We look at the division of 57300103 by 81 
We want to divide 57300103 by 81.

Going ahead to step 1:
If we divide 5 by 81, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 81

Going ahead to step 2:
57 divided by 81 is 0 with a remainder of 57.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 57 leaves us with 57.
Take the next digit (3) from the dividend and append it to 57, then repeat: 573 / 81

Going ahead to step 3:
81 can be fit into 573 7 times, resulting in a remainder of 6.
The next digit of our result is 7. 
Result so far: 7.0
Subtracting 567 from 573 leaves us with 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 81

Advancing to step 4:
If we divide 60 by 81, we get 0 and a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 70.0
The remainder is 60 after subtracting 0 from 60.
Append the next digit (0) from the dividend to 60 and continue with: 600 / 81

On to step 5:
600 divided by 81 is 7 with a remainder of 33.
The number 7 becomes the next digit in our result. 
Result so far: 707.0
The remainder is 33 after subtracting 567 from 600.
Append the next digit (1) from the dividend to 33 and continue with: 331 / 81

Advancing to step 6:
81 can be fit into 331 4 times, resulting in a remainder of 7.
Put 4 as the next digit of the answer. 
Result so far: 7074.0
Subtract 324 from 331 to get 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 81

Moving on to step 7:
81 goes into 70 0 times with a remainder of 70.
The next digit of our result is 0. 
Result so far: 70740.0
Deduct 0 from 70 and we're left with 70.
Take the next digit (3) from the dividend and append it to 70, then repeat: 703 / 81

Moving on to step 8:
If we divide 703 by 81, we get 8 and a remainder of 55.
The next digit of our result is 8. 
Result so far: 707408.0
Deduct 648 from 703 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 9:
When dividing 550 by 81, we get 6 with a remainder of 64.
The next digit of our result is 6. 
Result so far: 707408.6
The remainder is 64 after subtracting 486 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 10:
81 goes into 640 7 times with a remainder of 73.
The number 7 becomes the next digit in our result. 
Result so far: 707408.67
Subtracting 567 from 640 leaves us with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Going ahead to step 11:
When dividing 730 by 81, we get 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 707408.679
If we subtract 729 from 730, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 12:
The number 81 fits into 10 0 times, leaving a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 707408.679
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 13:
The number 81 fits into 100 1 times, leaving a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 707408.67901
Subtracting 81 from 100 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 14:
190 divided by 81 is 2 with a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 707408.679012
The remainder is 28 after subtracting 162 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 15:
If we divide 280 by 81, we get 3 and a remainder of 37.
Record the quotient 3 as the next digit in the result. 
Result so far: 707408.6790123
Subtracting 243 from 280 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 16:
81 can be fit into 370 4 times, resulting in a remainder of 46.
Use 4 as the next digit of our solution. 
Result so far: 707408.67901234
The remainder is 46 after subtracting 324 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The final outcome is 707408.67901234, with a leftover of 4.6e-08.
