30857 divided by 6 
We want to figure out the number of times 30857 can be divided by 6.

Going ahead to step 1:
The number 6 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 6

Moving on to step 2:
6 goes into 30 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we take 30 away from 30, we end up with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 6

On to step 3:
6 can be fit into 8 1 times, resulting in a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 51.0
Deduct 6 from 8 and we're left with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 6

Step 4:
The number 6 fits into 25 4 times, leaving a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 514.0
Subtracting 24 from 25 leaves us with 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 6

Advancing to step 5:
When dividing 17 by 6, we get 2 with a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 5142.0
Deduct 12 from 17 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 6:
If we divide 50 by 6, we get 8 and a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 5142.8
If we subtract 48 from 50, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
20 divided by 6 is 3 with a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 5142.83
Subtracting 18 from 20 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
6 goes into 20 3 times with a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 5142.833
If we take 18 away from 20, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Our division results in 5142.833 with a remaining 0.0002.
