We're dividing 721065 by 86 
Let's see how many times 86 fits into 721065.

On to step 1:
When dividing 7 by 86, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 86

Advancing to step 2:
86 can be fit into 72 0 times, resulting in a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 72 and we're left with 72.
Bring next digit (1) of the dividend behind the 72 and repeat the process: 721 / 86

Let's proceed to step 3:
When dividing 721 by 86, we get 8 with a remainder of 33.
The next digit of our result is 8. 
Result so far: 8.0
The remainder is 33 after subtracting 688 from 721.
Fetch the next digit (0) from the dividend, attach it to 33 and continue: 330 / 86

Moving on to step 4:
86 can be fit into 330 3 times, resulting in a remainder of 72.
Use 3 as the next digit of our solution. 
Result so far: 83.0
Subtract 258 from 330 to get 72.
Take the next digit (6) from the dividend and append it to 72, then repeat: 726 / 86

Advancing to step 5:
When dividing 726 by 86, we get 8 with a remainder of 38.
Put 8 as the next digit of the answer. 
Result so far: 838.0
Subtracting 688 from 726 leaves us with 38.
Fetch the next digit (5) from the dividend, attach it to 38 and continue: 385 / 86

Step 6:
86 goes into 385 4 times with a remainder of 41.
Record the quotient 4 as the next digit in the result. 
Result so far: 8384.0
The remainder is 41 after subtracting 344 from 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 7:
When dividing 410 by 86, we get 4 with a remainder of 66.
The next digit of our result is 4. 
Result so far: 8384.4
Subtract 344 from 410 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 8:
The number 86 fits into 660 7 times, leaving a remainder of 58.
The next digit of our result is 7. 
Result so far: 8384.47
If we take 602 away from 660, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 9:
The number 86 fits into 580 6 times, leaving a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 8384.476
Subtracting 516 from 580 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 10:
86 can be fit into 640 7 times, resulting in a remainder of 38.
Put 7 as the next digit of the answer. 
Result so far: 8384.4767
Subtract 602 from 640 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 11:
380 divided by 86 is 4 with a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 8384.47674
Subtracting 344 from 380 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 12:
86 can be fit into 360 4 times, resulting in a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 8384.476744
If we subtract 344 from 360, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 8384.476744 with a remainder of 1.6e-06.
