72504890 ÷ 25 
We want to figure out the number of times 72504890 can be divided by 25.

Let's proceed to step 1:
When dividing 7 by 25, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 25

Going ahead to step 2:
If we divide 72 by 25, we get 2 and a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 50 from 72 to get 22.
Include the next digit (5) from the dividend after 22, then repeat: 225 / 25

On to step 3:
When dividing 225 by 25, we get 9 with a remainder of 0.
The next digit of our result is 9. 
Result so far: 29.0
Subtract 225 from 225 to get 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 25

Moving on to step 4:
0 divided by 25 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 290.0
Subtract 0 from 0 to get 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 25

Advancing to step 5:
25 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 2900.0
If we take 0 away from 4, we end up with 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 25

On to step 6:
If we divide 48 by 25, we get 1 and a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 29001.0
If we subtract 25 from 48, we get 23.
Include the next digit (9) from the dividend after 23, then repeat: 239 / 25

Advancing to step 7:
25 can be fit into 239 9 times, resulting in a remainder of 14.
Use 9 as the next digit of our solution. 
Result so far: 290019.0
If we subtract 225 from 239, we get 14.
Grab the next digit (0) from the dividend, add it to 14, then carry on: 140 / 25

Let's proceed to step 8:
25 goes into 140 5 times with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 2900195.0
If we take 125 away from 140, we end up 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.

Going ahead to step 9:
When dividing 150 by 25, we get 6 with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 2900195.6
If we subtract 150 from 150, we 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.

Going ahead to step 10:
When dividing 0 by 25, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 2900195.6
If we subtract 0 from 0, we 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.

Advancing to step 11:
25 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 2900195.6
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 final result is 2900195.6 with a remainder of 0.0.
