We look at the division of 78187527 by 647 
Let's see how many times 647 fits into 78187527.

Moving on to step 1:
647 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 647

On to step 2:
647 can be fit into 78 0 times, resulting in a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Bring next digit (1) of the dividend behind the 78 and repeat the process: 781 / 647

Let's proceed to step 3:
When dividing 781 by 647, we get 1 with a remainder of 134.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 647 from 781, we get 134.
Include the next digit (8) from the dividend after 134, then repeat: 1348 / 647

Let's proceed to step 4:
647 can be fit into 1348 2 times, resulting in a remainder of 54.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Deduct 1294 from 1348 and we're left with 54.
Include the next digit (7) from the dividend after 54, then repeat: 547 / 647

Going ahead to step 5:
The number 647 fits into 547 0 times, leaving a remainder of 547.
Write down 0 as next digit of the result. 
Result so far: 120.0
Deduct 0 from 547 and we're left with 547.
Include the next digit (5) from the dividend after 547, then repeat: 5475 / 647

Moving on to step 6:
647 goes into 5475 8 times with a remainder of 299.
The next digit of our result is 8. 
Result so far: 1208.0
The remainder is 299 after subtracting 5176 from 5475.
Fetch the next digit (2) from the dividend, attach it to 299 and continue: 2992 / 647

Let's proceed to step 7:
If we divide 2992 by 647, we get 4 and a remainder of 404.
Record the quotient 4 as the next digit in the result. 
Result so far: 12084.0
If we subtract 2588 from 2992, we get 404.
Take the next digit (7) from the dividend and append it to 404, then repeat: 4047 / 647

On to step 8:
When dividing 4047 by 647, we get 6 with a remainder of 165.
Record the quotient 6 as the next digit in the result. 
Result so far: 120846.0
Subtract 3882 from 4047 to get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Step 9:
When dividing 1650 by 647, we get 2 with a remainder of 356.
The next digit of our result is 2. 
Result so far: 120846.2
Deduct 1294 from 1650 and we're left with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Step 10:
3560 divided by 647 is 5 with a remainder of 325.
Record the quotient 5 as the next digit in the result. 
Result so far: 120846.25
Subtract 3235 from 3560 to get 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Going ahead to step 11:
When dividing 3250 by 647, we get 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 120846.255
If we subtract 3235 from 3250, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Our division results in 120846.255 with a remaining 0.0015.
