We're dividing 87138768 by 685 
We're looking to find how many times 685 goes into 87138768.

Moving on to step 1:
685 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 685

Let's proceed to step 2:
The number 685 fits into 87 0 times, leaving a remainder of 87.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 87 and we're left with 87.
Include the next digit (1) from the dividend after 87, then repeat: 871 / 685

Going ahead to step 3:
If we divide 871 by 685, we get 1 and a remainder of 186.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 186 after subtracting 685 from 871.
Bring next digit (3) of the dividend behind the 186 and repeat the process: 1863 / 685

Moving on to step 4:
685 goes into 1863 2 times with a remainder of 493.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtract 1370 from 1863 to get 493.
Include the next digit (8) from the dividend after 493, then repeat: 4938 / 685

Let's proceed to step 5:
When dividing 4938 by 685, we get 7 with a remainder of 143.
Put 7 as the next digit of the answer. 
Result so far: 127.0
Subtracting 4795 from 4938 leaves us with 143.
Append the next digit (7) from the dividend to 143 and continue with: 1437 / 685

Going ahead to step 6:
When dividing 1437 by 685, we get 2 with a remainder of 67.
Write down 2 as next digit of the result. 
Result so far: 1272.0
If we subtract 1370 from 1437, we get 67.
Fetch the next digit (6) from the dividend, attach it to 67 and continue: 676 / 685

On to step 7:
685 can be fit into 676 0 times, resulting in a remainder of 676.
Record the quotient 0 as the next digit in the result. 
Result so far: 12720.0
Deduct 0 from 676 and we're left with 676.
Bring next digit (8) of the dividend behind the 676 and repeat the process: 6768 / 685

On to step 8:
The number 685 fits into 6768 9 times, leaving a remainder of 603.
Put 9 as the next digit of the answer. 
Result so far: 127209.0
Deduct 6165 from 6768 and we're left with 603.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6030, and continue the process.

Going ahead to step 9:
6030 divided by 685 is 8 with a remainder of 550.
Record the quotient 8 as the next digit in the result. 
Result so far: 127209.8
If we take 5480 away from 6030, we end up with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

On to step 10:
If we divide 5500 by 685, we get 8 and a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 127209.88
If we take 5480 away from 5500, 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 final result is 127209.88 with a remainder of 0.02.
