We look at the division of 665099 by 85 
We're looking to find how many times 85 goes into 665099.

Going ahead to step 1:
85 goes into 6 0 times with 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 (6) from the dividend after 6, then repeat: 66 / 85

Moving on to step 2:
If we divide 66 by 85, we get 0 and a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Bring next digit (5) of the dividend behind the 66 and repeat the process: 665 / 85

Moving on to step 3:
85 goes into 665 7 times with a remainder of 70.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 595 away from 665, we end up with 70.
Grab the next digit (0) from the dividend, add it to 70, then carry on: 700 / 85

Going ahead to step 4:
If we divide 700 by 85, we get 8 and a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 78.0
Subtract 680 from 700 to get 20.
Fetch the next digit (9) from the dividend, attach it to 20 and continue: 209 / 85

Moving on to step 5:
If we divide 209 by 85, we get 2 and a remainder of 39.
Use 2 as the next digit of our solution. 
Result so far: 782.0
If we subtract 170 from 209, we get 39.
Append the next digit (9) from the dividend to 39 and continue with: 399 / 85

Step 6:
85 can be fit into 399 4 times, resulting in a remainder of 59.
The number 4 becomes the next digit in our result. 
Result so far: 7824.0
If we subtract 340 from 399, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 7:
85 can be fit into 590 6 times, resulting in a remainder of 80.
The next digit of our result is 6. 
Result so far: 7824.6
Subtract 510 from 590 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 8:
85 goes into 800 9 times with a remainder of 35.
Write down 9 as next digit of the result. 
Result so far: 7824.69
If we subtract 765 from 800, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 9:
When dividing 350 by 85, we get 4 with a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 7824.694
If we take 340 away from 350, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 10:
The number 85 fits into 100 1 times, leaving a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 7824.6941
The remainder is 15 after subtracting 85 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 11:
150 divided by 85 is 1 with a remainder of 65.
Put 1 as the next digit of the answer. 
Result so far: 7824.69411
Subtracting 85 from 150 leaves us 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.

The final result is 7824.69411 with a remainder of 6.5e-05.
