We're dividing 917925 by 45 
We're looking to find how many times 45 goes into 917925.

Let's proceed to step 1:
The number 45 fits into 9 0 times, leaving a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 45

Advancing to step 2:
91 divided by 45 is 2 with a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 1 after subtracting 90 from 91.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 45

Let's proceed to step 3:
45 can be fit into 17 0 times, resulting in a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Subtract 0 from 17 to get 17.
Append the next digit (9) from the dividend to 17 and continue with: 179 / 45

Let's proceed to step 4:
45 can be fit into 179 3 times, resulting in a remainder of 44.
Record the quotient 3 as the next digit in the result. 
Result so far: 203.0
Subtract 135 from 179 to get 44.
Append the next digit (2) from the dividend to 44 and continue with: 442 / 45

On to step 5:
45 goes into 442 9 times with a remainder of 37.
The next digit of our result is 9. 
Result so far: 2039.0
If we subtract 405 from 442, we get 37.
Bring next digit (5) of the dividend behind the 37 and repeat the process: 375 / 45

Moving on to step 6:
If we divide 375 by 45, we get 8 and a remainder of 15.
Record the quotient 8 as the next digit in the result. 
Result so far: 20398.0
Subtracting 360 from 375 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.

Moving on to step 7:
45 goes into 150 3 times with a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 20398.3
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 8:
45 goes into 150 3 times with a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 20398.33
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.

After the division, we end up with 20398.33 and a remainder of 0.015.
