12687806 ÷ 596 
Let's see how many times 596 fits into 12687806.

On to step 1:
When dividing 1 by 596, we get 0 with 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.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 596

Going ahead to step 2:
The number 596 fits into 12 0 times, leaving a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Take the next digit (6) from the dividend and append it to 12, then repeat: 126 / 596

Going ahead to step 3:
If we divide 126 by 596, we get 0 and a remainder of 126.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 126 to get 126.
Take the next digit (8) from the dividend and append it to 126, then repeat: 1268 / 596

Advancing to step 4:
1268 divided by 596 is 2 with a remainder of 76.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 1192 from 1268 to get 76.
Fetch the next digit (7) from the dividend, attach it to 76 and continue: 767 / 596

Going ahead to step 5:
596 goes into 767 1 times with a remainder of 171.
The next digit of our result is 1. 
Result so far: 21.0
Deduct 596 from 767 and we're left with 171.
Grab the next digit (8) from the dividend, add it to 171, then carry on: 1718 / 596

Going ahead to step 6:
1718 divided by 596 is 2 with a remainder of 526.
Write down 2 as next digit of the result. 
Result so far: 212.0
If we take 1192 away from 1718, we end up with 526.
Append the next digit (0) from the dividend to 526 and continue with: 5260 / 596

Step 7:
When dividing 5260 by 596, we get 8 with a remainder of 492.
Write down 8 as next digit of the result. 
Result so far: 2128.0
Subtract 4768 from 5260 to get 492.
Append the next digit (6) from the dividend to 492 and continue with: 4926 / 596

Let's proceed to step 8:
If we divide 4926 by 596, we get 8 and a remainder of 158.
The number 8 becomes the next digit in our result. 
Result so far: 21288.0
Subtracting 4768 from 4926 leaves us with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

On to step 9:
1580 divided by 596 is 2 with a remainder of 388.
Put 2 as the next digit of the answer. 
Result so far: 21288.2
Deduct 1192 from 1580 and we're left with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Moving on to step 10:
596 can be fit into 3880 6 times, resulting in a remainder of 304.
Write down 6 as next digit of the result. 
Result so far: 21288.26
Subtracting 3576 from 3880 leaves us with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Let's proceed to step 11:
3040 divided by 596 is 5 with a remainder of 60.
The next digit of our result is 5. 
Result so far: 21288.265
Subtracting 2980 from 3040 leaves us 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.

Advancing to step 12:
600 divided by 596 is 1 with a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 21288.2651
Subtracting 596 from 600 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 13:
If we divide 40 by 596, we get 0 and a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 21288.2651
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 14:
596 can be fit into 400 0 times, resulting in a remainder of 400.
The number 0 becomes the next digit in our result. 
Result so far: 21288.2651
If we subtract 0 from 400, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

After the division, we end up with 21288.2651 and a remainder of 4e-05.
