453611 ÷ 18 
We want to figure out the number of times 453611 can be divided by 18.

Let's proceed to step 1:
18 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 18

Let's proceed to step 2:
If we divide 45 by 18, we get 2 and a remainder of 9.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 36 from 45 to get 9.
Fetch the next digit (3) from the dividend, attach it to 9 and continue: 93 / 18

On to step 3:
If we divide 93 by 18, we get 5 and a remainder of 3.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
Deduct 90 from 93 and we're left with 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 18

Let's proceed to step 4:
When dividing 36 by 18, we get 2 with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 252.0
Subtracting 36 from 36 leaves us with 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 18

Step 5:
18 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 2520.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 18

Going ahead to step 6:
18 can be fit into 11 0 times, resulting in a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 25200.0
If we take 0 away from 11, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 7:
If we divide 110 by 18, we get 6 and a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 25200.6
The remainder is 2 after subtracting 108 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 8:
20 divided by 18 is 1 with a remainder of 2.
The next digit of our result is 1. 
Result so far: 25200.61
Subtract 18 from 20 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 9:
The number 18 fits into 20 1 times, leaving a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 25200.611
If we subtract 18 from 20, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Our division results in 25200.611 with a remaining 0.0002.
