Let's divide 81289559 by 239
We want to divide 81289559 by 239.

Step 1:
239 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
If we take 0 away from 8, we end up with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 239

On to step 2:
If we divide 81 by 239, we get 0 and a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Grab the next digit (2) from the dividend, add it to 81, then carry on: 812 / 239

Let's proceed to step 3:
If we divide 812 by 239, we get 3 and a remainder of 95.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 717 from 812 to get 95.
Include the next digit (8) from the dividend after 95, then repeat: 958 / 239

Advancing to step 4:
958 divided by 239 is 4 with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 34.0
Subtracting 956 from 958 leaves us with 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 239

Advancing to step 5:
239 goes into 29 0 times with a remainder of 29.
The next digit of our result is 0. 
Result so far: 340.0
Subtracting 0 from 29 leaves us with 29.
Append the next digit (5) from the dividend to 29 and continue with: 295 / 239

Let's proceed to step 6:
239 can be fit into 295 1 times, resulting in a remainder of 56.
Use 1 as the next digit of our solution. 
Result so far: 3401.0
The remainder is 56 after subtracting 239 from 295.
Include the next digit (5) from the dividend after 56, then repeat: 565 / 239

Moving on to step 7:
The number 239 fits into 565 2 times, leaving a remainder of 87.
Write down 2 as next digit of the result. 
Result so far: 34012.0
If we subtract 478 from 565, we get 87.
Append the next digit (9) from the dividend to 87 and continue with: 879 / 239

Going ahead to step 8:
The number 239 fits into 879 3 times, leaving a remainder of 162.
Use 3 as the next digit of our solution. 
Result so far: 340123.0
Deduct 717 from 879 and we're left with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

On to step 9:
The number 239 fits into 1620 6 times, leaving a remainder of 186.
Put 6 as the next digit of the answer. 
Result so far: 340123.6
If we subtract 1434 from 1620, we get 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Going ahead to step 10:
239 can be fit into 1860 7 times, resulting in a remainder of 187.
The number 7 becomes the next digit in our result. 
Result so far: 340123.67
If we subtract 1673 from 1860, we get 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Step 11:
1870 divided by 239 is 7 with a remainder of 197.
The next digit of our result is 7. 
Result so far: 340123.677
Deduct 1673 from 1870 and we're left with 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

After the division, we end up with 340123.677 and a remainder of 0.0197.
