673479 ÷ 80 
We're looking to find how many times 80 goes into 673479.

Going ahead to step 1:
When dividing 6 by 80, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 80

Step 2:
80 can be fit into 67 0 times, resulting in a remainder of 67.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 67, we get 67.
Bring next digit (3) of the dividend behind the 67 and repeat the process: 673 / 80

Step 3:
When dividing 673 by 80, we get 8 with a remainder of 33.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 640 from 673 and we're left with 33.
Include the next digit (4) from the dividend after 33, then repeat: 334 / 80

Step 4:
80 can be fit into 334 4 times, resulting in a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 84.0
Deduct 320 from 334 and we're left with 14.
Append the next digit (7) from the dividend to 14 and continue with: 147 / 80

Going ahead to step 5:
If we divide 147 by 80, we get 1 and a remainder of 67.
Use 1 as the next digit of our solution. 
Result so far: 841.0
Deduct 80 from 147 and we're left with 67.
Fetch the next digit (9) from the dividend, attach it to 67 and continue: 679 / 80

Moving on to step 6:
80 goes into 679 8 times with a remainder of 39.
Record the quotient 8 as the next digit in the result. 
Result so far: 8418.0
Subtracting 640 from 679 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 7:
390 divided by 80 is 4 with a remainder of 70.
Use 4 as the next digit of our solution. 
Result so far: 8418.4
If we take 320 away from 390, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 8:
80 goes into 700 8 times with a remainder of 60.
Write down 8 as next digit of the result. 
Result so far: 8418.48
The remainder is 60 after subtracting 640 from 700.
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 9:
If we divide 600 by 80, we get 7 and a remainder of 40.
The next digit of our result is 7. 
Result so far: 8418.487
Subtracting 560 from 600 leaves us 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.

Going ahead to step 10:
80 can be fit into 400 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 8418.4875
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.

Step 11:
80 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 8418.4875
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.

Going ahead to step 12:
80 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 8418.4875
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.

In conclusion, the division gives 8418.4875 with a balance of 0.0.
