Let's divide 670996 by 80
We want to divide 670996 by 80.

Moving on to step 1:
6 divided by 80 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 80

Moving on to step 2:
80 goes into 67 0 times with a remainder of 67.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 67, we get 67.
Append the next digit (0) from the dividend to 67 and continue with: 670 / 80

On to step 3:
The number 80 fits into 670 8 times, leaving a remainder of 30.
The next digit of our result is 8. 
Result so far: 8.0
If we take 640 away from 670, we end up with 30.
Fetch the next digit (9) from the dividend, attach it to 30 and continue: 309 / 80

On to step 4:
The number 80 fits into 309 3 times, leaving a remainder of 69.
Use 3 as the next digit of our solution. 
Result so far: 83.0
Deduct 240 from 309 and we're left with 69.
Grab the next digit (9) from the dividend, add it to 69, then carry on: 699 / 80

Step 5:
The number 80 fits into 699 8 times, leaving a remainder of 59.
The next digit of our result is 8. 
Result so far: 838.0
If we take 640 away from 699, we end up with 59.
Bring next digit (6) of the dividend behind the 59 and repeat the process: 596 / 80

Going ahead to step 6:
80 can be fit into 596 7 times, resulting in a remainder of 36.
Write down 7 as next digit of the result. 
Result so far: 8387.0
If we subtract 560 from 596, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 7:
The number 80 fits into 360 4 times, leaving a remainder of 40.
Record the quotient 4 as the next digit in the result. 
Result so far: 8387.4
Deduct 320 from 360 and we're left 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.

On to step 8:
If we divide 400 by 80, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 8387.45
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.

On to step 9:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 8387.45
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.

On to step 10:
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: 8387.45
Subtract 0 from 0 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.

After the division, we end up with 8387.45 and a remainder of 0.0.
