We're dividing 57038940 by 804 
We want to divide 57038940 by 804.

Going ahead to step 1:
The number 804 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 804

Advancing to step 2:
804 goes into 57 0 times with a remainder of 57.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 57 leaves us with 57.
Fetch the next digit (0) from the dividend, attach it to 57 and continue: 570 / 804

Going ahead to step 3:
The number 804 fits into 570 0 times, leaving a remainder of 570.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 570, we end up with 570.
Fetch the next digit (3) from the dividend, attach it to 570 and continue: 5703 / 804

Going ahead to step 4:
The number 804 fits into 5703 7 times, leaving a remainder of 75.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
The remainder is 75 after subtracting 5628 from 5703.
Grab the next digit (8) from the dividend, add it to 75, then carry on: 758 / 804

Advancing to step 5:
When dividing 758 by 804, we get 0 with a remainder of 758.
The number 0 becomes the next digit in our result. 
Result so far: 70.0
Deduct 0 from 758 and we're left with 758.
Include the next digit (9) from the dividend after 758, then repeat: 7589 / 804

Advancing to step 6:
804 goes into 7589 9 times with a remainder of 353.
The number 9 becomes the next digit in our result. 
Result so far: 709.0
If we subtract 7236 from 7589, we get 353.
Take the next digit (4) from the dividend and append it to 353, then repeat: 3534 / 804

Advancing to step 7:
804 goes into 3534 4 times with a remainder of 318.
Use 4 as the next digit of our solution. 
Result so far: 7094.0
If we take 3216 away from 3534, we end up with 318.
Append the next digit (0) from the dividend to 318 and continue with: 3180 / 804

Advancing to step 8:
If we divide 3180 by 804, we get 3 and a remainder of 768.
The number 3 becomes the next digit in our result. 
Result so far: 70943.0
Subtract 2412 from 3180 to get 768.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7680, and continue the process.

Going ahead to step 9:
804 goes into 7680 9 times with a remainder of 444.
Put 9 as the next digit of the answer. 
Result so far: 70943.9
Deduct 7236 from 7680 and we're left with 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

On to step 10:
804 goes into 4440 5 times with a remainder of 420.
Put 5 as the next digit of the answer. 
Result so far: 70943.95
Subtract 4020 from 4440 to get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Advancing to step 11:
4200 divided by 804 is 5 with a remainder of 180.
Write down 5 as next digit of the result. 
Result so far: 70943.955
If we take 4020 away from 4200, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

The final result is 70943.955 with a remainder of 0.018.
