728543 divided by 86 
Our goal is to divide 728543 by 86.

Let's proceed to step 1:
86 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 86

Let's proceed to step 2:
The number 86 fits into 72 0 times, leaving a remainder of 72.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 72 and we're left with 72.
Grab the next digit (8) from the dividend, add it to 72, then carry on: 728 / 86

Let's proceed to step 3:
86 goes into 728 8 times with a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 688 from 728, we get 40.
Take the next digit (5) from the dividend and append it to 40, then repeat: 405 / 86

On to step 4:
The number 86 fits into 405 4 times, leaving a remainder of 61.
Record the quotient 4 as the next digit in the result. 
Result so far: 84.0
Subtracting 344 from 405 leaves us with 61.
Take the next digit (4) from the dividend and append it to 61, then repeat: 614 / 86

Step 5:
If we divide 614 by 86, we get 7 and a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 847.0
Deduct 602 from 614 and we're left with 12.
Fetch the next digit (3) from the dividend, attach it to 12 and continue: 123 / 86

Going ahead to step 6:
The number 86 fits into 123 1 times, leaving a remainder of 37.
Use 1 as the next digit of our solution. 
Result so far: 8471.0
Deduct 86 from 123 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 7:
370 divided by 86 is 4 with a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 8471.4
If we take 344 away from 370, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 8:
The number 86 fits into 260 3 times, leaving a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 8471.43
If we subtract 258 from 260, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 9:
86 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 8471.43
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 10:
The number 86 fits into 200 2 times, leaving a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 8471.4302
The remainder is 28 after subtracting 172 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 11:
86 goes into 280 3 times with a remainder of 22.
Record the quotient 3 as the next digit in the result. 
Result so far: 8471.43023
Subtracting 258 from 280 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 12:
If we divide 220 by 86, we get 2 and a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 8471.430232
The remainder is 48 after subtracting 172 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 13:
When dividing 480 by 86, we get 5 with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 8471.4302325
If we take 430 away from 480, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 14:
500 divided by 86 is 5 with a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 8471.43023255
Subtracting 430 from 500 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Our division results in 8471.43023255 with a remaining 7e-08.
