We're dividing 850524 by 12 
Let's see how many times 12 fits into 850524.

On to step 1:
If we divide 8 by 12, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 12

On to step 2:
If we divide 85 by 12, we get 7 and a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 7.0
The remainder is 1 after subtracting 84 from 85.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 12

Step 3:
12 goes into 10 0 times with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 70.0
Subtract 0 from 10 to get 10.
Include the next digit (5) from the dividend after 10, then repeat: 105 / 12

Moving on to step 4:
105 divided by 12 is 8 with a remainder of 9.
Put 8 as the next digit of the answer. 
Result so far: 708.0
Subtract 96 from 105 to get 9.
Grab the next digit (2) from the dividend, add it to 9, then carry on: 92 / 12

Going ahead to step 5:
12 can be fit into 92 7 times, resulting in a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 7087.0
If we take 84 away from 92, we end up with 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 12

Let's proceed to step 6:
When dividing 84 by 12, we get 7 with a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 70877.0
Deduct 84 from 84 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 7:
If we divide 0 by 12, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 70877.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
If we divide 0 by 12, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 70877.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 70877.0, and the remainder is 0.0.
