Let's divide 86816510 by 685
We're looking to find how many times 685 goes into 86816510.

Advancing to step 1:
The number 685 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 685

Going ahead to step 2:
685 can be fit into 86 0 times, resulting in a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Fetch the next digit (8) from the dividend, attach it to 86 and continue: 868 / 685

Step 3:
685 can be fit into 868 1 times, resulting in a remainder of 183.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 685 away from 868, we end up with 183.
Fetch the next digit (1) from the dividend, attach it to 183 and continue: 1831 / 685

Let's proceed to step 4:
685 goes into 1831 2 times with a remainder of 461.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we take 1370 away from 1831, we end up with 461.
Take the next digit (6) from the dividend and append it to 461, then repeat: 4616 / 685

Step 5:
685 goes into 4616 6 times with a remainder of 506.
The next digit of our result is 6. 
Result so far: 126.0
Subtracting 4110 from 4616 leaves us with 506.
Append the next digit (5) from the dividend to 506 and continue with: 5065 / 685

Going ahead to step 6:
The number 685 fits into 5065 7 times, leaving a remainder of 270.
Put 7 as the next digit of the answer. 
Result so far: 1267.0
Deduct 4795 from 5065 and we're left with 270.
Fetch the next digit (1) from the dividend, attach it to 270 and continue: 2701 / 685

On to step 7:
The number 685 fits into 2701 3 times, leaving a remainder of 646.
Use 3 as the next digit of our solution. 
Result so far: 12673.0
If we subtract 2055 from 2701, we get 646.
Fetch the next digit (0) from the dividend, attach it to 646 and continue: 6460 / 685

Advancing to step 8:
685 can be fit into 6460 9 times, resulting in a remainder of 295.
The number 9 becomes the next digit in our result. 
Result so far: 126739.0
The remainder is 295 after subtracting 6165 from 6460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Going ahead to step 9:
When dividing 2950 by 685, we get 4 with a remainder of 210.
The number 4 becomes the next digit in our result. 
Result so far: 126739.4
Subtracting 2740 from 2950 leaves us with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Let's proceed to step 10:
When dividing 2100 by 685, we get 3 with a remainder of 45.
Write down 3 as next digit of the result. 
Result so far: 126739.43
Subtracting 2055 from 2100 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 11:
The number 685 fits into 450 0 times, leaving a remainder of 450.
Write down 0 as next digit of the result. 
Result so far: 126739.43
Subtracting 0 from 450 leaves us with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Advancing to step 12:
When dividing 4500 by 685, we get 6 with a remainder of 390.
Write down 6 as next digit of the result. 
Result so far: 126739.4306
Subtract 4110 from 4500 to get 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Let's proceed to step 13:
If we divide 3900 by 685, we get 5 and a remainder of 475.
The next digit of our result is 5. 
Result so far: 126739.43065
Deduct 3425 from 3900 and we're left with 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

Advancing to step 14:
685 can be fit into 4750 6 times, resulting in a remainder of 640.
Use 6 as the next digit of our solution. 
Result so far: 126739.430656
If we take 4110 away from 4750, we end up with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Step 15:
When dividing 6400 by 685, we get 9 with a remainder of 235.
The number 9 becomes the next digit in our result. 
Result so far: 126739.4306569
Subtracting 6165 from 6400 leaves us with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Let's proceed to step 16:
The number 685 fits into 2350 3 times, leaving a remainder of 295.
Record the quotient 3 as the next digit in the result. 
Result so far: 126739.43065693
Deduct 2055 from 2350 and we're left with 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

The quotient of the division is 126739.43065693, and the remainder is 2.95e-07.
