We look at the division of 80721800 by 25 
We want to figure out the number of times 80721800 can be divided by 25.

Moving on to step 1:
The number 25 fits into 8 0 times, leaving 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 (0) of the dividend behind the 8 and repeat the process: 80 / 25

On to step 2:
25 goes into 80 3 times with a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 75 from 80, we get 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 25

Let's proceed to step 3:
25 can be fit into 57 2 times, resulting in a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 32.0
Subtract 50 from 57 to get 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 25

Advancing to step 4:
25 goes into 72 2 times with a remainder of 22.
The next digit of our result is 2. 
Result so far: 322.0
The remainder is 22 after subtracting 50 from 72.
Grab the next digit (1) from the dividend, add it to 22, then carry on: 221 / 25

Step 5:
When dividing 221 by 25, we get 8 with a remainder of 21.
The next digit of our result is 8. 
Result so far: 3228.0
If we take 200 away from 221, we end up with 21.
Bring next digit (8) of the dividend behind the 21 and repeat the process: 218 / 25

Let's proceed to step 6:
When dividing 218 by 25, we get 8 with a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 32288.0
Subtract 200 from 218 to get 18.
Bring next digit (0) of the dividend behind the 18 and repeat the process: 180 / 25

Going ahead to step 7:
The number 25 fits into 180 7 times, leaving a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 322887.0
Subtracting 175 from 180 leaves us with 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 25

Step 8:
When dividing 50 by 25, we get 2 with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 3228872.0
Subtract 50 from 50 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.

Step 9:
When dividing 0 by 25, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 3228872.0
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.

Moving on to step 10:
25 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 3228872.0
Deduct 0 from 0 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 3228872.0, and the remainder is 0.0.
