Let's divide 686355 by 85
We're looking to find how many times 85 goes into 686355.

Advancing to step 1:
85 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 85

Step 2:
68 divided by 85 is 0 with a remainder of 68.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 68 and we're left with 68.
Append the next digit (6) from the dividend to 68 and continue with: 686 / 85

Moving on to step 3:
When dividing 686 by 85, we get 8 with a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 680 from 686 leaves us with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 85

Let's proceed to step 4:
If we divide 63 by 85, we get 0 and a remainder of 63.
Use 0 as the next digit of our solution. 
Result so far: 80.0
Subtract 0 from 63 to get 63.
Include the next digit (5) from the dividend after 63, then repeat: 635 / 85

Step 5:
85 can be fit into 635 7 times, resulting in a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 807.0
Deduct 595 from 635 and we're left with 40.
Bring next digit (5) of the dividend behind the 40 and repeat the process: 405 / 85

Going ahead to step 6:
405 divided by 85 is 4 with a remainder of 65.
Put 4 as the next digit of the answer. 
Result so far: 8074.0
If we take 340 away from 405, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 7:
650 divided by 85 is 7 with a remainder of 55.
Record the quotient 7 as the next digit in the result. 
Result so far: 8074.7
Subtracting 595 from 650 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 8:
85 can be fit into 550 6 times, resulting in a remainder of 40.
The number 6 becomes the next digit in our result. 
Result so far: 8074.76
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.

Advancing to step 9:
85 goes into 400 4 times with a remainder of 60.
Write down 4 as next digit of the result. 
Result so far: 8074.764
Deduct 340 from 400 and we're left 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.

Advancing to step 10:
If we divide 600 by 85, we get 7 and a remainder of 5.
The next digit of our result is 7. 
Result so far: 8074.7647
If we subtract 595 from 600, we 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.

Advancing to step 11:
50 divided by 85 is 0 with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 8074.7647
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 12:
The number 85 fits into 500 5 times, leaving a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 8074.764705
Subtracting 425 from 500 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 13:
The number 85 fits into 750 8 times, leaving a remainder of 70.
Record the quotient 8 as the next digit in the result. 
Result so far: 8074.7647058
Subtracting 680 from 750 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 14:
85 can be fit into 700 8 times, resulting in a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 8074.76470588
Subtract 680 from 700 to get 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 8074.76470588 with a remainder of 2e-08.
