We look at the division of 505173 by 85 
We want to divide 505173 by 85.

Advancing to step 1:
When dividing 5 by 85, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 85

Advancing to step 2:
85 goes into 50 0 times with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 50 to get 50.
Include the next digit (5) from the dividend after 50, then repeat: 505 / 85

Moving on to step 3:
85 can be fit into 505 5 times, resulting in a remainder of 80.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 425 from 505 to get 80.
Fetch the next digit (1) from the dividend, attach it to 80 and continue: 801 / 85

Moving on to step 4:
The number 85 fits into 801 9 times, leaving a remainder of 36.
The next digit of our result is 9. 
Result so far: 59.0
Subtract 765 from 801 to get 36.
Bring next digit (7) of the dividend behind the 36 and repeat the process: 367 / 85

Let's proceed to step 5:
The number 85 fits into 367 4 times, leaving a remainder of 27.
Put 4 as the next digit of the answer. 
Result so far: 594.0
Deduct 340 from 367 and we're left with 27.
Fetch the next digit (3) from the dividend, attach it to 27 and continue: 273 / 85

On to step 6:
If we divide 273 by 85, we get 3 and a remainder of 18.
Put 3 as the next digit of the answer. 
Result so far: 5943.0
Subtracting 255 from 273 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 7:
The number 85 fits into 180 2 times, leaving a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 5943.2
Subtract 170 from 180 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
When dividing 100 by 85, we get 1 with a remainder of 15.
The next digit of our result is 1. 
Result so far: 5943.21
Subtracting 85 from 100 leaves us with 15.
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 9:
The number 85 fits into 150 1 times, leaving a remainder of 65.
The next digit of our result is 1. 
Result so far: 5943.211
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.

After the division, we end up with 5943.211 and a remainder of 0.0065.
