Let's divide 663814 by 85
We're looking to find how many times 85 goes into 663814.

Moving on to step 1:
If we divide 6 by 85, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 85

Let's proceed to step 2:
85 goes into 66 0 times with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Grab the next digit (3) from the dividend, add it to 66, then carry on: 663 / 85

On to step 3:
85 can be fit into 663 7 times, resulting in a remainder of 68.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 595 from 663, we get 68.
Include the next digit (8) from the dividend after 68, then repeat: 688 / 85

Let's proceed to step 4:
If we divide 688 by 85, we get 8 and a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 78.0
Subtract 680 from 688 to get 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 85

Going ahead to step 5:
85 goes into 81 0 times with a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 780.0
If we take 0 away from 81, we end up with 81.
Append the next digit (4) from the dividend to 81 and continue with: 814 / 85

Moving on to step 6:
If we divide 814 by 85, we get 9 and a remainder of 49.
The next digit of our result is 9. 
Result so far: 7809.0
Deduct 765 from 814 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 7:
When dividing 490 by 85, we get 5 with a remainder of 65.
Use 5 as the next digit of our solution. 
Result so far: 7809.5
Subtracting 425 from 490 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.

Moving on to step 8:
When dividing 650 by 85, we get 7 with a remainder of 55.
Put 7 as the next digit of the answer. 
Result so far: 7809.57
The remainder is 55 after subtracting 595 from 650.
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 9:
85 can be fit into 550 6 times, resulting in a remainder of 40.
The next digit of our result is 6. 
Result so far: 7809.576
If we subtract 510 from 550, we 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 10:
400 divided by 85 is 4 with a remainder of 60.
The number 4 becomes the next digit in our result. 
Result so far: 7809.5764
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.

Let's proceed to step 11:
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: 7809.57647
The remainder is 5 after subtracting 595 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 12:
85 goes into 50 0 times with a remainder of 50.
The next digit of our result is 0. 
Result so far: 7809.57647
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 13:
When dividing 500 by 85, we get 5 with a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 7809.5764705
Deduct 425 from 500 and we're left 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.

Advancing to step 14:
The number 85 fits into 750 8 times, leaving a remainder of 70.
The number 8 becomes the next digit in our result. 
Result so far: 7809.57647058
Subtract 680 from 750 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final outcome is 7809.57647058, with a leftover of 7e-08.
