We divide 421444 by 18
We're looking to find how many times 18 goes into 421444.

Let's proceed to step 1:
If we divide 4 by 18, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 18

Going ahead to step 2:
18 can be fit into 42 2 times, resulting in a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 36 from 42 to get 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 18

Advancing to step 3:
The number 18 fits into 61 3 times, leaving a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
If we subtract 54 from 61, we get 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 18

On to step 4:
When dividing 74 by 18, we get 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 234.0
The remainder is 2 after subtracting 72 from 74.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 18

Going ahead to step 5:
The number 18 fits into 24 1 times, leaving a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 2341.0
The remainder is 6 after subtracting 18 from 24.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 18

Step 6:
64 divided by 18 is 3 with a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 23413.0
Subtracting 54 from 64 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 7:
The number 18 fits into 100 5 times, leaving a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 23413.5
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
When dividing 100 by 18, we get 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 23413.55
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The quotient of the division is 23413.55, and the remainder is 0.01.
