We divide 406815 by 85
We want to divide 406815 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
Subtract 0 from 4 to get 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 85

On to step 2:
85 can be fit into 40 0 times, resulting in a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Bring next digit (6) of the dividend behind the 40 and repeat the process: 406 / 85

Going ahead to step 3:
If we divide 406 by 85, we get 4 and a remainder of 66.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 66 after subtracting 340 from 406.
Take the next digit (8) from the dividend and append it to 66, then repeat: 668 / 85

Advancing to step 4:
668 divided by 85 is 7 with a remainder of 73.
Write down 7 as next digit of the result. 
Result so far: 47.0
Subtracting 595 from 668 leaves us with 73.
Grab the next digit (1) from the dividend, add it to 73, then carry on: 731 / 85

Step 5:
If we divide 731 by 85, we get 8 and a remainder of 51.
Use 8 as the next digit of our solution. 
Result so far: 478.0
If we take 680 away from 731, we end up with 51.
Fetch the next digit (5) from the dividend, attach it to 51 and continue: 515 / 85

Step 6:
When dividing 515 by 85, we get 6 with a remainder of 5.
Put 6 as the next digit of the answer. 
Result so far: 4786.0
Subtracting 510 from 515 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 7:
85 can be fit into 50 0 times, resulting in a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 4786.0
Deduct 0 from 50 and we're left 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.

Step 8:
When dividing 500 by 85, we get 5 with a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 4786.05
If we subtract 425 from 500, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 9:
The number 85 fits into 750 8 times, leaving a remainder of 70.
The next digit of our result is 8. 
Result so far: 4786.058
Subtract 680 from 750 to get 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 10:
85 goes into 700 8 times with a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 4786.0588
Subtracting 680 from 700 leaves us with 20.
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 4786.0588, and the remainder is 0.0002.
