804129 ÷ 25 
We want to figure out the number of times 804129 can be divided by 25.

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
Subtract 0 from 8 to get 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 25

Going ahead to step 2:
If we divide 80 by 25, we get 3 and a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 75 from 80 and we're left with 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 25

Moving on to step 3:
54 divided by 25 is 2 with a remainder of 4.
The next digit of our result is 2. 
Result so far: 32.0
Deduct 50 from 54 and we're left with 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 25

Moving on to step 4:
25 can be fit into 41 1 times, resulting in a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 321.0
Subtract 25 from 41 to get 16.
Fetch the next digit (2) from the dividend, attach it to 16 and continue: 162 / 25

Moving on to step 5:
If we divide 162 by 25, we get 6 and a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 3216.0
The remainder is 12 after subtracting 150 from 162.
Take the next digit (9) from the dividend and append it to 12, then repeat: 129 / 25

Advancing to step 6:
129 divided by 25 is 5 with a remainder of 4.
The next digit of our result is 5. 
Result so far: 32165.0
Subtracting 125 from 129 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
25 can be fit into 40 1 times, resulting in a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 32165.1
Deduct 25 from 40 and we're left 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.

Moving on to step 8:
25 goes into 150 6 times with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 32165.16
Deduct 150 from 150 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.

Moving on to step 9:
25 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 32165.16
If we take 0 away from 0, 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.

Going ahead to step 10:
The number 25 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 32165.16
Subtract 0 from 0 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.

The final result is 32165.16 with a remainder of 0.0.
