We look at the division of 453445 by 18 
Our goal is to divide 453445 by 18.

Let's proceed to step 1:
If we divide 4 by 18, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 18

Let's proceed to step 2:
The number 18 fits into 45 2 times, leaving a remainder of 9.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 36 away from 45, we end up with 9.
Fetch the next digit (3) from the dividend, attach it to 9 and continue: 93 / 18

Advancing to step 3:
When dividing 93 by 18, we get 5 with a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 25.0
If we take 90 away from 93, we end up with 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 18

On to step 4:
18 goes into 34 1 times with a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 251.0
Deduct 18 from 34 and we're left with 16.
Take the next digit (4) from the dividend and append it to 16, then repeat: 164 / 18

On to step 5:
18 can be fit into 164 9 times, resulting in a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 2519.0
The remainder is 2 after subtracting 162 from 164.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 18

Let's proceed to step 6:
18 can be fit into 25 1 times, resulting in a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 25191.0
If we subtract 18 from 25, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 7:
18 can be fit into 70 3 times, resulting in a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 25191.3
If we subtract 54 from 70, 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.

Let's proceed to step 8:
If we divide 160 by 18, we get 8 and a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 25191.38
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.

Advancing to step 9:
The number 18 fits into 160 8 times, leaving a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 25191.388
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.

The quotient of the division is 25191.388, and the remainder is 0.0016.
