On to step 3:
871 divided by 216 is 4 with a remainder of 7.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 864 from 871 and we're left with 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 216

Step 4:
216 can be fit into 77 0 times, resulting in a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
Deduct 0 from 77 and we're left with 77.
Grab the next digit (3) from the dividend, add it to 77, then carry on: 773 / 216

Moving on to step 5:
The number 216 fits into 773 3 times, leaving a remainder of 125.
The next digit of our result is 3. 
Result so far: 403.0
Subtract 648 from 773 to get 125.
Grab the next digit (9) from the dividend, add it to 125, then carry on: 1259 / 216

Advancing to step 6:
1259 divided by 216 is 5 with a remainder of 179.
The number 5 becomes the next digit in our result. 
Result so far: 4035.0
The remainder is 179 after subtracting 1080 from 1259.
Grab the next digit (6) from the dividend, add it to 179, then carry on: 1796 / 216

Step 7:
If we divide 1796 by 216, we get 8 and a remainder of 68.
The next digit of our result is 8. 
Result so far: 40358.0
If we subtract 1728 from 1796, we get 68.
Fetch the next digit (2) from the dividend, attach it to 68 and continue: 682 / 216

Moving on to step 8:
216 goes into 682 3 times with a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 403583.0
Subtract 648 from 682 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 9:
If we divide 340 by 216, we get 1 and a remainder of 124.
Record the quotient 1 as the next digit in the result. 
Result so far: 403583.1
Deduct 216 from 340 and we're left with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Advancing to step 10:
The number 216 fits into 1240 5 times, leaving a remainder of 160.
Write down 5 as next digit of the result. 
Result so far: 403583.15
Subtract 1080 from 1240 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 11:
1600 divided by 216 is 7 with a remainder of 88.
The next digit of our result is 7. 
Result so far: 403583.157
The remainder is 88 after subtracting 1512 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 12:
The number 216 fits into 880 4 times, leaving a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 403583.1574
The remainder is 16 after subtracting 864 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 13:
160 divided by 216 is 0 with a remainder of 160.
The number 0 becomes the next digit in our result. 
Result so far: 403583.1574
Subtract 0 from 160 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 14:
If we divide 1600 by 216, we get 7 and a remainder of 88.
Write down 7 as next digit of the result. 
Result so far: 403583.157407
Subtract 1512 from 1600 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

On to step 15:
When dividing 880 by 216, we get 4 with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 403583.1574074
The remainder is 16 after subtracting 864 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 16:
216 goes into 160 0 times with a remainder of 160.
Put 0 as the next digit of the answer. 
Result so far: 403583.1574074
If we take 0 away from 160, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Our division results in 403583.1574074 with a remaining 1.6e-07.
