We're dividing 686304 by 85 
We're looking to find how many times 85 goes into 686304.

Let's proceed to step 1:
When dividing 6 by 85, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 85

On to step 2:
When dividing 68 by 85, we get 0 with a remainder of 68.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 68 and we're left with 68.
Bring next digit (6) of the dividend behind the 68 and repeat the process: 686 / 85

Step 3:
85 goes into 686 8 times with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 680 away from 686, we end up with 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 85

Let's proceed to step 4:
If we divide 63 by 85, we get 0 and a remainder of 63.
Record the quotient 0 as the next digit in the result. 
Result so far: 80.0
Subtract 0 from 63 to get 63.
Take the next digit (0) from the dividend and append it to 63, then repeat: 630 / 85

Let's proceed to step 5:
85 can be fit into 630 7 times, resulting in a remainder of 35.
Use 7 as the next digit of our solution. 
Result so far: 807.0
Subtracting 595 from 630 leaves us with 35.
Append the next digit (4) from the dividend to 35 and continue with: 354 / 85

On to step 6:
The number 85 fits into 354 4 times, leaving a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 8074.0
Deduct 340 from 354 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 7:
85 goes into 140 1 times with a remainder of 55.
Record the quotient 1 as the next digit in the result. 
Result so far: 8074.1
The remainder is 55 after subtracting 85 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 8:
When dividing 550 by 85, we get 6 with a remainder of 40.
The number 6 becomes the next digit in our result. 
Result so far: 8074.16
Subtract 510 from 550 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 9:
When dividing 400 by 85, we get 4 with a remainder of 60.
Use 4 as the next digit of our solution. 
Result so far: 8074.164
If we take 340 away from 400, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 10:
If we divide 600 by 85, we get 7 and a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 8074.1647
Subtract 595 from 600 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 11:
The number 85 fits into 50 0 times, leaving a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 8074.1647
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 12:
The number 85 fits into 500 5 times, leaving a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 8074.164705
Subtract 425 from 500 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 13:
750 divided by 85 is 8 with a remainder of 70.
The next digit of our result is 8. 
Result so far: 8074.1647058
The remainder is 70 after subtracting 680 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 14:
85 goes into 700 8 times with a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 8074.16470588
Deduct 680 from 700 and we're left 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 outcome is 8074.16470588, with a leftover of 2e-08.
