520494 ÷ 85 
Our goal is to divide 520494 by 85.

Step 1:
If we divide 5 by 85, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 85

On to step 2:
If we divide 52 by 85, we get 0 and a remainder of 52.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 52 leaves us with 52.
Grab the next digit (0) from the dividend, add it to 52, then carry on: 520 / 85

Moving on to step 3:
85 can be fit into 520 6 times, resulting in a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Deduct 510 from 520 and we're left with 10.
Fetch the next digit (4) from the dividend, attach it to 10 and continue: 104 / 85

Advancing to step 4:
If we divide 104 by 85, we get 1 and a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 61.0
Subtracting 85 from 104 leaves us with 19.
Bring next digit (9) of the dividend behind the 19 and repeat the process: 199 / 85

Going ahead to step 5:
If we divide 199 by 85, we get 2 and a remainder of 29.
Put 2 as the next digit of the answer. 
Result so far: 612.0
Subtract 170 from 199 to get 29.
Include the next digit (4) from the dividend after 29, then repeat: 294 / 85

On to step 6:
The number 85 fits into 294 3 times, leaving a remainder of 39.
Use 3 as the next digit of our solution. 
Result so far: 6123.0
If we take 255 away from 294, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 7:
390 divided by 85 is 4 with a remainder of 50.
Put 4 as the next digit of the answer. 
Result so far: 6123.4
Subtracting 340 from 390 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.

Step 8:
85 can be fit into 500 5 times, resulting in a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 6123.45
If we subtract 425 from 500, we 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.

Moving on to step 9:
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: 6123.458
If we take 680 away from 750, we end up 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.

Going ahead to step 10:
85 can be fit into 700 8 times, resulting in a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 6123.4588
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 result is 6123.4588 with a remainder of 0.0002.
