We look at the division of 525978 by 25 
We want to divide 525978 by 25.

Moving on to step 1:
The number 25 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 25

On to step 2:
The number 25 fits into 52 2 times, leaving a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 50 from 52 and we're left with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 25

Going ahead to step 3:
When dividing 25 by 25, we get 1 with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
Deduct 25 from 25 and we're left with 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 25

Advancing to step 4:
When dividing 9 by 25, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 210.0
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 25

Let's proceed to step 5:
When dividing 97 by 25, we get 3 with a remainder of 22.
The next digit of our result is 3. 
Result so far: 2103.0
The remainder is 22 after subtracting 75 from 97.
Bring next digit (8) of the dividend behind the 22 and repeat the process: 228 / 25

Step 6:
25 can be fit into 228 9 times, resulting in a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 21039.0
Deduct 225 from 228 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
25 can be fit into 30 1 times, resulting in a remainder of 5.
The next digit of our result is 1. 
Result so far: 21039.1
The remainder is 5 after subtracting 25 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 8:
25 goes into 50 2 times with a remainder of 0.
The next digit of our result is 2. 
Result so far: 21039.12
If we subtract 50 from 50, 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.

Step 9:
If we divide 0 by 25, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 21039.12
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 10:
If we divide 0 by 25, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 21039.12
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 outcome is 21039.12, with a leftover of 0.0.
