We divide 81259423 by 564
We want to divide 81259423 by 564.

On to step 1:
8 divided by 564 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 564

Moving on to step 2:
When dividing 81 by 564, we get 0 with a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Fetch the next digit (2) from the dividend, attach it to 81 and continue: 812 / 564

On to step 3:
564 goes into 812 1 times with a remainder of 248.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 248 after subtracting 564 from 812.
Append the next digit (5) from the dividend to 248 and continue with: 2485 / 564

Moving on to step 4:
2485 divided by 564 is 4 with a remainder of 229.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Subtract 2256 from 2485 to get 229.
Include the next digit (9) from the dividend after 229, then repeat: 2299 / 564

Going ahead to step 5:
The number 564 fits into 2299 4 times, leaving a remainder of 43.
Write down 4 as next digit of the result. 
Result so far: 144.0
Deduct 2256 from 2299 and we're left with 43.
Fetch the next digit (4) from the dividend, attach it to 43 and continue: 434 / 564

Let's proceed to step 6:
When dividing 434 by 564, we get 0 with a remainder of 434.
Write down 0 as next digit of the result. 
Result so far: 1440.0
If we take 0 away from 434, we end up with 434.
Take the next digit (2) from the dividend and append it to 434, then repeat: 4342 / 564

Going ahead to step 7:
564 goes into 4342 7 times with a remainder of 394.
The number 7 becomes the next digit in our result. 
Result so far: 14407.0
The remainder is 394 after subtracting 3948 from 4342.
Bring next digit (3) of the dividend behind the 394 and repeat the process: 3943 / 564

Step 8:
If we divide 3943 by 564, we get 6 and a remainder of 559.
Record the quotient 6 as the next digit in the result. 
Result so far: 144076.0
Subtract 3384 from 3943 to get 559.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5590, and continue the process.

Moving on to step 9:
564 goes into 5590 9 times with a remainder of 514.
Use 9 as the next digit of our solution. 
Result so far: 144076.9
Subtracting 5076 from 5590 leaves us with 514.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5140, and continue the process.

Step 10:
The number 564 fits into 5140 9 times, leaving a remainder of 64.
Write down 9 as next digit of the result. 
Result so far: 144076.99
Deduct 5076 from 5140 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final result is 144076.99 with a remainder of 0.064.
