900445 ÷ 18 
We want to figure out the number of times 900445 can be divided by 18.

Going ahead to step 1:
The number 18 fits into 9 0 times, leaving a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 18

Let's proceed to step 2:
When dividing 90 by 18, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we subtract 90 from 90, we get 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 18

Advancing to step 3:
18 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 50.0
If we take 0 away from 0, we end up with 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 18

Moving on to step 4:
18 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 500.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 18

Advancing to step 5:
The number 18 fits into 44 2 times, leaving a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 5002.0
If we subtract 36 from 44, we get 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 18

Moving on to step 6:
85 divided by 18 is 4 with a remainder of 13.
Use 4 as the next digit of our solution. 
Result so far: 50024.0
The remainder is 13 after subtracting 72 from 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 7:
130 divided by 18 is 7 with a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 50024.7
Deduct 126 from 130 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 8:
40 divided by 18 is 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 50024.72
The remainder is 4 after subtracting 36 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
40 divided by 18 is 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 50024.722
Subtract 36 from 40 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 50024.722 with a remainder of 0.0004.
