We look at the division of 42342 by 85 
Let's see how many times 85 fits into 42342.

Moving on to step 1:
The number 85 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 85

Let's proceed to step 2:
85 goes into 42 0 times with a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Bring next digit (3) of the dividend behind the 42 and repeat the process: 423 / 85

Going ahead to step 3:
The number 85 fits into 423 4 times, leaving a remainder of 83.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 340 away from 423, we end up with 83.
Take the next digit (4) from the dividend and append it to 83, then repeat: 834 / 85

Advancing to step 4:
85 goes into 834 9 times with a remainder of 69.
Use 9 as the next digit of our solution. 
Result so far: 49.0
Subtract 765 from 834 to get 69.
Fetch the next digit (2) from the dividend, attach it to 69 and continue: 692 / 85

Advancing to step 5:
85 can be fit into 692 8 times, resulting in a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 498.0
Subtract 680 from 692 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 6:
85 can be fit into 120 1 times, resulting in a remainder of 35.
The next digit of our result is 1. 
Result so far: 498.1
The remainder is 35 after subtracting 85 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 7:
The number 85 fits into 350 4 times, leaving a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 498.14
Subtract 340 from 350 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.

Step 8:
The number 85 fits into 100 1 times, leaving a remainder of 15.
The next digit of our result is 1. 
Result so far: 498.141
If we take 85 away from 100, we end up 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.

Let's proceed to step 9:
When dividing 150 by 85, we get 1 with a remainder of 65.
Put 1 as the next digit of the answer. 
Result so far: 498.1411
Deduct 85 from 150 and we're left 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.

The final result is 498.1411 with a remainder of 0.00065.
