We look at the division of 621784 by 25 
We want to divide 621784 by 25.

Let's proceed to step 1:
The number 25 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 25

Going ahead to step 2:
25 goes into 62 2 times with a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 12 after subtracting 50 from 62.
Bring next digit (1) of the dividend behind the 12 and repeat the process: 121 / 25

Going ahead to step 3:
121 divided by 25 is 4 with a remainder of 21.
The next digit of our result is 4. 
Result so far: 24.0
Subtract 100 from 121 to get 21.
Fetch the next digit (7) from the dividend, attach it to 21 and continue: 217 / 25

Step 4:
When dividing 217 by 25, we get 8 with a remainder of 17.
The number 8 becomes the next digit in our result. 
Result so far: 248.0
Subtracting 200 from 217 leaves us with 17.
Fetch the next digit (8) from the dividend, attach it to 17 and continue: 178 / 25

Going ahead to step 5:
25 goes into 178 7 times with a remainder of 3.
The next digit of our result is 7. 
Result so far: 2487.0
The remainder is 3 after subtracting 175 from 178.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 25

Advancing to step 6:
34 divided by 25 is 1 with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 24871.0
Subtract 25 from 34 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 7:
The number 25 fits into 90 3 times, leaving a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 24871.3
Subtracting 75 from 90 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.

Advancing to step 8:
25 can be fit into 150 6 times, resulting in a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 24871.36
If we take 150 away from 150, 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:
25 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 24871.36
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.

On to step 10:
25 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 24871.36
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 24871.36, with a leftover of 0.0.
