We're dividing 394025 by 85 
Our goal is to divide 394025 by 85.

Step 1:
85 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 85

Let's proceed to step 2:
The number 85 fits into 39 0 times, leaving a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Take the next digit (4) from the dividend and append it to 39, then repeat: 394 / 85

Step 3:
85 goes into 394 4 times with a remainder of 54.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 340 from 394 to get 54.
Fetch the next digit (0) from the dividend, attach it to 54 and continue: 540 / 85

Advancing to step 4:
The number 85 fits into 540 6 times, leaving a remainder of 30.
Use 6 as the next digit of our solution. 
Result so far: 46.0
The remainder is 30 after subtracting 510 from 540.
Grab the next digit (2) from the dividend, add it to 30, then carry on: 302 / 85

Advancing to step 5:
85 goes into 302 3 times with a remainder of 47.
Record the quotient 3 as the next digit in the result. 
Result so far: 463.0
If we subtract 255 from 302, we get 47.
Bring next digit (5) of the dividend behind the 47 and repeat the process: 475 / 85

On to step 6:
85 can be fit into 475 5 times, resulting in a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 4635.0
Subtracting 425 from 475 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 7:
If we divide 500 by 85, we get 5 and a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 4635.5
The remainder is 75 after subtracting 425 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 8:
If we divide 750 by 85, we get 8 and a remainder of 70.
The number 8 becomes the next digit in our result. 
Result so far: 4635.58
Subtracting 680 from 750 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 9:
If we divide 700 by 85, we get 8 and a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 4635.588
The remainder is 20 after subtracting 680 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The quotient of the division is 4635.588, and the remainder is 0.002.
