850415 divided by 80 
Our goal is to divide 850415 by 80.

On to step 1:
80 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 80

Step 2:
When dividing 85 by 80, we get 1 with a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 80 away from 85, we end up with 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 80

On to step 3:
50 divided by 80 is 0 with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtract 0 from 50 to get 50.
Fetch the next digit (4) from the dividend, attach it to 50 and continue: 504 / 80

Step 4:
80 goes into 504 6 times with a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 106.0
Subtract 480 from 504 to get 24.
Fetch the next digit (1) from the dividend, attach it to 24 and continue: 241 / 80

Step 5:
When dividing 241 by 80, we get 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 1063.0
If we take 240 away from 241, we end up with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 80

Advancing to step 6:
The number 80 fits into 15 0 times, leaving a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 10630.0
Subtracting 0 from 15 leaves us 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.

Let's proceed to step 7:
80 goes into 150 1 times with a remainder of 70.
Put 1 as the next digit of the answer. 
Result so far: 10630.1
If we subtract 80 from 150, we 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.

Step 8:
When dividing 700 by 80, we get 8 with a remainder of 60.
Write down 8 as next digit of the result. 
Result so far: 10630.18
If we take 640 away from 700, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 9:
If we divide 600 by 80, we get 7 and a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 10630.187
Deduct 560 from 600 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
When dividing 400 by 80, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 10630.1875
The remainder is 0 after subtracting 400 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 11:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10630.1875
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.

Let's proceed to step 12:
If we divide 0 by 80, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 10630.1875
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.

Our division results in 10630.1875 with a remaining 0.0.
