287686 divided by 13 
We want to divide 287686 by 13.

Advancing to step 1:
When dividing 2 by 13, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 13

On to step 2:
13 can be fit into 28 2 times, resulting in a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 26 away from 28, we end up with 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 13

Advancing to step 3:
The number 13 fits into 27 2 times, leaving a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 22.0
Deduct 26 from 27 and we're left with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 13

Advancing to step 4:
When dividing 16 by 13, we get 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 221.0
Subtracting 13 from 16 leaves us with 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 13

On to step 5:
If we divide 38 by 13, we get 2 and a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 2212.0
If we take 26 away from 38, we end up with 12.
Grab the next digit (6) from the dividend, add it to 12, then carry on: 126 / 13

Going ahead to step 6:
13 goes into 126 9 times with a remainder of 9.
The next digit of our result is 9. 
Result so far: 22129.0
Deduct 117 from 126 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
13 can be fit into 90 6 times, resulting in a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 22129.6
Subtracting 78 from 90 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 8:
13 goes into 120 9 times with a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 22129.69
Subtract 117 from 120 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 9:
If we divide 30 by 13, we get 2 and a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 22129.692
If we subtract 26 from 30, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 10:
13 goes into 40 3 times with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 22129.6923
Subtract 39 from 40 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 11:
When dividing 10 by 13, we get 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 22129.6923
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 12:
When dividing 100 by 13, we get 7 with a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 22129.692307
The remainder is 9 after subtracting 91 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 13:
90 divided by 13 is 6 with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 22129.6923076
Deduct 78 from 90 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 14:
13 goes into 120 9 times with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 22129.69230769
Subtract 117 from 120 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The final outcome is 22129.69230769, with a leftover of 3e-09.
