We're dividing 422491 by 80 
Our goal is to divide 422491 by 80.

Advancing to step 1:
The number 80 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 80

On to step 2:
80 goes into 42 0 times with a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Grab the next digit (2) from the dividend, add it to 42, then carry on: 422 / 80

On to step 3:
422 divided by 80 is 5 with a remainder of 22.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 400 from 422 to get 22.
Include the next digit (4) from the dividend after 22, then repeat: 224 / 80

Step 4:
When dividing 224 by 80, we get 2 with a remainder of 64.
Record the quotient 2 as the next digit in the result. 
Result so far: 52.0
Subtracting 160 from 224 leaves us with 64.
Take the next digit (9) from the dividend and append it to 64, then repeat: 649 / 80

Advancing to step 5:
The number 80 fits into 649 8 times, leaving a remainder of 9.
Put 8 as the next digit of the answer. 
Result so far: 528.0
The remainder is 9 after subtracting 640 from 649.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 80

Moving on to step 6:
80 can be fit into 91 1 times, resulting in a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 5281.0
Subtracting 80 from 91 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 7:
80 can be fit into 110 1 times, resulting in a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 5281.1
If we take 80 away from 110, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
300 divided by 80 is 3 with a remainder of 60.
Put 3 as the next digit of the answer. 
Result so far: 5281.13
Deduct 240 from 300 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.

Let's proceed to step 9:
80 goes into 600 7 times with a remainder of 40.
The number 7 becomes the next digit in our result. 
Result so far: 5281.137
If we take 560 away from 600, we end up 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.

Moving on to step 10:
400 divided by 80 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 5281.1375
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.

Let's proceed to step 11:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 5281.1375
Subtracting 0 from 0 leaves us 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.

Moving on to step 12:
If we divide 0 by 80, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 5281.1375
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 5281.1375 with a remaining 0.0.
