670799 divided by 80 
Let's see how many times 80 fits into 670799.

On to step 1:
6 divided by 80 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 80

Advancing to step 2:
80 goes into 67 0 times with a remainder of 67.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 67 and we're left with 67.
Include the next digit (0) from the dividend after 67, then repeat: 670 / 80

Let's proceed to step 3:
When dividing 670 by 80, we get 8 with a remainder of 30.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 640 from 670 leaves us with 30.
Bring next digit (7) of the dividend behind the 30 and repeat the process: 307 / 80

Step 4:
If we divide 307 by 80, we get 3 and a remainder of 67.
Put 3 as the next digit of the answer. 
Result so far: 83.0
The remainder is 67 after subtracting 240 from 307.
Grab the next digit (9) from the dividend, add it to 67, then carry on: 679 / 80

Moving on to step 5:
If we divide 679 by 80, we get 8 and a remainder of 39.
Record the quotient 8 as the next digit in the result. 
Result so far: 838.0
The remainder is 39 after subtracting 640 from 679.
Fetch the next digit (9) from the dividend, attach it to 39 and continue: 399 / 80

Let's proceed to step 6:
399 divided by 80 is 4 with a remainder of 79.
The next digit of our result is 4. 
Result so far: 8384.0
If we subtract 320 from 399, we get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Let's proceed to step 7:
When dividing 790 by 80, we get 9 with a remainder of 70.
Use 9 as the next digit of our solution. 
Result so far: 8384.9
Deduct 720 from 790 and we're left 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.

Moving on to step 8:
The number 80 fits into 700 8 times, leaving a remainder of 60.
Put 8 as the next digit of the answer. 
Result so far: 8384.98
Deduct 640 from 700 and we're left 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.

Step 9:
If we divide 600 by 80, we get 7 and a remainder of 40.
The number 7 becomes the next digit in our result. 
Result so far: 8384.987
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.
The next digit of our result is 5. 
Result so far: 8384.9875
Subtracting 400 from 400 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.

Advancing to step 11:
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: 8384.9875
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.

Step 12:
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: 8384.9875
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.

In conclusion, the division gives 8384.9875 with a balance of 0.0.
