We're dividing 918609 by 45 
We want to figure out the number of times 918609 can be divided by 45.

Step 1:
9 divided by 45 is 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 45

Advancing to step 2:
The number 45 fits into 91 2 times, leaving a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 1 after subtracting 90 from 91.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 45

On to step 3:
45 can be fit into 18 0 times, resulting in a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 20.0
Subtract 0 from 18 to get 18.
Fetch the next digit (6) from the dividend, attach it to 18 and continue: 186 / 45

Advancing to step 4:
45 goes into 186 4 times with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 204.0
Deduct 180 from 186 and we're left with 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 45

Advancing to step 5:
60 divided by 45 is 1 with a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 2041.0
The remainder is 15 after subtracting 45 from 60.
Bring next digit (9) of the dividend behind the 15 and repeat the process: 159 / 45

Step 6:
45 can be fit into 159 3 times, resulting in a remainder of 24.
Record the quotient 3 as the next digit in the result. 
Result so far: 20413.0
If we take 135 away from 159, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 7:
240 divided by 45 is 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 20413.5
Subtracting 225 from 240 leaves us 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.

Going ahead to step 8:
45 can be fit into 150 3 times, resulting in a remainder of 15.
The next digit of our result is 3. 
Result so far: 20413.53
Subtracting 135 from 150 leaves us 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.

Advancing to step 9:
When dividing 150 by 45, we get 3 with a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 20413.533
Subtracting 135 from 150 leaves us 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.

After the division, we end up with 20413.533 and a remainder of 0.0015.
