We divide 850500 by 42
We're looking to find how many times 42 goes into 850500.

On to step 1:
When dividing 8 by 42, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 42

On to step 2:
85 divided by 42 is 2 with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 84 away from 85, we end up with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 42

Let's proceed to step 3:
42 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
If we take 0 away from 10, we end up with 10.
Include the next digit (5) from the dividend after 10, then repeat: 105 / 42

On to step 4:
If we divide 105 by 42, we get 2 and a remainder of 21.
Use 2 as the next digit of our solution. 
Result so far: 202.0
If we subtract 84 from 105, we get 21.
Fetch the next digit (0) from the dividend, attach it to 21 and continue: 210 / 42

Step 5:
When dividing 210 by 42, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 2025.0
Deduct 210 from 210 and we're left with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 42

Advancing to step 6:
If we divide 0 by 42, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 20250.0
Subtracting 0 from 0 leaves us 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.

On to step 7:
0 divided by 42 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 20250.0
If we subtract 0 from 0, we 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.

Advancing to step 8:
The number 42 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 20250.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 20250.0 with a balance of 0.0.
