630159 divided by 80 
We want to divide 630159 by 80.

Moving on to step 1:
The number 80 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 80

Step 2:
80 goes into 63 0 times with a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 63, we get 63.
Include the next digit (0) from the dividend after 63, then repeat: 630 / 80

Going ahead to step 3:
630 divided by 80 is 7 with a remainder of 70.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 560 from 630 to get 70.
Append the next digit (1) from the dividend to 70 and continue with: 701 / 80

Moving on to step 4:
701 divided by 80 is 8 with a remainder of 61.
Write down 8 as next digit of the result. 
Result so far: 78.0
If we subtract 640 from 701, we get 61.
Append the next digit (5) from the dividend to 61 and continue with: 615 / 80

Moving on to step 5:
615 divided by 80 is 7 with a remainder of 55.
Record the quotient 7 as the next digit in the result. 
Result so far: 787.0
If we subtract 560 from 615, we get 55.
Append the next digit (9) from the dividend to 55 and continue with: 559 / 80

Moving on to step 6:
80 can be fit into 559 6 times, resulting in a remainder of 79.
The next digit of our result is 6. 
Result so far: 7876.0
The remainder is 79 after subtracting 480 from 559.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Advancing to step 7:
When dividing 790 by 80, we get 9 with a remainder of 70.
Record the quotient 9 as the next digit in the result. 
Result so far: 7876.9
If we take 720 away from 790, we end up 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:
700 divided by 80 is 8 with a remainder of 60.
The next digit of our result is 8. 
Result so far: 7876.98
The remainder is 60 after subtracting 640 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 9:
600 divided by 80 is 7 with a remainder of 40.
Write down 7 as next digit of the result. 
Result so far: 7876.987
Subtract 560 from 600 to 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.

Step 10:
80 can be fit into 400 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 7876.9875
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.

Moving on to step 11:
If we divide 0 by 80, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 7876.9875
If we subtract 0 from 0, we 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.

Going ahead to step 12:
When dividing 0 by 80, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 7876.9875
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.

In conclusion, the division gives 7876.9875 with a balance of 0.0.
