We look at the division of 816347 by 25 
We want to figure out the number of times 816347 can be divided by 25.

Advancing to step 1:
The number 25 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 25

Step 2:
25 goes into 81 3 times with a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 75 from 81 and we're left with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 25

On to step 3:
If we divide 66 by 25, we get 2 and a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 32.0
Deduct 50 from 66 and we're left with 16.
Grab the next digit (3) from the dividend, add it to 16, then carry on: 163 / 25

On to step 4:
The number 25 fits into 163 6 times, leaving a remainder of 13.
The next digit of our result is 6. 
Result so far: 326.0
Deduct 150 from 163 and we're left with 13.
Include the next digit (4) from the dividend after 13, then repeat: 134 / 25

Advancing to step 5:
25 goes into 134 5 times with a remainder of 9.
Put 5 as the next digit of the answer. 
Result so far: 3265.0
If we take 125 away from 134, we end up with 9.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 25

Going ahead to step 6:
If we divide 97 by 25, we get 3 and a remainder of 22.
The number 3 becomes the next digit in our result. 
Result so far: 32653.0
Subtract 75 from 97 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 7:
25 goes into 220 8 times with a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 32653.8
If we subtract 200 from 220, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
25 goes into 200 8 times with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 32653.88
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.

The quotient of the division is 32653.88, and the remainder is 0.0.
