We look at the division of 819042 by 25 
We're looking to find how many times 25 goes into 819042.

On 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
Deduct 0 from 8 and we're left with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 25

On to step 2:
The number 25 fits into 81 3 times, leaving a remainder of 6.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 6 after subtracting 75 from 81.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 25

Advancing to step 3:
The number 25 fits into 69 2 times, leaving a remainder of 19.
Put 2 as the next digit of the answer. 
Result so far: 32.0
The remainder is 19 after subtracting 50 from 69.
Include the next digit (0) from the dividend after 19, then repeat: 190 / 25

Step 4:
The number 25 fits into 190 7 times, leaving a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 327.0
Deduct 175 from 190 and we're left with 15.
Take the next digit (4) from the dividend and append it to 15, then repeat: 154 / 25

Step 5:
25 can be fit into 154 6 times, resulting in a remainder of 4.
The next digit of our result is 6. 
Result so far: 3276.0
If we subtract 150 from 154, we get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 25

Moving on to step 6:
When dividing 42 by 25, we get 1 with a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 32761.0
Subtract 25 from 42 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 7:
The number 25 fits into 170 6 times, leaving a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 32761.6
Subtracting 150 from 170 leaves us with 20.
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 8:
200 divided by 25 is 8 with a remainder of 0.
The next digit of our result is 8. 
Result so far: 32761.68
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.

Going ahead to step 9:
25 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 32761.68
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.

Advancing to step 10:
If we divide 0 by 25, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 32761.68
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.

Our division results in 32761.68 with a remaining 0.0.
