918789 divided by 45 
We want to figure out the number of times 918789 can be divided by 45.

Going ahead to step 1:
When dividing 9 by 45, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 45

Advancing to step 2:
91 divided by 45 is 2 with a remainder of 1.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 90 from 91 leaves us with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 45

Let's proceed to step 3:
If we divide 18 by 45, we get 0 and a remainder of 18.
The next digit of our result is 0. 
Result so far: 20.0
The remainder is 18 after subtracting 0 from 18.
Grab the next digit (7) from the dividend, add it to 18, then carry on: 187 / 45

Moving on to step 4:
45 can be fit into 187 4 times, resulting in a remainder of 7.
The number 4 becomes the next digit in our result. 
Result so far: 204.0
The remainder is 7 after subtracting 180 from 187.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 45

Let's proceed to step 5:
When dividing 78 by 45, we get 1 with a remainder of 33.
Put 1 as the next digit of the answer. 
Result so far: 2041.0
Subtract 45 from 78 to get 33.
Bring next digit (9) of the dividend behind the 33 and repeat the process: 339 / 45

On to step 6:
When dividing 339 by 45, we get 7 with a remainder of 24.
Record the quotient 7 as the next digit in the result. 
Result so far: 20417.0
Subtract 315 from 339 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 7:
The number 45 fits into 240 5 times, leaving a remainder of 15.
The next digit of our result is 5. 
Result so far: 20417.5
Subtract 225 from 240 to 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.

Step 8:
150 divided by 45 is 3 with a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 20417.53
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.
Write down 3 as next digit of the result. 
Result so far: 20417.533
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 20417.533 and a remainder of 0.0015.
