We look at the division of 438839 by 85 
We want to divide 438839 by 85.

On to step 1:
When dividing 4 by 85, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 85

Going ahead to step 2:
85 goes into 43 0 times with a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 43 and we're left with 43.
Append the next digit (8) from the dividend to 43 and continue with: 438 / 85

Going ahead to step 3:
When dividing 438 by 85, we get 5 with a remainder of 13.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 425 from 438, we get 13.
Fetch the next digit (8) from the dividend, attach it to 13 and continue: 138 / 85

Step 4:
The number 85 fits into 138 1 times, leaving a remainder of 53.
Put 1 as the next digit of the answer. 
Result so far: 51.0
The remainder is 53 after subtracting 85 from 138.
Fetch the next digit (3) from the dividend, attach it to 53 and continue: 533 / 85

Let's proceed to step 5:
If we divide 533 by 85, we get 6 and a remainder of 23.
The number 6 becomes the next digit in our result. 
Result so far: 516.0
If we subtract 510 from 533, we get 23.
Bring next digit (9) of the dividend behind the 23 and repeat the process: 239 / 85

Moving on to step 6:
85 can be fit into 239 2 times, resulting in a remainder of 69.
Use 2 as the next digit of our solution. 
Result so far: 5162.0
Subtracting 170 from 239 leaves us with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 7:
The number 85 fits into 690 8 times, leaving a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 5162.8
Subtract 680 from 690 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.

Moving on to step 8:
The number 85 fits into 100 1 times, leaving a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 5162.81
Deduct 85 from 100 and we're left 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.

Going ahead to step 9:
150 divided by 85 is 1 with a remainder of 65.
The next digit of our result is 1. 
Result so far: 5162.811
The remainder is 65 after subtracting 85 from 150.
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 outcome is 5162.811, with a leftover of 0.0065.
