Let's divide 623397 by 80
Our goal is to divide 623397 by 80.

Advancing to step 1:
6 divided by 80 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 80

On to step 2:
80 goes into 62 0 times with a remainder of 62.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 62 leaves us with 62.
Bring next digit (3) of the dividend behind the 62 and repeat the process: 623 / 80

Moving on to step 3:
If we divide 623 by 80, we get 7 and a remainder of 63.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 560 from 623, we get 63.
Grab the next digit (3) from the dividend, add it to 63, then carry on: 633 / 80

Step 4:
The number 80 fits into 633 7 times, leaving a remainder of 73.
Put 7 as the next digit of the answer. 
Result so far: 77.0
If we subtract 560 from 633, we get 73.
Include the next digit (9) from the dividend after 73, then repeat: 739 / 80

Going ahead to step 5:
The number 80 fits into 739 9 times, leaving a remainder of 19.
Use 9 as the next digit of our solution. 
Result so far: 779.0
The remainder is 19 after subtracting 720 from 739.
Fetch the next digit (7) from the dividend, attach it to 19 and continue: 197 / 80

Let's proceed to step 6:
80 can be fit into 197 2 times, resulting in a remainder of 37.
The number 2 becomes the next digit in our result. 
Result so far: 7792.0
Subtracting 160 from 197 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 7:
80 goes into 370 4 times with a remainder of 50.
Use 4 as the next digit of our solution. 
Result so far: 7792.4
Subtracting 320 from 370 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 8:
500 divided by 80 is 6 with a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 7792.46
If we take 480 away from 500, we end up 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.
Use 2 as the next digit of our solution. 
Result so far: 7792.462
If we subtract 160 from 200, we 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.

On to step 10:
If we divide 400 by 80, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 7792.4625
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.
Put 0 as the next digit of the answer. 
Result so far: 7792.4625
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.

Moving on to step 12:
80 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 7792.4625
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.

The final result is 7792.4625 with a remainder of 0.0.
