We're dividing 78256904 by 280 
We want to figure out the number of times 78256904 can be divided by 280.

Going ahead to step 1:
If we divide 7 by 280, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 280

On to step 2:
280 goes into 78 0 times with a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Append the next digit (2) from the dividend to 78 and continue with: 782 / 280

Moving on to step 3:
782 divided by 280 is 2 with a remainder of 222.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 560 from 782 leaves us with 222.
Grab the next digit (5) from the dividend, add it to 222, then carry on: 2225 / 280

Step 4:
280 can be fit into 2225 7 times, resulting in a remainder of 265.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
Deduct 1960 from 2225 and we're left with 265.
Append the next digit (6) from the dividend to 265 and continue with: 2656 / 280

Advancing to step 5:
The number 280 fits into 2656 9 times, leaving a remainder of 136.
The number 9 becomes the next digit in our result. 
Result so far: 279.0
If we subtract 2520 from 2656, we get 136.
Fetch the next digit (9) from the dividend, attach it to 136 and continue: 1369 / 280

Going ahead to step 6:
1369 divided by 280 is 4 with a remainder of 249.
Record the quotient 4 as the next digit in the result. 
Result so far: 2794.0
If we subtract 1120 from 1369, we get 249.
Grab the next digit (0) from the dividend, add it to 249, then carry on: 2490 / 280

Step 7:
If we divide 2490 by 280, we get 8 and a remainder of 250.
Record the quotient 8 as the next digit in the result. 
Result so far: 27948.0
The remainder is 250 after subtracting 2240 from 2490.
Bring next digit (4) of the dividend behind the 250 and repeat the process: 2504 / 280

Going ahead to step 8:
280 goes into 2504 8 times with a remainder of 264.
Put 8 as the next digit of the answer. 
Result so far: 279488.0
Subtracting 2240 from 2504 leaves us with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Let's proceed to step 9:
When dividing 2640 by 280, we get 9 with a remainder of 120.
Use 9 as the next digit of our solution. 
Result so far: 279488.9
The remainder is 120 after subtracting 2520 from 2640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 10:
280 goes into 1200 4 times with a remainder of 80.
Write down 4 as next digit of the result. 
Result so far: 279488.94
The remainder is 80 after subtracting 1120 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 11:
280 goes into 800 2 times with a remainder of 240.
Write down 2 as next digit of the result. 
Result so far: 279488.942
Subtracting 560 from 800 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 12:
280 goes into 2400 8 times with a remainder of 160.
Use 8 as the next digit of our solution. 
Result so far: 279488.9428
The remainder is 160 after subtracting 2240 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 13:
When dividing 1600 by 280, we get 5 with a remainder of 200.
Use 5 as the next digit of our solution. 
Result so far: 279488.94285
The remainder is 200 after subtracting 1400 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 14:
2000 divided by 280 is 7 with a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 279488.942857
Subtracting 1960 from 2000 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 15:
400 divided by 280 is 1 with a remainder of 120.
Write down 1 as next digit of the result. 
Result so far: 279488.9428571
If we subtract 280 from 400, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 16:
280 goes into 1200 4 times with a remainder of 80.
Write down 4 as next digit of the result. 
Result so far: 279488.94285714
Deduct 1120 from 1200 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

In conclusion, the division gives 279488.94285714 with a balance of 8e-08.
