57321075 ÷ 809 
Let's see how many times 809 fits into 57321075.

On to step 1:
5 divided by 809 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 809

Moving on to step 2:
809 can be fit into 57 0 times, resulting in a remainder of 57.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 57 to get 57.
Fetch the next digit (3) from the dividend, attach it to 57 and continue: 573 / 809

Advancing to step 3:
The number 809 fits into 573 0 times, leaving a remainder of 573.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 573 to get 573.
Take the next digit (2) from the dividend and append it to 573, then repeat: 5732 / 809

Let's proceed to step 4:
The number 809 fits into 5732 7 times, leaving a remainder of 69.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we take 5663 away from 5732, we end up with 69.
Include the next digit (1) from the dividend after 69, then repeat: 691 / 809

On to step 5:
If we divide 691 by 809, we get 0 and a remainder of 691.
Record the quotient 0 as the next digit in the result. 
Result so far: 70.0
If we take 0 away from 691, we end up with 691.
Bring next digit (0) of the dividend behind the 691 and repeat the process: 6910 / 809

Let's proceed to step 6:
6910 divided by 809 is 8 with a remainder of 438.
Record the quotient 8 as the next digit in the result. 
Result so far: 708.0
If we subtract 6472 from 6910, we get 438.
Grab the next digit (7) from the dividend, add it to 438, then carry on: 4387 / 809

Advancing to step 7:
809 goes into 4387 5 times with a remainder of 342.
The next digit of our result is 5. 
Result so far: 7085.0
Subtract 4045 from 4387 to get 342.
Fetch the next digit (5) from the dividend, attach it to 342 and continue: 3425 / 809

Moving on to step 8:
The number 809 fits into 3425 4 times, leaving a remainder of 189.
Use 4 as the next digit of our solution. 
Result so far: 70854.0
The remainder is 189 after subtracting 3236 from 3425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Let's proceed to step 9:
The number 809 fits into 1890 2 times, leaving a remainder of 272.
The number 2 becomes the next digit in our result. 
Result so far: 70854.2
Deduct 1618 from 1890 and we're left with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Let's proceed to step 10:
2720 divided by 809 is 3 with a remainder of 293.
Record the quotient 3 as the next digit in the result. 
Result so far: 70854.23
If we take 2427 away from 2720, we end up with 293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

Let's proceed to step 11:
The number 809 fits into 2930 3 times, leaving a remainder of 503.
Record the quotient 3 as the next digit in the result. 
Result so far: 70854.233
Deduct 2427 from 2930 and we're left with 503.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5030, and continue the process.

The final outcome is 70854.233, with a leftover of 0.0503.
