We look at the division of 790521 by 25 
We want to figure out the number of times 790521 can be divided by 25.

Moving on to step 1:
If we divide 7 by 25, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 25

On to step 2:
25 can be fit into 79 3 times, resulting in a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 75 away from 79, we end up with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 25

Step 3:
25 goes into 40 1 times with a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 31.0
Subtracting 25 from 40 leaves us with 15.
Bring next digit (5) of the dividend behind the 15 and repeat the process: 155 / 25

On to step 4:
The number 25 fits into 155 6 times, leaving a remainder of 5.
Use 6 as the next digit of our solution. 
Result so far: 316.0
Subtract 150 from 155 to get 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 25

Step 5:
When dividing 52 by 25, we get 2 with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 3162.0
Deduct 50 from 52 and we're left with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 25

Let's proceed to step 6:
21 divided by 25 is 0 with a remainder of 21.
The next digit of our result is 0. 
Result so far: 31620.0
Deduct 0 from 21 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 7:
25 goes into 210 8 times with a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 31620.8
Subtract 200 from 210 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
The number 25 fits into 100 4 times, leaving a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 31620.84
Subtracting 100 from 100 leaves us 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 9:
25 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 31620.84
The remainder is 0 after subtracting 0 from 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.
Put 0 as the next digit of the answer. 
Result so far: 31620.84
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.

The quotient of the division is 31620.84, and the remainder is 0.0.
