857313 ÷ 18 
We want to divide 857313 by 18.

Step 1:
If we divide 8 by 18, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 18

Step 2:
18 goes into 85 4 times with a remainder of 13.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 13 after subtracting 72 from 85.
Take the next digit (7) from the dividend and append it to 13, then repeat: 137 / 18

Step 3:
18 can be fit into 137 7 times, resulting in a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 47.0
Deduct 126 from 137 and we're left with 11.
Include the next digit (3) from the dividend after 11, then repeat: 113 / 18

On to step 4:
If we divide 113 by 18, we get 6 and a remainder of 5.
Write down 6 as next digit of the result. 
Result so far: 476.0
Subtracting 108 from 113 leaves us with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 18

Moving on to step 5:
18 can be fit into 51 2 times, resulting in a remainder of 15.
Put 2 as the next digit of the answer. 
Result so far: 4762.0
The remainder is 15 after subtracting 36 from 51.
Include the next digit (3) from the dividend after 15, then repeat: 153 / 18

On to step 6:
18 can be fit into 153 8 times, resulting in a remainder of 9.
The next digit of our result is 8. 
Result so far: 47628.0
Subtracting 144 from 153 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 7:
When dividing 90 by 18, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 47628.5
If we subtract 90 from 90, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
If we divide 0 by 18, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 47628.5
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
If we divide 0 by 18, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 47628.5
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 47628.5, and the remainder is 0.0.
