We look at the division of 7718131 by 781 
Let's see how many times 781 fits into 7718131.

On to step 1:
781 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 781

Step 2:
When dividing 77 by 781, we get 0 with a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Include the next digit (1) from the dividend after 77, then repeat: 771 / 781

On to step 3:
When dividing 771 by 781, we get 0 with a remainder of 771.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 771 and we're left with 771.
Bring next digit (8) of the dividend behind the 771 and repeat the process: 7718 / 781

Going ahead to step 4:
When dividing 7718 by 781, we get 9 with a remainder of 689.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Deduct 7029 from 7718 and we're left with 689.
Fetch the next digit (1) from the dividend, attach it to 689 and continue: 6891 / 781

On to step 5:
781 goes into 6891 8 times with a remainder of 643.
Record the quotient 8 as the next digit in the result. 
Result so far: 98.0
Subtracting 6248 from 6891 leaves us with 643.
Append the next digit (3) from the dividend to 643 and continue with: 6433 / 781

On to step 6:
If we divide 6433 by 781, we get 8 and a remainder of 185.
The number 8 becomes the next digit in our result. 
Result so far: 988.0
The remainder is 185 after subtracting 6248 from 6433.
Bring next digit (1) of the dividend behind the 185 and repeat the process: 1851 / 781

Advancing to step 7:
When dividing 1851 by 781, we get 2 with a remainder of 289.
The next digit of our result is 2. 
Result so far: 9882.0
The remainder is 289 after subtracting 1562 from 1851.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Let's proceed to step 8:
2890 divided by 781 is 3 with a remainder of 547.
Write down 3 as next digit of the result. 
Result so far: 9882.3
Subtract 2343 from 2890 to get 547.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5470, and continue the process.

Going ahead to step 9:
The number 781 fits into 5470 7 times, leaving a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 9882.37
Subtracting 5467 from 5470 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 10:
When dividing 30 by 781, we get 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 9882.37
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 11:
781 goes into 300 0 times with a remainder of 300.
Put 0 as the next digit of the answer. 
Result so far: 9882.37
Subtract 0 from 300 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

After the division, we end up with 9882.37 and a remainder of 0.003.
