803147 ÷ 25 
We're looking to find how many times 25 goes into 803147.

Step 1:
25 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 25

Going ahead to step 2:
If we divide 80 by 25, we get 3 and a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 75 from 80 and we're left with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 25

Going ahead to step 3:
25 can be fit into 53 2 times, resulting in a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 32.0
Deduct 50 from 53 and we're left with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 25

On to step 4:
25 goes into 31 1 times with a remainder of 6.
The next digit of our result is 1. 
Result so far: 321.0
If we subtract 25 from 31, we get 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 25

Moving on to step 5:
The number 25 fits into 64 2 times, leaving a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 3212.0
If we take 50 away from 64, we end up with 14.
Take the next digit (7) from the dividend and append it to 14, then repeat: 147 / 25

Let's proceed to step 6:
The number 25 fits into 147 5 times, leaving a remainder of 22.
Record the quotient 5 as the next digit in the result. 
Result so far: 32125.0
If we subtract 125 from 147, we 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.

Step 7:
25 goes into 220 8 times with a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 32125.8
The remainder is 20 after subtracting 200 from 220.
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:
The number 25 fits into 200 8 times, leaving a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 32125.88
If we take 200 away from 200, 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.

The quotient of the division is 32125.88, and the remainder is 0.0.
