We look at the division of 256170 by 99 
We want to figure out the number of times 256170 can be divided by 99.

On to step 1:
The number 99 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 99

Moving on to step 2:
99 goes into 25 0 times with a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Take the next digit (6) from the dividend and append it to 25, then repeat: 256 / 99

On to step 3:
99 can be fit into 256 2 times, resulting in a remainder of 58.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 198 away from 256, we end up with 58.
Bring next digit (1) of the dividend behind the 58 and repeat the process: 581 / 99

Step 4:
99 can be fit into 581 5 times, resulting in a remainder of 86.
Use 5 as the next digit of our solution. 
Result so far: 25.0
If we take 495 away from 581, we end up with 86.
Bring next digit (7) of the dividend behind the 86 and repeat the process: 867 / 99

On to step 5:
99 can be fit into 867 8 times, resulting in a remainder of 75.
Put 8 as the next digit of the answer. 
Result so far: 258.0
Subtracting 792 from 867 leaves us with 75.
Fetch the next digit (0) from the dividend, attach it to 75 and continue: 750 / 99

Going ahead to step 6:
750 divided by 99 is 7 with a remainder of 57.
The number 7 becomes the next digit in our result. 
Result so far: 2587.0
If we subtract 693 from 750, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 7:
When dividing 570 by 99, we get 5 with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 2587.5
Subtract 495 from 570 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 8:
If we divide 750 by 99, we get 7 and a remainder of 57.
Record the quotient 7 as the next digit in the result. 
Result so far: 2587.57
Subtract 693 from 750 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 9:
570 divided by 99 is 5 with a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 2587.575
If we subtract 495 from 570, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 10:
If we divide 750 by 99, we get 7 and a remainder of 57.
The next digit of our result is 7. 
Result so far: 2587.5757
Subtract 693 from 750 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 11:
When dividing 570 by 99, we get 5 with a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 2587.57575
The remainder is 75 after subtracting 495 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 12:
When dividing 750 by 99, we get 7 with a remainder of 57.
Use 7 as the next digit of our solution. 
Result so far: 2587.575757
The remainder is 57 after subtracting 693 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 13:
570 divided by 99 is 5 with a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 2587.5757575
Subtracting 495 from 570 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 14:
The number 99 fits into 750 7 times, leaving a remainder of 57.
The number 7 becomes the next digit in our result. 
Result so far: 2587.57575757
If we subtract 693 from 750, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

After the division, we end up with 2587.57575757 and a remainder of 5.7e-08.
