracting 150 from 151.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 25

Going ahead to step 5:
If we divide 19 by 25, we get 0 and a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 660.0
Subtract 0 from 19 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 6:
25 goes into 190 7 times with a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 660.7
Subtracting 175 from 190 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 7:
150 divided by 25 is 6 with a remainder of 0.
The next digit of our result is 6. 
Result so far: 660.76
Subtract 150 from 150 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 8:
25 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 660.76
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.

Step 9:
The number 25 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 660.76
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.

The final result is 660.76 with a remainder of 0.0.
