We divide 622404 by 80
We're looking to find how many times 80 goes into 622404.

On to step 1:
When dividing 6 by 80, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 80

Going ahead to step 2:
The number 80 fits into 62 0 times, leaving a remainder of 62.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 62 to get 62.
Fetch the next digit (2) from the dividend, attach it to 62 and continue: 622 / 80

Going ahead to step 3:
80 can be fit into 622 7 times, resulting in a remainder of 62.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 560 from 622 and we're left with 62.
Fetch the next digit (4) from the dividend, attach it to 62 and continue: 624 / 80

Advancing to step 4:
The number 80 fits into 624 7 times, leaving a remainder of 64.
Use 7 as the next digit of our solution. 
Result so far: 77.0
If we subtract 560 from 624, we get 64.
Include the next digit (0) from the dividend after 64, then repeat: 640 / 80

Advancing to step 5:
When dividing 640 by 80, we get 8 with a remainder of 0.
The next digit of our result is 8. 
Result so far: 778.0
If we subtract 640 from 640, we get 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 80

On to step 6:
If we divide 4 by 80, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 7780.0
Subtract 0 from 4 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
40 divided by 80 is 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 7780.0
Deduct 0 from 40 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.

On to step 8:
400 divided by 80 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 7780.05
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.

Moving on to step 9:
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: 7780.05
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.

Moving on to step 10:
When dividing 0 by 80, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 7780.05
Deduct 0 from 0 and we're left 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 7780.05 with a remainder of 0.0.
