We look at the division of 819835 by 42 
Our goal is to divide 819835 by 42.

Let's proceed to step 1:
8 divided by 42 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 42

Let's proceed to step 2:
81 divided by 42 is 1 with a remainder of 39.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 39 after subtracting 42 from 81.
Append the next digit (9) from the dividend to 39 and continue with: 399 / 42

Step 3:
42 goes into 399 9 times with a remainder of 21.
Write down 9 as next digit of the result. 
Result so far: 19.0
The remainder is 21 after subtracting 378 from 399.
Fetch the next digit (8) from the dividend, attach it to 21 and continue: 218 / 42

Let's proceed to step 4:
42 goes into 218 5 times with a remainder of 8.
The number 5 becomes the next digit in our result. 
Result so far: 195.0
Deduct 210 from 218 and we're left with 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 42

On to step 5:
If we divide 83 by 42, we get 1 and a remainder of 41.
Use 1 as the next digit of our solution. 
Result so far: 1951.0
Subtract 42 from 83 to get 41.
Include the next digit (5) from the dividend after 41, then repeat: 415 / 42

Step 6:
If we divide 415 by 42, we get 9 and a remainder of 37.
Record the quotient 9 as the next digit in the result. 
Result so far: 19519.0
If we subtract 378 from 415, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 7:
When dividing 370 by 42, we get 8 with a remainder of 34.
The number 8 becomes the next digit in our result. 
Result so far: 19519.8
If we subtract 336 from 370, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 8:
The number 42 fits into 340 8 times, leaving a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 19519.88
If we take 336 away from 340, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 19519.88 with a remaining 0.004.
