422887 ÷ 80 
We want to figure out the number of times 422887 can be divided by 80.

Let's proceed to step 1:
If we divide 4 by 80, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 80

Step 2:
The number 80 fits into 42 0 times, leaving a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Append the next digit (2) from the dividend to 42 and continue with: 422 / 80

Advancing to step 3:
80 can be fit into 422 5 times, resulting in a remainder of 22.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we subtract 400 from 422, we get 22.
Bring next digit (8) of the dividend behind the 22 and repeat the process: 228 / 80

Let's proceed to step 4:
The number 80 fits into 228 2 times, leaving a remainder of 68.
Use 2 as the next digit of our solution. 
Result so far: 52.0
Subtracting 160 from 228 leaves us with 68.
Bring next digit (8) of the dividend behind the 68 and repeat the process: 688 / 80

Going ahead to step 5:
When dividing 688 by 80, we get 8 with a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 528.0
The remainder is 48 after subtracting 640 from 688.
Include the next digit (7) from the dividend after 48, then repeat: 487 / 80

On to step 6:
The number 80 fits into 487 6 times, leaving a remainder of 7.
Record the quotient 6 as the next digit in the result. 
Result so far: 5286.0
If we take 480 away from 487, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
When dividing 70 by 80, we get 0 with a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 5286.0
Subtracting 0 from 70 leaves us 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.

Moving on to step 8:
80 goes into 700 8 times with a remainder of 60.
The number 8 becomes the next digit in our result. 
Result so far: 5286.08
Deduct 640 from 700 and we're left 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.

Step 9:
80 goes into 600 7 times with a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 5286.087
Subtracting 560 from 600 leaves us 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:
80 can be fit into 400 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 5286.0875
Subtract 400 from 400 to 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 11:
If we divide 0 by 80, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 5286.0875
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.

Step 12:
When dividing 0 by 80, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 5286.0875
Subtract 0 from 0 to 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.

After the division, we end up with 5286.0875 and a remainder of 0.0.
