We look at the division of 905212 by 85 
Our goal is to divide 905212 by 85.

Going ahead to step 1:
The number 85 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 85

Let's proceed to step 2:
90 divided by 85 is 1 with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 85 away from 90, we end up with 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 85

Moving on to step 3:
85 can be fit into 55 0 times, resulting in a remainder of 55.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtract 0 from 55 to get 55.
Include the next digit (2) from the dividend after 55, then repeat: 552 / 85

Step 4:
552 divided by 85 is 6 with a remainder of 42.
The next digit of our result is 6. 
Result so far: 106.0
If we subtract 510 from 552, we get 42.
Append the next digit (1) from the dividend to 42 and continue with: 421 / 85

Let's proceed to step 5:
85 can be fit into 421 4 times, resulting in a remainder of 81.
The number 4 becomes the next digit in our result. 
Result so far: 1064.0
If we subtract 340 from 421, we get 81.
Take the next digit (2) from the dividend and append it to 81, then repeat: 812 / 85

On to step 6:
85 goes into 812 9 times with a remainder of 47.
The number 9 becomes the next digit in our result. 
Result so far: 10649.0
If we take 765 away from 812, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 7:
85 goes into 470 5 times with a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 10649.5
If we subtract 425 from 470, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 8:
If we divide 450 by 85, we get 5 and a remainder of 25.
The next digit of our result is 5. 
Result so far: 10649.55
If we subtract 425 from 450, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The final result is 10649.55 with a remainder of 0.025.
