We're dividing 405085 by 80 
Our goal is to divide 405085 by 80.

Let's proceed to step 1:
The number 80 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 80

Advancing to step 2:
80 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
If we subtract 0 from 40, we get 40.
Append the next digit (5) from the dividend to 40 and continue with: 405 / 80

On to step 3:
When dividing 405 by 80, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 400 from 405 and we're left with 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 80

Going ahead to step 4:
If we divide 50 by 80, we get 0 and a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 50.0
If we take 0 away from 50, we end up with 50.
Append the next digit (8) from the dividend to 50 and continue with: 508 / 80

Moving on to step 5:
If we divide 508 by 80, we get 6 and a remainder of 28.
Write down 6 as next digit of the result. 
Result so far: 506.0
If we take 480 away from 508, we end up with 28.
Bring next digit (5) of the dividend behind the 28 and repeat the process: 285 / 80

Moving on to step 6:
285 divided by 80 is 3 with a remainder of 45.
Write down 3 as next digit of the result. 
Result so far: 5063.0
If we subtract 240 from 285, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 7:
When dividing 450 by 80, we get 5 with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 5063.5
Subtract 400 from 450 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 8:
The number 80 fits into 500 6 times, leaving a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 5063.56
Subtracting 480 from 500 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.

Advancing to step 9:
80 goes into 200 2 times with a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 5063.562
Subtract 160 from 200 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 10:
If we divide 400 by 80, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 5063.5625
If we subtract 400 from 400, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 11:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 5063.5625
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 12:
0 divided by 80 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 5063.5625
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 5063.5625 with a remaining 0.0.
