57064663 divided by 815 
We want to divide 57064663 by 815.

Going ahead to step 1:
The number 815 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 815

Let's proceed to step 2:
When dividing 57 by 815, we get 0 with a remainder of 57.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 57, we get 57.
Take the next digit (0) from the dividend and append it to 57, then repeat: 570 / 815

Advancing to step 3:
The number 815 fits into 570 0 times, leaving a remainder of 570.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 570 leaves us with 570.
Include the next digit (6) from the dividend after 570, then repeat: 5706 / 815

Going ahead to step 4:
When dividing 5706 by 815, we get 7 with a remainder of 1.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 5705 from 5706, we get 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 815

Moving on to step 5:
815 goes into 14 0 times with a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 70.0
Subtracting 0 from 14 leaves us with 14.
Grab the next digit (6) from the dividend, add it to 14, then carry on: 146 / 815

Moving on to step 6:
If we divide 146 by 815, we get 0 and a remainder of 146.
Put 0 as the next digit of the answer. 
Result so far: 700.0
Deduct 0 from 146 and we're left with 146.
Grab the next digit (6) from the dividend, add it to 146, then carry on: 1466 / 815

Moving on to step 7:
815 goes into 1466 1 times with a remainder of 651.
Record the quotient 1 as the next digit in the result. 
Result so far: 7001.0
Deduct 815 from 1466 and we're left with 651.
Include the next digit (3) from the dividend after 651, then repeat: 6513 / 815

On to step 8:
6513 divided by 815 is 7 with a remainder of 808.
Put 7 as the next digit of the answer. 
Result so far: 70017.0
Subtract 5705 from 6513 to get 808.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8080, and continue the process.

On to step 9:
8080 divided by 815 is 9 with a remainder of 745.
Record the quotient 9 as the next digit in the result. 
Result so far: 70017.9
If we take 7335 away from 8080, we end up with 745.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7450, and continue the process.

Let's proceed to step 10:
815 can be fit into 7450 9 times, resulting in a remainder of 115.
Write down 9 as next digit of the result. 
Result so far: 70017.99
Deduct 7335 from 7450 and we're left with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

After the division, we end up with 70017.99 and a remainder of 0.115.
