We divide 728454 by 86
We want to figure out the number of times 728454 can be divided by 86.

Step 1:
86 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 86

Let's proceed to step 2:
72 divided by 86 is 0 with a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Append the next digit (8) from the dividend to 72 and continue with: 728 / 86

Going ahead to step 3:
When dividing 728 by 86, we get 8 with a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Deduct 688 from 728 and we're left with 40.
Grab the next digit (4) from the dividend, add it to 40, then carry on: 404 / 86

Going ahead to step 4:
The number 86 fits into 404 4 times, leaving a remainder of 60.
The number 4 becomes the next digit in our result. 
Result so far: 84.0
The remainder is 60 after subtracting 344 from 404.
Take the next digit (5) from the dividend and append it to 60, then repeat: 605 / 86

On to step 5:
The number 86 fits into 605 7 times, leaving a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 847.0
Deduct 602 from 605 and we're left with 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 86

On to step 6:
If we divide 34 by 86, we get 0 and a remainder of 34.
Write down 0 as next digit of the result. 
Result so far: 8470.0
If we take 0 away from 34, 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 7:
The number 86 fits into 340 3 times, leaving a remainder of 82.
Record the quotient 3 as the next digit in the result. 
Result so far: 8470.3
If we subtract 258 from 340, we 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 8:
820 divided by 86 is 9 with a remainder of 46.
Use 9 as the next digit of our solution. 
Result so far: 8470.39
Subtracting 774 from 820 leaves us 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.

Advancing to step 9:
When dividing 460 by 86, we get 5 with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 8470.395
The remainder is 30 after subtracting 430 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 10:
The number 86 fits into 300 3 times, leaving a remainder of 42.
Write down 3 as next digit of the result. 
Result so far: 8470.3953
The remainder is 42 after subtracting 258 from 300.
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 11:
420 divided by 86 is 4 with a remainder of 76.
Put 4 as the next digit of the answer. 
Result so far: 8470.39534
Subtracting 344 from 420 leaves us 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.

Going ahead to step 12:
If we divide 760 by 86, we get 8 and a remainder of 72.
Record the quotient 8 as the next digit in the result. 
Result so far: 8470.395348
Deduct 688 from 760 and we're left with 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 13:
720 divided by 86 is 8 with a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 8470.3953488
Deduct 688 from 720 and we're left with 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 result is 8470.3953488 with a remainder of 3.2e-07.
