We look at the division of 140728 by 86 
Let's see how many times 86 fits into 140728.

Advancing to step 1:
If we divide 1 by 86, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 86

Step 2:
When dividing 14 by 86, we get 0 with a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 14, we get 14.
Fetch the next digit (0) from the dividend, attach it to 14 and continue: 140 / 86

Step 3:
The number 86 fits into 140 1 times, leaving a remainder of 54.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 54 after subtracting 86 from 140.
Append the next digit (7) from the dividend to 54 and continue with: 547 / 86

Moving on to step 4:
547 divided by 86 is 6 with a remainder of 31.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtract 516 from 547 to get 31.
Fetch the next digit (2) from the dividend, attach it to 31 and continue: 312 / 86

Let's proceed to step 5:
If we divide 312 by 86, we get 3 and a remainder of 54.
The next digit of our result is 3. 
Result so far: 163.0
Deduct 258 from 312 and we're left with 54.
Take the next digit (8) from the dividend and append it to 54, then repeat: 548 / 86

Let's proceed to step 6:
86 can be fit into 548 6 times, resulting in a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 1636.0
Subtract 516 from 548 to 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.

Step 7:
86 can be fit into 320 3 times, resulting in a remainder of 62.
Use 3 as the next digit of our solution. 
Result so far: 1636.3
If we take 258 away from 320, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 8:
86 goes into 620 7 times with a remainder of 18.
Record the quotient 7 as the next digit in the result. 
Result so far: 1636.37
If we subtract 602 from 620, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 9:
86 goes into 180 2 times with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 1636.372
If we subtract 172 from 180, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 10:
The number 86 fits into 80 0 times, leaving a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 1636.372
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 11:
86 goes into 800 9 times with a remainder of 26.
The number 9 becomes the next digit in our result. 
Result so far: 1636.37209
Deduct 774 from 800 and we're left 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.

Advancing to step 12:
260 divided by 86 is 3 with a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 1636.372093
Subtract 258 from 260 to 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.

Let's proceed to step 13:
86 goes into 20 0 times with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 1636.372093
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 14:
86 can be fit into 200 2 times, resulting in a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 1636.37209302
Deduct 172 from 200 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Our division results in 1636.37209302 with a remaining 2.8e-08.
