Let's divide 858286 by 25
We want to divide 858286 by 25.

Going ahead to step 1:
If we divide 8 by 25, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 25

Advancing to step 2:
When dividing 85 by 25, we get 3 with a remainder of 10.
The next digit of our result is 3. 
Result so far: 3.0
If we take 75 away from 85, we end up with 10.
Fetch the next digit (8) from the dividend, attach it to 10 and continue: 108 / 25

Going ahead to step 3:
The number 25 fits into 108 4 times, leaving a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 34.0
If we subtract 100 from 108, we get 8.
Include the next digit (2) from the dividend after 8, then repeat: 82 / 25

Going ahead to step 4:
25 goes into 82 3 times with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 343.0
If we subtract 75 from 82, we get 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 25

On to step 5:
When dividing 78 by 25, we get 3 with a remainder of 3.
The next digit of our result is 3. 
Result so far: 3433.0
If we subtract 75 from 78, we get 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 25

On to step 6:
The number 25 fits into 36 1 times, leaving a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 34331.0
If we subtract 25 from 36, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 7:
The number 25 fits into 110 4 times, leaving a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 34331.4
If we take 100 away from 110, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
When dividing 100 by 25, we get 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 34331.44
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.

After the division, we end up with 34331.44 and a remainder of 0.0.
