We look at the division of 211221 by 25 
We want to divide 211221 by 25.

Let's proceed to step 1:
2 divided by 25 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 25

Step 2:
If we divide 21 by 25, we get 0 and a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Include the next digit (1) from the dividend after 21, then repeat: 211 / 25

Going ahead to step 3:
25 goes into 211 8 times with a remainder of 11.
The next digit of our result is 8. 
Result so far: 8.0
The remainder is 11 after subtracting 200 from 211.
Grab the next digit (2) from the dividend, add it to 11, then carry on: 112 / 25

On to step 4:
The number 25 fits into 112 4 times, leaving a remainder of 12.
The next digit of our result is 4. 
Result so far: 84.0
Subtracting 100 from 112 leaves us with 12.
Append the next digit (2) from the dividend to 12 and continue with: 122 / 25

On to step 5:
When dividing 122 by 25, we get 4 with a remainder of 22.
Record the quotient 4 as the next digit in the result. 
Result so far: 844.0
If we subtract 100 from 122, we get 22.
Include the next digit (1) from the dividend after 22, then repeat: 221 / 25

On to step 6:
The number 25 fits into 221 8 times, leaving a remainder of 21.
Record the quotient 8 as the next digit in the result. 
Result so far: 8448.0
Deduct 200 from 221 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:
When dividing 210 by 25, we get 8 with a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 8448.8
If we take 200 away from 210, we end up 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.

Going ahead to step 8:
When dividing 100 by 25, we get 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 8448.84
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.

On to step 9:
25 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 8448.84
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:
The number 25 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 8448.84
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 final outcome is 8448.84, with a leftover of 0.0.
