Let's divide 415999 by 80
We want to figure out the number of times 415999 can be divided by 80.

Let's proceed to step 1:
The number 80 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 80

Advancing to step 2:
80 can be fit into 41 0 times, resulting in a remainder of 41.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 41 after subtracting 0 from 41.
Append the next digit (5) from the dividend to 41 and continue with: 415 / 80

Advancing to step 3:
When dividing 415 by 80, we get 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 15 after subtracting 400 from 415.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 80

Let's proceed to step 4:
If we divide 159 by 80, we get 1 and a remainder of 79.
The number 1 becomes the next digit in our result. 
Result so far: 51.0
Subtract 80 from 159 to get 79.
Grab the next digit (9) from the dividend, add it to 79, then carry on: 799 / 80

On to step 5:
80 goes into 799 9 times with a remainder of 79.
Write down 9 as next digit of the result. 
Result so far: 519.0
Deduct 720 from 799 and we're left with 79.
Fetch the next digit (9) from the dividend, attach it to 79 and continue: 799 / 80

Let's proceed to step 6:
If we divide 799 by 80, we get 9 and a remainder of 79.
Write down 9 as next digit of the result. 
Result so far: 5199.0
If we subtract 720 from 799, we get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Moving on to step 7:
When dividing 790 by 80, we get 9 with a remainder of 70.
The next digit of our result is 9. 
Result so far: 5199.9
Deduct 720 from 790 and we're left 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 8:
80 can be fit into 700 8 times, resulting in a remainder of 60.
Record the quotient 8 as the next digit in the result. 
Result so far: 5199.98
The remainder is 60 after subtracting 640 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 9:
When dividing 600 by 80, we get 7 with a remainder of 40.
The number 7 becomes the next digit in our result. 
Result so far: 5199.987
The remainder is 40 after subtracting 560 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 10:
When dividing 400 by 80, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 5199.9875
If we take 400 away from 400, 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.

Let's proceed to step 11:
80 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 5199.9875
If we subtract 0 from 0, 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.

Advancing to step 12:
80 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 5199.9875
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.

After the division, we end up with 5199.9875 and a remainder of 0.0.
