Let's divide 212497 by 25
We want to figure out the number of times 212497 can be divided by 25.

Step 1:
2 divided by 25 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 25

Advancing to step 2:
25 goes into 21 0 times with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Take the next digit (2) from the dividend and append it to 21, then repeat: 212 / 25

Advancing to step 3:
The number 25 fits into 212 8 times, leaving a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we take 200 away from 212, we end up with 12.
Take the next digit (4) from the dividend and append it to 12, then repeat: 124 / 25

Step 4:
25 goes into 124 4 times with a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 84.0
If we subtract 100 from 124, we get 24.
Take the next digit (9) from the dividend and append it to 24, then repeat: 249 / 25

Going ahead to step 5:
When dividing 249 by 25, we get 9 with a remainder of 24.
Record the quotient 9 as the next digit in the result. 
Result so far: 849.0
The remainder is 24 after subtracting 225 from 249.
Append the next digit (7) from the dividend to 24 and continue with: 247 / 25

On to step 6:
If we divide 247 by 25, we get 9 and a remainder of 22.
The next digit of our result is 9. 
Result so far: 8499.0
Subtracting 225 from 247 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 7:
When dividing 220 by 25, we get 8 with a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 8499.8
Deduct 200 from 220 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.

Let's proceed to step 8:
25 goes into 200 8 times with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 8499.88
Subtract 200 from 200 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.

The final result is 8499.88 with a remainder of 0.0.
