Let's divide 670561 by 80
Let's see how many times 80 fits into 670561.

Moving on to step 1:
80 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
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

Let's proceed 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
If we subtract 0 from 67, we get 67.
Bring next digit (0) of the dividend behind the 67 and repeat the process: 670 / 80

Let's proceed to step 3:
When dividing 670 by 80, we get 8 with a remainder of 30.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 640 from 670 and we're left with 30.
Bring next digit (5) of the dividend behind the 30 and repeat the process: 305 / 80

Step 4:
When dividing 305 by 80, we get 3 with a remainder of 65.
Record the quotient 3 as the next digit in the result. 
Result so far: 83.0
If we take 240 away from 305, we end up with 65.
Fetch the next digit (6) from the dividend, attach it to 65 and continue: 656 / 80

Step 5:
The number 80 fits into 656 8 times, leaving a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 838.0
If we take 640 away from 656, we end up with 16.
Bring next digit (1) of the dividend behind the 16 and repeat the process: 161 / 80

Step 6:
161 divided by 80 is 2 with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 8382.0
Deduct 160 from 161 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
80 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 8382.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
When dividing 100 by 80, we get 1 with a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 8382.01
If we take 80 away from 100, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
200 divided by 80 is 2 with a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 8382.012
If we subtract 160 from 200, 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.

Going ahead to step 10:
When dividing 400 by 80, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 8382.0125
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.

Let's proceed to step 11:
0 divided by 80 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 8382.0125
The remainder is 0 after subtracting 0 from 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:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 8382.0125
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.

Our division results in 8382.0125 with a remaining 0.0.
