We're dividing 81296369 by 573 
We want to divide 81296369 by 573.

On to step 1:
If we divide 8 by 573, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
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 / 573

Advancing to step 2:
When dividing 81 by 573, we get 0 with a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Include the next digit (2) from the dividend after 81, then repeat: 812 / 573

Advancing to step 3:
If we divide 812 by 573, we get 1 and a remainder of 239.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 573 from 812, we get 239.
Append the next digit (9) from the dividend to 239 and continue with: 2399 / 573

Advancing to step 4:
The number 573 fits into 2399 4 times, leaving a remainder of 107.
The next digit of our result is 4. 
Result so far: 14.0
Deduct 2292 from 2399 and we're left with 107.
Fetch the next digit (6) from the dividend, attach it to 107 and continue: 1076 / 573

On to step 5:
573 goes into 1076 1 times with a remainder of 503.
Record the quotient 1 as the next digit in the result. 
Result so far: 141.0
If we take 573 away from 1076, we end up with 503.
Grab the next digit (3) from the dividend, add it to 503, then carry on: 5033 / 573

Moving on to step 6:
573 goes into 5033 8 times with a remainder of 449.
Use 8 as the next digit of our solution. 
Result so far: 1418.0
The remainder is 449 after subtracting 4584 from 5033.
Fetch the next digit (6) from the dividend, attach it to 449 and continue: 4496 / 573

Moving on to step 7:
573 goes into 4496 7 times with a remainder of 485.
Record the quotient 7 as the next digit in the result. 
Result so far: 14187.0
The remainder is 485 after subtracting 4011 from 4496.
Append the next digit (9) from the dividend to 485 and continue with: 4859 / 573

Going ahead to step 8:
4859 divided by 573 is 8 with a remainder of 275.
Use 8 as the next digit of our solution. 
Result so far: 141878.0
If we subtract 4584 from 4859, we get 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Moving on to step 9:
2750 divided by 573 is 4 with a remainder of 458.
Use 4 as the next digit of our solution. 
Result so far: 141878.4
If we take 2292 away from 2750, we end up with 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

Advancing to step 10:
573 can be fit into 4580 7 times, resulting in a remainder of 569.
Put 7 as the next digit of the answer. 
Result so far: 141878.47
Subtracting 4011 from 4580 leaves us with 569.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5690, and continue the process.

Step 11:
If we divide 5690 by 573, we get 9 and a remainder of 533.
Write down 9 as next digit of the result. 
Result so far: 141878.479
The remainder is 533 after subtracting 5157 from 5690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5330, and continue the process.

On to step 12:
The number 573 fits into 5330 9 times, leaving a remainder of 173.
Put 9 as the next digit of the answer. 
Result so far: 141878.4799
The remainder is 173 after subtracting 5157 from 5330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

The final result is 141878.4799 with a remainder of 0.00173.
