Let's divide 647458 by 18
Our goal is to divide 647458 by 18.

Step 1:
18 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 18

Moving on to step 2:
If we divide 64 by 18, we get 3 and a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 54 from 64 and we're left with 10.
Bring next digit (7) of the dividend behind the 10 and repeat the process: 107 / 18

Let's proceed to step 3:
The number 18 fits into 107 5 times, leaving a remainder of 17.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
Deduct 90 from 107 and we're left with 17.
Bring next digit (4) of the dividend behind the 17 and repeat the process: 174 / 18

Advancing to step 4:
18 goes into 174 9 times with a remainder of 12.
The number 9 becomes the next digit in our result. 
Result so far: 359.0
Deduct 162 from 174 and we're left with 12.
Take the next digit (5) from the dividend and append it to 12, then repeat: 125 / 18

On to step 5:
If we divide 125 by 18, we get 6 and a remainder of 17.
Record the quotient 6 as the next digit in the result. 
Result so far: 3596.0
The remainder is 17 after subtracting 108 from 125.
Fetch the next digit (8) from the dividend, attach it to 17 and continue: 178 / 18

Moving on to step 6:
18 can be fit into 178 9 times, resulting in a remainder of 16.
The number 9 becomes the next digit in our result. 
Result so far: 35969.0
Subtracting 162 from 178 leaves us 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.

Step 7:
160 divided by 18 is 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 35969.8
Subtract 144 from 160 to 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 8:
If we divide 160 by 18, we get 8 and a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 35969.88
The remainder is 16 after subtracting 144 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 35969.88 and a remainder of 0.016.
