We're dividing 72016 by 86 
We want to divide 72016 by 86.

Let's proceed to step 1:
The number 86 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 86

Moving on to step 2:
72 divided by 86 is 0 with a remainder of 72.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Include the next digit (0) from the dividend after 72, then repeat: 720 / 86

Let's proceed to step 3:
720 divided by 86 is 8 with a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 688 from 720 to get 32.
Bring next digit (1) of the dividend behind the 32 and repeat the process: 321 / 86

Advancing to step 4:
If we divide 321 by 86, we get 3 and a remainder of 63.
Write down 3 as next digit of the result. 
Result so far: 83.0
Subtract 258 from 321 to get 63.
Include the next digit (6) from the dividend after 63, then repeat: 636 / 86

Step 5:
If we divide 636 by 86, we get 7 and a remainder of 34.
The number 7 becomes the next digit in our result. 
Result so far: 837.0
If we take 602 away from 636, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 6:
When dividing 340 by 86, we get 3 with a remainder of 82.
The number 3 becomes the next digit in our result. 
Result so far: 837.3
Subtract 258 from 340 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Let's proceed to step 7:
820 divided by 86 is 9 with a remainder of 46.
The next digit of our result is 9. 
Result so far: 837.39
If we take 774 away from 820, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 8:
460 divided by 86 is 5 with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 837.395
If we take 430 away from 460, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 9:
86 goes into 300 3 times with a remainder of 42.
The next digit of our result is 3. 
Result so far: 837.3953
Deduct 258 from 300 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 10:
86 goes into 420 4 times with a remainder of 76.
Record the quotient 4 as the next digit in the result. 
Result so far: 837.39534
Deduct 344 from 420 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 11:
86 goes into 760 8 times with a remainder of 72.
Write down 8 as next digit of the result. 
Result so far: 837.395348
If we subtract 688 from 760, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 12:
The number 86 fits into 720 8 times, leaving a remainder of 32.
The next digit of our result is 8. 
Result so far: 837.3953488
If we subtract 688 from 720, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final outcome is 837.3953488, with a leftover of 3.2e-07.
