We divide 680446 by 80
We're looking to find how many times 80 goes into 680446.

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
Deduct 0 from 6 and we're left with 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 80

Advancing to step 2:
68 divided by 80 is 0 with a remainder of 68.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 68 to get 68.
Take the next digit (0) from the dividend and append it to 68, then repeat: 680 / 80

Advancing to step 3:
80 can be fit into 680 8 times, resulting in a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtract 640 from 680 to get 40.
Bring next digit (4) of the dividend behind the 40 and repeat the process: 404 / 80

Let's proceed to step 4:
The number 80 fits into 404 5 times, leaving a remainder of 4.
Write down 5 as next digit of the result. 
Result so far: 85.0
Deduct 400 from 404 and we're left with 4.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 80

Going ahead to step 5:
44 divided by 80 is 0 with a remainder of 44.
The number 0 becomes the next digit in our result. 
Result so far: 850.0
Deduct 0 from 44 and we're left with 44.
Append the next digit (6) from the dividend to 44 and continue with: 446 / 80

On to step 6:
If we divide 446 by 80, we get 5 and a remainder of 46.
The number 5 becomes the next digit in our result. 
Result so far: 8505.0
If we take 400 away from 446, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 7:
80 can be fit into 460 5 times, resulting in a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 8505.5
The remainder is 60 after subtracting 400 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 8:
If we divide 600 by 80, we get 7 and a remainder of 40.
Put 7 as the next digit of the answer. 
Result so far: 8505.57
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.

Let's proceed to step 9:
The number 80 fits into 400 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 8505.575
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 10:
80 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 8505.575
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.

Moving on to step 11:
80 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 8505.575
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.

The quotient of the division is 8505.575, and the remainder is 0.0.
