We look at the division of 438340 by 85 
Our goal is to divide 438340 by 85.

On to step 1:
The number 85 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 85

Moving on to step 2:
If we divide 43 by 85, we get 0 and a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Bring next digit (8) of the dividend behind the 43 and repeat the process: 438 / 85

Step 3:
When dividing 438 by 85, we get 5 with a remainder of 13.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 425 from 438, we get 13.
Fetch the next digit (3) from the dividend, attach it to 13 and continue: 133 / 85

Moving on to step 4:
85 can be fit into 133 1 times, resulting in a remainder of 48.
Write down 1 as next digit of the result. 
Result so far: 51.0
If we take 85 away from 133, we end up with 48.
Take the next digit (4) from the dividend and append it to 48, then repeat: 484 / 85

Step 5:
85 can be fit into 484 5 times, resulting in a remainder of 59.
Put 5 as the next digit of the answer. 
Result so far: 515.0
If we take 425 away from 484, we end up with 59.
Bring next digit (0) of the dividend behind the 59 and repeat the process: 590 / 85

Advancing to step 6:
85 goes into 590 6 times with a remainder of 80.
Use 6 as the next digit of our solution. 
Result so far: 5156.0
Deduct 510 from 590 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 7:
When dividing 800 by 85, we get 9 with a remainder of 35.
Write down 9 as next digit of the result. 
Result so far: 5156.9
If we take 765 away from 800, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 8:
85 can be fit into 350 4 times, resulting in a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 5156.94
Subtracting 340 from 350 leaves us with 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 9:
85 goes into 100 1 times with a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 5156.941
The remainder is 15 after subtracting 85 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 10:
When dividing 150 by 85, we get 1 with a remainder of 65.
Write down 1 as next digit of the result. 
Result so far: 5156.9411
Subtracting 85 from 150 leaves us 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.

After the division, we end up with 5156.9411 and a remainder of 0.00065.
