We're dividing 338485 by 42 
We're looking to find how many times 42 goes into 338485.

Advancing to step 1:
When dividing 3 by 42, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 42

On to step 2:
42 can be fit into 33 0 times, resulting in a remainder of 33.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 33, we get 33.
Fetch the next digit (8) from the dividend, attach it to 33 and continue: 338 / 42

Let's proceed to step 3:
If we divide 338 by 42, we get 8 and a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 336 from 338 to get 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 42

On to step 4:
42 goes into 24 0 times with a remainder of 24.
Write down 0 as next digit of the result. 
Result so far: 80.0
Subtracting 0 from 24 leaves us with 24.
Grab the next digit (8) from the dividend, add it to 24, then carry on: 248 / 42

Moving on to step 5:
The number 42 fits into 248 5 times, leaving a remainder of 38.
Put 5 as the next digit of the answer. 
Result so far: 805.0
Subtract 210 from 248 to get 38.
Bring next digit (5) of the dividend behind the 38 and repeat the process: 385 / 42

Let's proceed to step 6:
If we divide 385 by 42, we get 9 and a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 8059.0
If we subtract 378 from 385, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
42 goes into 70 1 times with a remainder of 28.
Use 1 as the next digit of our solution. 
Result so far: 8059.1
The remainder is 28 after subtracting 42 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 8:
If we divide 280 by 42, we get 6 and a remainder of 28.
Use 6 as the next digit of our solution. 
Result so far: 8059.16
If we take 252 away from 280, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 9:
If we divide 280 by 42, we get 6 and a remainder of 28.
The next digit of our result is 6. 
Result so far: 8059.166
The remainder is 28 after subtracting 252 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final result is 8059.166 with a remainder of 0.0028.
