We look at the division of 104550 by 86 
Let's see how many times 86 fits into 104550.

Let's proceed to step 1:
When dividing 1 by 86, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 86

Let's proceed to step 2:
86 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 10 to get 10.
Take the next digit (4) from the dividend and append it to 10, then repeat: 104 / 86

On to step 3:
If we divide 104 by 86, we get 1 and a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 18 after subtracting 86 from 104.
Include the next digit (5) from the dividend after 18, then repeat: 185 / 86

Moving on to step 4:
If we divide 185 by 86, we get 2 and a remainder of 13.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtract 172 from 185 to get 13.
Take the next digit (5) from the dividend and append it to 13, then repeat: 135 / 86

Moving on to step 5:
86 goes into 135 1 times with a remainder of 49.
Write down 1 as next digit of the result. 
Result so far: 121.0
Subtract 86 from 135 to get 49.
Grab the next digit (0) from the dividend, add it to 49, then carry on: 490 / 86

Let's proceed to step 6:
86 goes into 490 5 times with a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 1215.0
If we take 430 away from 490, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 7:
600 divided by 86 is 6 with a remainder of 84.
Record the quotient 6 as the next digit in the result. 
Result so far: 1215.6
The remainder is 84 after subtracting 516 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 8:
840 divided by 86 is 9 with a remainder of 66.
Use 9 as the next digit of our solution. 
Result so far: 1215.69
Deduct 774 from 840 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 9:
When dividing 660 by 86, we get 7 with a remainder of 58.
Use 7 as the next digit of our solution. 
Result so far: 1215.697
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.

Moving on to step 10:
If we divide 580 by 86, we get 6 and a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 1215.6976
The remainder is 64 after subtracting 516 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 11:
86 can be fit into 640 7 times, resulting in a remainder of 38.
The number 7 becomes the next digit in our result. 
Result so far: 1215.69767
Subtracting 602 from 640 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 12:
When dividing 380 by 86, we get 4 with a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 1215.697674
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 13:
86 goes into 360 4 times with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 1215.6976744
Subtract 344 from 360 to 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 1215.6976744 with a remainder of 1.6e-07.
