212790 ÷ 25 
We want to divide 212790 by 25.

Let's proceed to step 1:
25 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 25

Let's proceed to step 2:
25 can be fit into 21 0 times, resulting in 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 (2) from the dividend after 21, then repeat: 212 / 25

Going ahead to step 3:
The number 25 fits into 212 8 times, leaving a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 200 from 212 and we're left with 12.
Include the next digit (7) from the dividend after 12, then repeat: 127 / 25

Let's proceed to step 4:
25 goes into 127 5 times with a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 85.0
The remainder is 2 after subtracting 125 from 127.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 25

Going ahead to step 5:
The number 25 fits into 29 1 times, leaving a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 851.0
If we take 25 away from 29, we end up with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 25

Going ahead to step 6:
If we divide 40 by 25, we get 1 and a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 8511.0
If we subtract 25 from 40, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 7:
150 divided by 25 is 6 with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 8511.6
Deduct 150 from 150 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.

Step 8:
0 divided by 25 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 8511.6
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.

Let's proceed to step 9:
0 divided by 25 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 8511.6
Subtract 0 from 0 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.

Our division results in 8511.6 with a remaining 0.0.
