We divide 88231359 by 280
We want to divide 88231359 by 280.

Advancing to step 1:
280 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 280

Advancing to step 2:
When dividing 88 by 280, we get 0 with a remainder of 88.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 88 to get 88.
Fetch the next digit (2) from the dividend, attach it to 88 and continue: 882 / 280

Moving on to step 3:
If we divide 882 by 280, we get 3 and a remainder of 42.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 840 from 882 leaves us with 42.
Bring next digit (3) of the dividend behind the 42 and repeat the process: 423 / 280

Moving on to step 4:
280 can be fit into 423 1 times, resulting in a remainder of 143.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
The remainder is 143 after subtracting 280 from 423.
Take the next digit (1) from the dividend and append it to 143, then repeat: 1431 / 280

On to step 5:
When dividing 1431 by 280, we get 5 with a remainder of 31.
The next digit of our result is 5. 
Result so far: 315.0
The remainder is 31 after subtracting 1400 from 1431.
Append the next digit (3) from the dividend to 31 and continue with: 313 / 280

Advancing to step 6:
313 divided by 280 is 1 with a remainder of 33.
Put 1 as the next digit of the answer. 
Result so far: 3151.0
The remainder is 33 after subtracting 280 from 313.
Grab the next digit (5) from the dividend, add it to 33, then carry on: 335 / 280

Going ahead to step 7:
If we divide 335 by 280, we get 1 and a remainder of 55.
Use 1 as the next digit of our solution. 
Result so far: 31511.0
Subtracting 280 from 335 leaves us with 55.
Append the next digit (9) from the dividend to 55 and continue with: 559 / 280

Step 8:
559 divided by 280 is 1 with a remainder of 279.
Write down 1 as next digit of the result. 
Result so far: 315111.0
Deduct 280 from 559 and we're left with 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Advancing to step 9:
280 goes into 2790 9 times with a remainder of 270.
Record the quotient 9 as the next digit in the result. 
Result so far: 315111.9
Subtract 2520 from 2790 to get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Step 10:
The number 280 fits into 2700 9 times, leaving a remainder of 180.
Put 9 as the next digit of the answer. 
Result so far: 315111.99
The remainder is 180 after subtracting 2520 from 2700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

The quotient of the division is 315111.99, and the remainder is 0.18.
