We look at the division of 21212771 by 25 
We want to figure out the number of times 21212771 can be divided by 25.

On to step 1:
25 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 25

Moving on to step 2:
21 divided by 25 is 0 with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Include the next digit (2) from the dividend after 21, then repeat: 212 / 25

Going ahead to step 3:
25 can be fit into 212 8 times, resulting in a remainder of 12.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 200 from 212, we get 12.
Bring next digit (1) of the dividend behind the 12 and repeat the process: 121 / 25

Moving on to step 4:
When dividing 121 by 25, we get 4 with a remainder of 21.
Use 4 as the next digit of our solution. 
Result so far: 84.0
The remainder is 21 after subtracting 100 from 121.
Include the next digit (2) from the dividend after 21, then repeat: 212 / 25

On to step 5:
When dividing 212 by 25, we get 8 with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 848.0
The remainder is 12 after subtracting 200 from 212.
Fetch the next digit (7) from the dividend, attach it to 12 and continue: 127 / 25

Let's proceed to step 6:
127 divided by 25 is 5 with a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 8485.0
The remainder is 2 after subtracting 125 from 127.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 25

Advancing to step 7:
The number 25 fits into 27 1 times, leaving a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 84851.0
If we take 25 away from 27, we end up with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 25

Advancing to step 8:
25 goes into 21 0 times with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 848510.0
Subtract 0 from 21 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 9:
If we divide 210 by 25, we get 8 and a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 848510.8
Deduct 200 from 210 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
When dividing 100 by 25, we get 4 with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 848510.84
Subtract 100 from 100 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.

Going ahead to step 11:
25 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 848510.84
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.

Moving on to step 12:
0 divided by 25 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 848510.84
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.

In conclusion, the division gives 848510.84 with a balance of 0.0.
