1288836 divided by 686 
Let's see how many times 686 fits into 1288836.

On to step 1:
686 goes into 1 0 times 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.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 686

Let's proceed to step 2:
If we divide 12 by 686, we get 0 and a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Include the next digit (8) from the dividend after 12, then repeat: 128 / 686

Going ahead to step 3:
When dividing 128 by 686, we get 0 with a remainder of 128.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 128, we get 128.
Bring next digit (8) of the dividend behind the 128 and repeat the process: 1288 / 686

Advancing to step 4:
1288 divided by 686 is 1 with a remainder of 602.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 686 from 1288, we get 602.
Take the next digit (8) from the dividend and append it to 602, then repeat: 6028 / 686

On to step 5:
686 goes into 6028 8 times with a remainder of 540.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
The remainder is 540 after subtracting 5488 from 6028.
Bring next digit (3) of the dividend behind the 540 and repeat the process: 5403 / 686

On to step 6:
If we divide 5403 by 686, we get 7 and a remainder of 601.
Use 7 as the next digit of our solution. 
Result so far: 187.0
If we subtract 4802 from 5403, we get 601.
Bring next digit (6) of the dividend behind the 601 and repeat the process: 6016 / 686

Step 7:
686 can be fit into 6016 8 times, resulting in a remainder of 528.
The next digit of our result is 8. 
Result so far: 1878.0
Subtract 5488 from 6016 to get 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Moving on to step 8:
5280 divided by 686 is 7 with a remainder of 478.
Record the quotient 7 as the next digit in the result. 
Result so far: 1878.7
Deduct 4802 from 5280 and we're left with 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

Step 9:
4780 divided by 686 is 6 with a remainder of 664.
Write down 6 as next digit of the result. 
Result so far: 1878.76
The remainder is 664 after subtracting 4116 from 4780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6640, and continue the process.

Moving on to step 10:
686 can be fit into 6640 9 times, resulting in a remainder of 466.
The number 9 becomes the next digit in our result. 
Result so far: 1878.769
If we subtract 6174 from 6640, we get 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

Advancing to step 11:
686 can be fit into 4660 6 times, resulting in a remainder of 544.
Write down 6 as next digit of the result. 
Result so far: 1878.7696
Subtract 4116 from 4660 to get 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Going ahead to step 12:
686 goes into 5440 7 times with a remainder of 638.
The next digit of our result is 7. 
Result so far: 1878.76967
Subtract 4802 from 5440 to get 638.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6380, and continue the process.

On to step 13:
686 goes into 6380 9 times with a remainder of 206.
Write down 9 as next digit of the result. 
Result so far: 1878.769679
If we take 6174 away from 6380, we end up with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Let's proceed to step 14:
2060 divided by 686 is 3 with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 1878.7696793
Deduct 2058 from 2060 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 15:
If we divide 20 by 686, we get 0 and a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 1878.7696793
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The quotient of the division is 1878.7696793, and the remainder is 2e-08.
