We're dividing 645047 by 18 
We want to divide 645047 by 18.

Step 1:
18 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 18

Let's proceed to step 2:
The number 18 fits into 64 3 times, leaving a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 54 from 64, we get 10.
Include the next digit (5) from the dividend after 10, then repeat: 105 / 18

Moving on to step 3:
If we divide 105 by 18, we get 5 and a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
If we take 90 away from 105, we end up with 15.
Fetch the next digit (0) from the dividend, attach it to 15 and continue: 150 / 18

Step 4:
18 can be fit into 150 8 times, resulting in a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 358.0
Subtract 144 from 150 to get 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 18

Advancing to step 5:
The number 18 fits into 64 3 times, leaving a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 3583.0
The remainder is 10 after subtracting 54 from 64.
Grab the next digit (7) from the dividend, add it to 10, then carry on: 107 / 18

Step 6:
If we divide 107 by 18, we get 5 and a remainder of 17.
Use 5 as the next digit of our solution. 
Result so far: 35835.0
Subtracting 90 from 107 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 7:
If we divide 170 by 18, we get 9 and a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 35835.9
Deduct 162 from 170 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 8:
The number 18 fits into 80 4 times, leaving a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 35835.94
If we take 72 away from 80, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
80 divided by 18 is 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 35835.944
Deduct 72 from 80 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 35835.944, and the remainder is 0.0008.
