We look at the division of 172866 by 71 
Let's see how many times 71 fits into 172866.

Moving on to step 1:
71 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 71

Moving on to step 2:
The number 71 fits into 17 0 times, leaving a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Include the next digit (2) from the dividend after 17, then repeat: 172 / 71

Step 3:
If we divide 172 by 71, we get 2 and a remainder of 30.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 142 from 172 and we're left with 30.
Fetch the next digit (8) from the dividend, attach it to 30 and continue: 308 / 71

Moving on to step 4:
When dividing 308 by 71, we get 4 with a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 24.0
The remainder is 24 after subtracting 284 from 308.
Bring next digit (6) of the dividend behind the 24 and repeat the process: 246 / 71

Going ahead to step 5:
246 divided by 71 is 3 with a remainder of 33.
Record the quotient 3 as the next digit in the result. 
Result so far: 243.0
If we subtract 213 from 246, we get 33.
Append the next digit (6) from the dividend to 33 and continue with: 336 / 71

Moving on to step 6:
If we divide 336 by 71, we get 4 and a remainder of 52.
Record the quotient 4 as the next digit in the result. 
Result so far: 2434.0
Deduct 284 from 336 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 7:
If we divide 520 by 71, we get 7 and a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 2434.7
The remainder is 23 after subtracting 497 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 8:
If we divide 230 by 71, we get 3 and a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 2434.73
The remainder is 17 after subtracting 213 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 9:
170 divided by 71 is 2 with a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 2434.732
The remainder is 28 after subtracting 142 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 10:
When dividing 280 by 71, we get 3 with a remainder of 67.
The next digit of our result is 3. 
Result so far: 2434.7323
Deduct 213 from 280 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Step 11:
670 divided by 71 is 9 with a remainder of 31.
Write down 9 as next digit of the result. 
Result so far: 2434.73239
The remainder is 31 after subtracting 639 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 12:
If we divide 310 by 71, we get 4 and a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 2434.732394
Subtract 284 from 310 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 13:
260 divided by 71 is 3 with a remainder of 47.
Put 3 as the next digit of the answer. 
Result so far: 2434.7323943
Subtract 213 from 260 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 14:
71 goes into 470 6 times with a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 2434.73239436
Subtract 426 from 470 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The quotient of the division is 2434.73239436, and the remainder is 4.4e-08.
