We divide 451725 by 18
Let's see how many times 18 fits into 451725.

On to step 1:
18 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 18

Going ahead to step 2:
If we divide 45 by 18, we get 2 and a remainder of 9.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 36 away from 45, we end up with 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 18

Going ahead to step 3:
If we divide 91 by 18, we get 5 and a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 25.0
Subtract 90 from 91 to get 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 18

Advancing to step 4:
If we divide 17 by 18, we get 0 and a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 250.0
Deduct 0 from 17 and we're left with 17.
Bring next digit (2) of the dividend behind the 17 and repeat the process: 172 / 18

Moving on to step 5:
18 can be fit into 172 9 times, resulting in a remainder of 10.
Use 9 as the next digit of our solution. 
Result so far: 2509.0
Subtracting 162 from 172 leaves us with 10.
Grab the next digit (5) from the dividend, add it to 10, then carry on: 105 / 18

Step 6:
105 divided by 18 is 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 25095.0
If we subtract 90 from 105, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 7:
150 divided by 18 is 8 with a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 25095.8
The remainder is 6 after subtracting 144 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 8:
18 goes into 60 3 times with a remainder of 6.
The next digit of our result is 3. 
Result so far: 25095.83
If we subtract 54 from 60, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 9:
The number 18 fits into 60 3 times, leaving a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 25095.833
If we take 54 away from 60, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The quotient of the division is 25095.833, and the remainder is 0.0006.
