12327993 ÷ 686 
Let's see how many times 686 fits into 12327993.

Going ahead to step 1:
When dividing 1 by 686, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 686

Step 2:
686 can be fit into 12 0 times, resulting in a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Append the next digit (3) from the dividend to 12 and continue with: 123 / 686

Going ahead to step 3:
The number 686 fits into 123 0 times, leaving a remainder of 123.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 123, we end up with 123.
Bring next digit (2) of the dividend behind the 123 and repeat the process: 1232 / 686

Advancing to step 4:
If we divide 1232 by 686, we get 1 and a remainder of 546.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 546 after subtracting 686 from 1232.
Append the next digit (7) from the dividend to 546 and continue with: 5467 / 686

On to step 5:
5467 divided by 686 is 7 with a remainder of 665.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Subtract 4802 from 5467 to get 665.
Grab the next digit (9) from the dividend, add it to 665, then carry on: 6659 / 686

On to step 6:
686 goes into 6659 9 times with a remainder of 485.
Use 9 as the next digit of our solution. 
Result so far: 179.0
The remainder is 485 after subtracting 6174 from 6659.
Fetch the next digit (9) from the dividend, attach it to 485 and continue: 4859 / 686

Moving on to step 7:
686 can be fit into 4859 7 times, resulting in a remainder of 57.
Use 7 as the next digit of our solution. 
Result so far: 1797.0
The remainder is 57 after subtracting 4802 from 4859.
Include the next digit (3) from the dividend after 57, then repeat: 573 / 686

Advancing to step 8:
When dividing 573 by 686, we get 0 with a remainder of 573.
Write down 0 as next digit of the result. 
Result so far: 17970.0
Deduct 0 from 573 and we're left with 573.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5730, and continue the process.

Moving on to step 9:
The number 686 fits into 5730 8 times, leaving a remainder of 242.
Write down 8 as next digit of the result. 
Result so far: 17970.8
The remainder is 242 after subtracting 5488 from 5730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Going ahead to step 10:
2420 divided by 686 is 3 with a remainder of 362.
Record the quotient 3 as the next digit in the result. 
Result so far: 17970.83
Subtract 2058 from 2420 to get 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Going ahead to step 11:
If we divide 3620 by 686, we get 5 and a remainder of 190.
Use 5 as the next digit of our solution. 
Result so far: 17970.835
If we subtract 3430 from 3620, we get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

On to step 12:
If we divide 1900 by 686, we get 2 and a remainder of 528.
Put 2 as the next digit of the answer. 
Result so far: 17970.8352
Subtracting 1372 from 1900 leaves us with 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Advancing to step 13:
686 can be fit into 5280 7 times, resulting in a remainder of 478.
Use 7 as the next digit of our solution. 
Result so far: 17970.83527
If we subtract 4802 from 5280, we get 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

Going ahead to step 14:
686 can be fit into 4780 6 times, resulting in a remainder of 664.
Use 6 as the next digit of our solution. 
Result so far: 17970.835276
Deduct 4116 from 4780 and we're left with 664.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6640, and continue the process.

Advancing to step 15:
When dividing 6640 by 686, we get 9 with a remainder of 466.
Record the quotient 9 as the next digit in the result. 
Result so far: 17970.8352769
Subtracting 6174 from 6640 leaves us with 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

On to step 16:
If we divide 4660 by 686, we get 6 and a remainder of 544.
The number 6 becomes the next digit in our result. 
Result so far: 17970.83527696
If we subtract 4116 from 4660, we 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.

Our division results in 17970.83527696 with a remaining 5.44e-07.
