We're dividing 140579 by 86 
We're looking to find how many times 86 goes into 140579.

Going ahead to step 1:
86 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 86

Step 2:
If we divide 14 by 86, we get 0 and a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 14, we end up with 14.
Bring next digit (0) of the dividend behind the 14 and repeat the process: 140 / 86

Let's proceed to step 3:
When dividing 140 by 86, we get 1 with a remainder of 54.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 54 after subtracting 86 from 140.
Include the next digit (5) from the dividend after 54, then repeat: 545 / 86

Let's proceed to step 4:
86 can be fit into 545 6 times, resulting in a remainder of 29.
The next digit of our result is 6. 
Result so far: 16.0
The remainder is 29 after subtracting 516 from 545.
Fetch the next digit (7) from the dividend, attach it to 29 and continue: 297 / 86

Advancing to step 5:
When dividing 297 by 86, we get 3 with a remainder of 39.
Put 3 as the next digit of the answer. 
Result so far: 163.0
Subtract 258 from 297 to get 39.
Grab the next digit (9) from the dividend, add it to 39, then carry on: 399 / 86

Step 6:
The number 86 fits into 399 4 times, leaving a remainder of 55.
Write down 4 as next digit of the result. 
Result so far: 1634.0
Subtracting 344 from 399 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 7:
If we divide 550 by 86, we get 6 and a remainder of 34.
The number 6 becomes the next digit in our result. 
Result so far: 1634.6
Deduct 516 from 550 and we're left 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.

Moving on to step 8:
The number 86 fits into 340 3 times, leaving a remainder of 82.
Put 3 as the next digit of the answer. 
Result so far: 1634.63
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 9:
If we divide 820 by 86, we get 9 and a remainder of 46.
Record the quotient 9 as the next digit in the result. 
Result so far: 1634.639
Subtract 774 from 820 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 10:
460 divided by 86 is 5 with a remainder of 30.
The next digit of our result is 5. 
Result so far: 1634.6395
If we subtract 430 from 460, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 11:
86 goes into 300 3 times with a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 1634.63953
If we subtract 258 from 300, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 12:
86 can be fit into 420 4 times, resulting in a remainder of 76.
The next digit of our result is 4. 
Result so far: 1634.639534
If we take 344 away from 420, we end up 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.

On to step 13:
86 can be fit into 760 8 times, resulting in a remainder of 72.
The number 8 becomes the next digit in our result. 
Result so far: 1634.6395348
The remainder is 72 after subtracting 688 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 14:
86 goes into 720 8 times with a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 1634.63953488
Subtracting 688 from 720 leaves us 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 quotient of the division is 1634.63953488, and the remainder is 3.2e-08.
