303931 divided by 57 
We're looking to find how many times 57 goes into 303931.

Advancing to step 1:
When dividing 3 by 57, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 57

Going ahead to step 2:
When dividing 30 by 57, we get 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Append the next digit (3) from the dividend to 30 and continue with: 303 / 57

On to step 3:
57 goes into 303 5 times with a remainder of 18.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 285 from 303 and we're left with 18.
Include the next digit (9) from the dividend after 18, then repeat: 189 / 57

Moving on to step 4:
If we divide 189 by 57, we get 3 and a remainder of 18.
Put 3 as the next digit of the answer. 
Result so far: 53.0
The remainder is 18 after subtracting 171 from 189.
Append the next digit (3) from the dividend to 18 and continue with: 183 / 57

On to step 5:
57 can be fit into 183 3 times, resulting in a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 533.0
Deduct 171 from 183 and we're left with 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 57

Going ahead to step 6:
If we divide 121 by 57, we get 2 and a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 5332.0
The remainder is 7 after subtracting 114 from 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 7:
If we divide 70 by 57, we get 1 and a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 5332.1
If we take 57 away from 70, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 8:
When dividing 130 by 57, we get 2 with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 5332.12
If we subtract 114 from 130, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 9:
57 can be fit into 160 2 times, resulting in a remainder of 46.
The next digit of our result is 2. 
Result so far: 5332.122
Subtract 114 from 160 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

After the division, we end up with 5332.122 and a remainder of 0.0046.
