Let's divide 81039608 by 289
Let's see how many times 289 fits into 81039608.

Moving on to step 1:
289 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 289

Let's proceed to step 2:
The number 289 fits into 81 0 times, leaving a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Include the next digit (0) from the dividend after 81, then repeat: 810 / 289

Advancing to step 3:
289 can be fit into 810 2 times, resulting in a remainder of 232.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 578 from 810 leaves us with 232.
Bring next digit (3) of the dividend behind the 232 and repeat the process: 2323 / 289

Going ahead to step 4:
When dividing 2323 by 289, we get 8 with a remainder of 11.
Use 8 as the next digit of our solution. 
Result so far: 28.0
If we subtract 2312 from 2323, we get 11.
Append the next digit (9) from the dividend to 11 and continue with: 119 / 289

Let's proceed to step 5:
119 divided by 289 is 0 with a remainder of 119.
The next digit of our result is 0. 
Result so far: 280.0
Deduct 0 from 119 and we're left with 119.
Append the next digit (6) from the dividend to 119 and continue with: 1196 / 289

Moving on to step 6:
1196 divided by 289 is 4 with a remainder of 40.
Record the quotient 4 as the next digit in the result. 
Result so far: 2804.0
If we take 1156 away from 1196, we end up with 40.
Bring next digit (0) of the dividend behind the 40 and repeat the process: 400 / 289

Step 7:
400 divided by 289 is 1 with a remainder of 111.
Record the quotient 1 as the next digit in the result. 
Result so far: 28041.0
If we take 289 away from 400, we end up with 111.
Append the next digit (8) from the dividend to 111 and continue with: 1118 / 289

Step 8:
The number 289 fits into 1118 3 times, leaving a remainder of 251.
Record the quotient 3 as the next digit in the result. 
Result so far: 280413.0
Subtracting 867 from 1118 leaves us with 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Let's proceed to step 9:
289 goes into 2510 8 times with a remainder of 198.
Record the quotient 8 as the next digit in the result. 
Result so far: 280413.8
If we take 2312 away from 2510, we end up with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Going ahead to step 10:
1980 divided by 289 is 6 with a remainder of 246.
The next digit of our result is 6. 
Result so far: 280413.86
Subtracting 1734 from 1980 leaves us with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

On to step 11:
If we divide 2460 by 289, we get 8 and a remainder of 148.
Record the quotient 8 as the next digit in the result. 
Result so far: 280413.868
If we subtract 2312 from 2460, we get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Going ahead to step 12:
If we divide 1480 by 289, we get 5 and a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 280413.8685
If we subtract 1445 from 1480, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 13:
350 divided by 289 is 1 with a remainder of 61.
Use 1 as the next digit of our solution. 
Result so far: 280413.86851
Deduct 289 from 350 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 14:
289 goes into 610 2 times with a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 280413.868512
If we take 578 away from 610, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 15:
If we divide 320 by 289, we get 1 and a remainder of 31.
Use 1 as the next digit of our solution. 
Result so far: 280413.8685121
Deduct 289 from 320 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 16:
310 divided by 289 is 1 with a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 280413.86851211
The remainder is 21 after subtracting 289 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

The final result is 280413.86851211 with a remainder of 2.1e-08.
