912636 divided by 45 
Let's see how many times 45 fits into 912636.

Step 1:
If we divide 9 by 45, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 45

Step 2:
The number 45 fits into 91 2 times, leaving a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 90 from 91, we get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 45

Step 3:
12 divided by 45 is 0 with a remainder of 12.
The next digit of our result is 0. 
Result so far: 20.0
If we take 0 away from 12, we end up with 12.
Include the next digit (6) from the dividend after 12, then repeat: 126 / 45

Moving on to step 4:
45 goes into 126 2 times with a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 202.0
If we subtract 90 from 126, we get 36.
Append the next digit (3) from the dividend to 36 and continue with: 363 / 45

Going ahead to step 5:
363 divided by 45 is 8 with a remainder of 3.
Put 8 as the next digit of the answer. 
Result so far: 2028.0
Deduct 360 from 363 and we're left with 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 45

Step 6:
45 can be fit into 36 0 times, resulting in a remainder of 36.
Record the quotient 0 as the next digit in the result. 
Result so far: 20280.0
Subtract 0 from 36 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 7:
360 divided by 45 is 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 20280.8
Deduct 360 from 360 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
0 divided by 45 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 20280.8
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
45 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 20280.8
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 20280.8 with a remaining 0.0.
