If we subtract 0 from 2, we get 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 917

On to step 2:
The number 917 fits into 25 0 times, leaving a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Grab the next digit (5) from the dividend, add it to 25, then carry on: 255 / 917

On to step 3:
The number 917 fits into 255 0 times, leaving a remainder of 255.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 255 after subtracting 0 from 255.
Include the next digit (9) from the dividend after 255, then repeat: 2559 / 917

Step 4:
2559 divided by 917 is 2 with a remainder of 725.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 1834 from 2559 to get 725.
Include the next digit (1) from the dividend after 725, then repeat: 7251 / 917

On to step 5:
7251 divided by 917 is 7 with a remainder of 832.
Put 7 as the next digit of the answer. 
Result so far: 27.0
Deduct 6419 from 7251 and we're left with 832.
Fetch the next digit (3) from the dividend, attach it to 832 and continue: 8323 / 917

Step 6:
When dividing 8323 by 917, we get 9 with a remainder of 70.
Record the quotient 9 as the next digit in the result. 
Result so far: 279.0
The remainder is 70 after subtracting 8253 from 8323.
Append the next digit (7) from the dividend to 70 and continue with: 707 / 917

Let's proceed to step 7:
The number 917 fits into 707 0 times, leaving a remainder of 707.
The next digit of our result is 0. 
Result so far: 2790.0
If we subtract 0 from 707, we get 707.
Bring next digit (5) of the dividend behind the 707 and repeat the process: 7075 / 917

Moving on to step 8:
When dividing 7075 by 917, we get 7 with a remainder of 656.
The next digit of our result is 7. 
Result so far: 27907.0
Deduct 6419 from 7075 and we're left with 656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

Advancing to step 9:
When dividing 6560 by 917, we get 7 with a remainder of 141.
Use 7 as the next digit of our solution. 
Result so far: 27907.7
If we take 6419 away from 6560, we end up with 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Let's proceed to step 10:
When dividing 1410 by 917, we get 1 with a remainder of 493.
Use 1 as the next digit of our solution. 
Result so far: 27907.71
If we take 917 away from 1410, we end up with 493.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4930, and continue the process.

Moving on to step 11:
If we divide 4930 by 917, we get 5 and a remainder of 345.
Put 5 as the next digit of the answer. 
Result so far: 27907.715
If we take 4585 away from 4930, we end up with 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Advancing to step 12:
The number 917 fits into 3450 3 times, leaving a remainder of 699.
Put 3 as the next digit of the answer. 
Result so far: 27907.7153
Subtracting 2751 from 3450 leaves us with 699.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6990, and continue the process.

Going ahead to step 13:
6990 divided by 917 is 7 with a remainder of 571.
The next digit of our result is 7. 
Result so far: 27907.71537
If we take 6419 away from 6990, we end up with 571.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5710, and continue the process.

Let's proceed to step 14:
If we divide 5710 by 917, we get 6 and a remainder of 208.
Use 6 as the next digit of our solution. 
Result so far: 27907.715376
If we subtract 5502 from 5710, we get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Moving on to step 15:
2080 divided by 917 is 2 with a remainder of 246.
Record the quotient 2 as the next digit in the result. 
Result so far: 27907.7153762
If we subtract 1834 from 2080, we get 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Advancing to step 16:
The number 917 fits into 2460 2 times, leaving a remainder of 626.
The number 2 becomes the next digit in our result. 
Result so far: 27907.71537622
If we subtract 1834 from 2460, we get 626.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6260, and continue the process.

The final outcome is 27907.71537622, with a leftover of 6.26e-07.
