We divide 623408 by 80
We want to divide 623408 by 80.

Going ahead to step 1:
The number 80 fits into 6 0 times, leaving 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

Moving on to step 2:
80 goes into 62 0 times with a remainder of 62.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 62 after subtracting 0 from 62.
Bring next digit (3) of the dividend behind the 62 and repeat the process: 623 / 80

Moving on to step 3:
80 can be fit into 623 7 times, resulting in a remainder of 63.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 560 from 623, we get 63.
Fetch the next digit (4) from the dividend, attach it to 63 and continue: 634 / 80

Step 4:
If we divide 634 by 80, we get 7 and a remainder of 74.
Write down 7 as next digit of the result. 
Result so far: 77.0
Subtract 560 from 634 to get 74.
Append the next digit (0) from the dividend to 74 and continue with: 740 / 80

Let's proceed to step 5:
80 can be fit into 740 9 times, resulting in a remainder of 20.
Use 9 as the next digit of our solution. 
Result so far: 779.0
Deduct 720 from 740 and we're left with 20.
Include the next digit (8) from the dividend after 20, then repeat: 208 / 80

Going ahead to step 6:
The number 80 fits into 208 2 times, leaving a remainder of 48.
The next digit of our result is 2. 
Result so far: 7792.0
Deduct 160 from 208 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 7:
If we divide 480 by 80, we get 6 and a remainder of 0.
The next digit of our result is 6. 
Result so far: 7792.6
If we take 480 away from 480, 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.

Step 8:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 7792.6
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.

Going ahead to step 9:
80 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 7792.6
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.

After the division, we end up with 7792.6 and a remainder of 0.0.
