909042 ÷ 45 
We want to figure out the number of times 909042 can be divided by 45.

On to step 1:
When dividing 9 by 45, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 45

Going ahead to step 2:
The number 45 fits into 90 2 times, leaving a remainder of 0.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 90 from 90 and we're left with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 45

Going ahead to step 3:
45 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 20.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 45

Let's proceed to step 4:
The number 45 fits into 90 2 times, leaving a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 202.0
Deduct 90 from 90 and we're left with 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 45

Let's proceed to step 5:
If we divide 4 by 45, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 2020.0
If we subtract 0 from 4, we get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 45

On to step 6:
45 goes into 42 0 times with a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 20200.0
Subtracting 0 from 42 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 7:
The number 45 fits into 420 9 times, leaving a remainder of 15.
Put 9 as the next digit of the answer. 
Result so far: 20200.9
If we subtract 405 from 420, 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.

Moving on to step 8:
45 can be fit into 150 3 times, resulting in a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 20200.93
If we take 135 away from 150, we end up with 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 9:
When dividing 150 by 45, we get 3 with a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 20200.933
If we subtract 135 from 150, 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.

The quotient of the division is 20200.933, and the remainder is 0.0015.
