57815357 divided by 808 
We're looking to find how many times 808 goes into 57815357.

Going ahead to step 1:
808 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 808

Advancing to step 2:
57 divided by 808 is 0 with a remainder of 57.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 57, we get 57.
Take the next digit (8) from the dividend and append it to 57, then repeat: 578 / 808

On to step 3:
If we divide 578 by 808, we get 0 and a remainder of 578.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 578 to get 578.
Include the next digit (1) from the dividend after 578, then repeat: 5781 / 808

On to step 4:
The number 808 fits into 5781 7 times, leaving a remainder of 125.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 5656 from 5781 leaves us with 125.
Include the next digit (5) from the dividend after 125, then repeat: 1255 / 808

Going ahead to step 5:
808 can be fit into 1255 1 times, resulting in a remainder of 447.
Write down 1 as next digit of the result. 
Result so far: 71.0
If we subtract 808 from 1255, we get 447.
Bring next digit (3) of the dividend behind the 447 and repeat the process: 4473 / 808

Moving on to step 6:
When dividing 4473 by 808, we get 5 with a remainder of 433.
The number 5 becomes the next digit in our result. 
Result so far: 715.0
If we take 4040 away from 4473, we end up with 433.
Fetch the next digit (5) from the dividend, attach it to 433 and continue: 4335 / 808

Let's proceed to step 7:
808 can be fit into 4335 5 times, resulting in a remainder of 295.
The next digit of our result is 5. 
Result so far: 7155.0
Subtracting 4040 from 4335 leaves us with 295.
Append the next digit (7) from the dividend to 295 and continue with: 2957 / 808

On to step 8:
If we divide 2957 by 808, we get 3 and a remainder of 533.
The number 3 becomes the next digit in our result. 
Result so far: 71553.0
If we subtract 2424 from 2957, we get 533.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5330, and continue the process.

Let's proceed to step 9:
808 goes into 5330 6 times with a remainder of 482.
Put 6 as the next digit of the answer. 
Result so far: 71553.6
Deduct 4848 from 5330 and we're left with 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Advancing to step 10:
4820 divided by 808 is 5 with a remainder of 780.
The next digit of our result is 5. 
Result so far: 71553.65
Subtract 4040 from 4820 to get 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

Going ahead to step 11:
808 can be fit into 7800 9 times, resulting in a remainder of 528.
Write down 9 as next digit of the result. 
Result so far: 71553.659
If we subtract 7272 from 7800, we get 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Going ahead to step 12:
The number 808 fits into 5280 6 times, leaving a remainder of 432.
Use 6 as the next digit of our solution. 
Result so far: 71553.6596
Subtracting 4848 from 5280 leaves us with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Advancing to step 13:
808 can be fit into 4320 5 times, resulting in a remainder of 280.
Record the quotient 5 as the next digit in the result. 
Result so far: 71553.65965
Subtract 4040 from 4320 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 14:
808 can be fit into 2800 3 times, resulting in a remainder of 376.
The number 3 becomes the next digit in our result. 
Result so far: 71553.659653
Subtract 2424 from 2800 to get 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Step 15:
808 can be fit into 3760 4 times, resulting in a remainder of 528.
Record the quotient 4 as the next digit in the result. 
Result so far: 71553.6596534
If we take 3232 away from 3760, we end up with 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Advancing to step 16:
The number 808 fits into 5280 6 times, leaving a remainder of 432.
The next digit of our result is 6. 
Result so far: 71553.65965346
Deduct 4848 from 5280 and we're left with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

The final result is 71553.65965346 with a remainder of 4.32e-07.
