We're dividing 306340 by 57 
Our goal is to divide 306340 by 57.

Going ahead to step 1:
57 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 57

Step 2:
57 can be fit into 30 0 times, resulting in 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.
Bring next digit (6) of the dividend behind the 30 and repeat the process: 306 / 57

Going ahead to step 3:
57 can be fit into 306 5 times, resulting in a remainder of 21.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 285 from 306 to get 21.
Take the next digit (3) from the dividend and append it to 21, then repeat: 213 / 57

Going ahead to step 4:
57 goes into 213 3 times with a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 53.0
If we subtract 171 from 213, we get 42.
Fetch the next digit (4) from the dividend, attach it to 42 and continue: 424 / 57

Moving on to step 5:
If we divide 424 by 57, we get 7 and a remainder of 25.
Use 7 as the next digit of our solution. 
Result so far: 537.0
If we take 399 away from 424, we end up with 25.
Grab the next digit (0) from the dividend, add it to 25, then carry on: 250 / 57

Going ahead to step 6:
57 goes into 250 4 times with a remainder of 22.
Record the quotient 4 as the next digit in the result. 
Result so far: 5374.0
Subtract 228 from 250 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 7:
If we divide 220 by 57, we get 3 and a remainder of 49.
The next digit of our result is 3. 
Result so far: 5374.3
Subtracting 171 from 220 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 8:
When dividing 490 by 57, we get 8 with a remainder of 34.
Write down 8 as next digit of the result. 
Result so far: 5374.38
If we subtract 456 from 490, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 9:
340 divided by 57 is 5 with a remainder of 55.
The next digit of our result is 5. 
Result so far: 5374.385
Subtracting 285 from 340 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 10:
The number 57 fits into 550 9 times, leaving a remainder of 37.
Put 9 as the next digit of the answer. 
Result so far: 5374.3859
Deduct 513 from 550 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 11:
If we divide 370 by 57, we get 6 and a remainder of 28.
Record the quotient 6 as the next digit in the result. 
Result so far: 5374.38596
The remainder is 28 after subtracting 342 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 12:
280 divided by 57 is 4 with a remainder of 52.
Put 4 as the next digit of the answer. 
Result so far: 5374.385964
If we take 228 away from 280, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 13:
520 divided by 57 is 9 with a remainder of 7.
The next digit of our result is 9. 
Result so far: 5374.3859649
Subtracting 513 from 520 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 14:
57 goes into 70 1 times with a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 5374.38596491
Subtracting 57 from 70 leaves us 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.

The final outcome is 5374.38596491, with a leftover of 1.3e-08.
