Let's divide 630920 by 80
We want to figure out the number of times 630920 can be divided by 80.

On to step 1:
When dividing 6 by 80, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 80

Step 2:
80 can be fit into 63 0 times, resulting in a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 63 leaves us with 63.
Grab the next digit (0) from the dividend, add it to 63, then carry on: 630 / 80

Going ahead to step 3:
80 can be fit into 630 7 times, resulting in a remainder of 70.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we subtract 560 from 630, we get 70.
Take the next digit (9) from the dividend and append it to 70, then repeat: 709 / 80

Going ahead to step 4:
80 can be fit into 709 8 times, resulting in a remainder of 69.
The next digit of our result is 8. 
Result so far: 78.0
If we take 640 away from 709, we end up with 69.
Include the next digit (2) from the dividend after 69, then repeat: 692 / 80

Step 5:
692 divided by 80 is 8 with a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 788.0
Subtract 640 from 692 to get 52.
Take the next digit (0) from the dividend and append it to 52, then repeat: 520 / 80

On to step 6:
80 goes into 520 6 times with a remainder of 40.
Write down 6 as next digit of the result. 
Result so far: 7886.0
The remainder is 40 after subtracting 480 from 520.
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 7:
When dividing 400 by 80, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 7886.5
Deduct 400 from 400 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.

On to step 8:
80 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 7886.5
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.

Let's proceed to step 9:
80 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 7886.5
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 final result is 7886.5 with a remainder of 0.0.
