We're dividing 821707 by 18 
We want to figure out the number of times 821707 can be divided by 18.

Going ahead to step 1:
8 divided by 18 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (2) from the dividend and append it to 8, then repeat: 82 / 18

Let's proceed to step 2:
When dividing 82 by 18, we get 4 with a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 72 from 82 and we're left with 10.
Bring next digit (1) of the dividend behind the 10 and repeat the process: 101 / 18

Step 3:
When dividing 101 by 18, we get 5 with a remainder of 11.
The number 5 becomes the next digit in our result. 
Result so far: 45.0
If we take 90 away from 101, we end up with 11.
Append the next digit (7) from the dividend to 11 and continue with: 117 / 18

Moving on to step 4:
The number 18 fits into 117 6 times, leaving a remainder of 9.
Put 6 as the next digit of the answer. 
Result so far: 456.0
Subtracting 108 from 117 leaves us with 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 18

On to step 5:
90 divided by 18 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 4565.0
Deduct 90 from 90 and we're left with 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 18

Let's proceed to step 6:
7 divided by 18 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 45650.0
Deduct 0 from 7 and we're left 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.

Moving on to step 7:
18 goes into 70 3 times with a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 45650.3
The remainder is 16 after subtracting 54 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 8:
When dividing 160 by 18, we get 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 45650.38
If we subtract 144 from 160, 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.

On to step 9:
18 can be fit into 160 8 times, resulting in a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 45650.388
Deduct 144 from 160 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 45650.388 with a remainder of 0.0016.
