We look at the division of 13586 by 86 
We want to divide 13586 by 86.

Moving on to step 1:
1 divided by 86 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 86

Moving on to step 2:
86 can be fit into 13 0 times, resulting in a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Fetch the next digit (5) from the dividend, attach it to 13 and continue: 135 / 86

Advancing to step 3:
86 goes into 135 1 times with a remainder of 49.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 49 after subtracting 86 from 135.
Append the next digit (8) from the dividend to 49 and continue with: 498 / 86

Going ahead to step 4:
86 can be fit into 498 5 times, resulting in a remainder of 68.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we subtract 430 from 498, we get 68.
Include the next digit (6) from the dividend after 68, then repeat: 686 / 86

On to step 5:
When dividing 686 by 86, we get 7 with a remainder of 84.
Write down 7 as next digit of the result. 
Result so far: 157.0
Subtract 602 from 686 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 6:
The number 86 fits into 840 9 times, leaving a remainder of 66.
Put 9 as the next digit of the answer. 
Result so far: 157.9
The remainder is 66 after subtracting 774 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 7:
The number 86 fits into 660 7 times, leaving a remainder of 58.
Use 7 as the next digit of our solution. 
Result so far: 157.97
Subtracting 602 from 660 leaves us 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 8:
86 can be fit into 580 6 times, resulting in a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 157.976
Subtract 516 from 580 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 9:
86 can be fit into 640 7 times, resulting in a remainder of 38.
The next digit of our result is 7. 
Result so far: 157.9767
If we subtract 602 from 640, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 10:
86 can be fit into 380 4 times, resulting in a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 157.97674
If we take 344 away from 380, we end up 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.

Step 11:
If we divide 360 by 86, we get 4 and a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 157.976744
If we take 344 away from 360, we end up with 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 quotient of the division is 157.976744, and the remainder is 1.6e-06.
