We look at the division of 81389040 by 564 
We want to divide 81389040 by 564.

Going ahead to step 1:
564 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 564

Let's proceed to step 2:
If we divide 81 by 564, we get 0 and a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Include the next digit (3) from the dividend after 81, then repeat: 813 / 564

On to step 3:
564 goes into 813 1 times with a remainder of 249.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 564 from 813, we get 249.
Include the next digit (8) from the dividend after 249, then repeat: 2498 / 564

Advancing to step 4:
2498 divided by 564 is 4 with a remainder of 242.
The next digit of our result is 4. 
Result so far: 14.0
Subtracting 2256 from 2498 leaves us with 242.
Include the next digit (9) from the dividend after 242, then repeat: 2429 / 564

Step 5:
564 can be fit into 2429 4 times, resulting in a remainder of 173.
Put 4 as the next digit of the answer. 
Result so far: 144.0
Deduct 2256 from 2429 and we're left with 173.
Bring next digit (0) of the dividend behind the 173 and repeat the process: 1730 / 564

On to step 6:
564 can be fit into 1730 3 times, resulting in a remainder of 38.
Record the quotient 3 as the next digit in the result. 
Result so far: 1443.0
If we take 1692 away from 1730, we end up with 38.
Append the next digit (4) from the dividend to 38 and continue with: 384 / 564

Going ahead to step 7:
564 goes into 384 0 times with a remainder of 384.
The next digit of our result is 0. 
Result so far: 14430.0
If we take 0 away from 384, we end up with 384.
Bring next digit (0) of the dividend behind the 384 and repeat the process: 3840 / 564

Going ahead to step 8:
When dividing 3840 by 564, we get 6 with a remainder of 456.
Record the quotient 6 as the next digit in the result. 
Result so far: 144306.0
The remainder is 456 after subtracting 3384 from 3840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

On to step 9:
The number 564 fits into 4560 8 times, leaving a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 144306.8
Subtracting 4512 from 4560 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 10:
480 divided by 564 is 0 with a remainder of 480.
The next digit of our result is 0. 
Result so far: 144306.8
The remainder is 480 after subtracting 0 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Moving on to step 11:
4800 divided by 564 is 8 with a remainder of 288.
The next digit of our result is 8. 
Result so far: 144306.808
Subtracting 4512 from 4800 leaves us with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Let's proceed to step 12:
2880 divided by 564 is 5 with a remainder of 60.
Record the quotient 5 as the next digit in the result. 
Result so far: 144306.8085
Deduct 2820 from 2880 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 13:
600 divided by 564 is 1 with a remainder of 36.
Record the quotient 1 as the next digit in the result. 
Result so far: 144306.80851
The remainder is 36 after subtracting 564 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 14:
564 can be fit into 360 0 times, resulting in a remainder of 360.
Put 0 as the next digit of the answer. 
Result so far: 144306.80851
Subtract 0 from 360 to get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

On to step 15:
The number 564 fits into 3600 6 times, leaving a remainder of 216.
Use 6 as the next digit of our solution. 
Result so far: 144306.8085106
Deduct 3384 from 3600 and we're left with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

On to step 16:
564 can be fit into 2160 3 times, resulting in a remainder of 468.
Use 3 as the next digit of our solution. 
Result so far: 144306.80851063
The remainder is 468 after subtracting 1692 from 2160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

The final outcome is 144306.80851063, with a leftover of 4.68e-07.
