673747 ÷ 80 
We're looking to find how many times 80 goes into 673747.

Moving on to step 1:
6 divided by 80 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 80

Moving on to step 2:
67 divided by 80 is 0 with a remainder of 67.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 67 to get 67.
Bring next digit (3) of the dividend behind the 67 and repeat the process: 673 / 80

Moving on to step 3:
673 divided by 80 is 8 with a remainder of 33.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Deduct 640 from 673 and we're left with 33.
Bring next digit (7) of the dividend behind the 33 and repeat the process: 337 / 80

Step 4:
80 can be fit into 337 4 times, resulting in a remainder of 17.
The number 4 becomes the next digit in our result. 
Result so far: 84.0
The remainder is 17 after subtracting 320 from 337.
Include the next digit (4) from the dividend after 17, then repeat: 174 / 80

Advancing to step 5:
When dividing 174 by 80, we get 2 with a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 842.0
The remainder is 14 after subtracting 160 from 174.
Bring next digit (7) of the dividend behind the 14 and repeat the process: 147 / 80

On to step 6:
The number 80 fits into 147 1 times, leaving a remainder of 67.
Write down 1 as next digit of the result. 
Result so far: 8421.0
Subtracting 80 from 147 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 7:
670 divided by 80 is 8 with a remainder of 30.
The next digit of our result is 8. 
Result so far: 8421.8
If we subtract 640 from 670, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
When dividing 300 by 80, we get 3 with a remainder of 60.
The number 3 becomes the next digit in our result. 
Result so far: 8421.83
If we take 240 away from 300, we end up with 60.
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:
600 divided by 80 is 7 with a remainder of 40.
The next digit of our result is 7. 
Result so far: 8421.837
If we subtract 560 from 600, 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.

Let's proceed to step 10:
80 can be fit into 400 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 8421.8375
Subtract 400 from 400 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 11:
When dividing 0 by 80, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 8421.8375
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.

On to step 12:
When dividing 0 by 80, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 8421.8375
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 quotient of the division is 8421.8375, and the remainder is 0.0.
