We look at the division of 977570 by 25 
Let's see how many times 25 fits into 977570.

Going ahead to step 1:
If we divide 9 by 25, we get 0 and a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 25

Moving on to step 2:
If we divide 97 by 25, we get 3 and a remainder of 22.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 75 from 97 and we're left with 22.
Take the next digit (7) from the dividend and append it to 22, then repeat: 227 / 25

Let's proceed to step 3:
If we divide 227 by 25, we get 9 and a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 39.0
The remainder is 2 after subtracting 225 from 227.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 25

On to step 4:
25 divided by 25 is 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 391.0
Subtract 25 from 25 to get 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 25

On to step 5:
7 divided by 25 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 3910.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 25

Step 6:
25 can be fit into 70 2 times, resulting in a remainder of 20.
The next digit of our result is 2. 
Result so far: 39102.0
Deduct 50 from 70 and we're left with 20.
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 7:
When dividing 200 by 25, we get 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 39102.8
If we subtract 200 from 200, 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 8:
0 divided by 25 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 39102.8
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.

Going ahead to step 9:
25 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 39102.8
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.

The final result is 39102.8 with a remainder of 0.0.
