We look at the division of 12987168 by 709 
We want to divide 12987168 by 709.

On to step 1:
709 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 709

Going ahead to step 2:
The number 709 fits into 12 0 times, leaving a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Append the next digit (9) from the dividend to 12 and continue with: 129 / 709

Going ahead to step 3:
When dividing 129 by 709, we get 0 with a remainder of 129.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 129, we get 129.
Include the next digit (8) from the dividend after 129, then repeat: 1298 / 709

Let's proceed to step 4:
If we divide 1298 by 709, we get 1 and a remainder of 589.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 589 after subtracting 709 from 1298.
Grab the next digit (7) from the dividend, add it to 589, then carry on: 5897 / 709

Let's proceed to step 5:
When dividing 5897 by 709, we get 8 with a remainder of 225.
Write down 8 as next digit of the result. 
Result so far: 18.0
Subtracting 5672 from 5897 leaves us with 225.
Bring next digit (1) of the dividend behind the 225 and repeat the process: 2251 / 709

Moving on to step 6:
If we divide 2251 by 709, we get 3 and a remainder of 124.
Write down 3 as next digit of the result. 
Result so far: 183.0
Subtract 2127 from 2251 to get 124.
Grab the next digit (6) from the dividend, add it to 124, then carry on: 1246 / 709

Step 7:
When dividing 1246 by 709, we get 1 with a remainder of 537.
Put 1 as the next digit of the answer. 
Result so far: 1831.0
Deduct 709 from 1246 and we're left with 537.
Fetch the next digit (8) from the dividend, attach it to 537 and continue: 5378 / 709

On to step 8:
If we divide 5378 by 709, we get 7 and a remainder of 415.
Put 7 as the next digit of the answer. 
Result so far: 18317.0
Deduct 4963 from 5378 and we're left with 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

On to step 9:
709 goes into 4150 5 times with a remainder of 605.
The number 5 becomes the next digit in our result. 
Result so far: 18317.5
If we take 3545 away from 4150, we end up with 605.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6050, and continue the process.

Moving on to step 10:
If we divide 6050 by 709, we get 8 and a remainder of 378.
Use 8 as the next digit of our solution. 
Result so far: 18317.58
If we subtract 5672 from 6050, we get 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Let's proceed to step 11:
The number 709 fits into 3780 5 times, leaving a remainder of 235.
Record the quotient 5 as the next digit in the result. 
Result so far: 18317.585
If we subtract 3545 from 3780, we get 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Step 12:
2350 divided by 709 is 3 with a remainder of 223.
The next digit of our result is 3. 
Result so far: 18317.5853
If we subtract 2127 from 2350, we get 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

On to step 13:
If we divide 2230 by 709, we get 3 and a remainder of 103.
Write down 3 as next digit of the result. 
Result so far: 18317.58533
Subtract 2127 from 2230 to get 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Our division results in 18317.58533 with a remaining 0.000103.
