920521 divided by 45 
We're looking to find how many times 45 goes into 920521.

Going ahead to step 1:
The number 45 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (2) of the dividend behind the 9 and repeat the process: 92 / 45

Going ahead to step 2:
If we divide 92 by 45, we get 2 and a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 2 after subtracting 90 from 92.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 45

Moving on to step 3:
20 divided by 45 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
The remainder is 20 after subtracting 0 from 20.
Bring next digit (5) of the dividend behind the 20 and repeat the process: 205 / 45

Step 4:
45 goes into 205 4 times with a remainder of 25.
Write down 4 as next digit of the result. 
Result so far: 204.0
If we take 180 away from 205, we end up with 25.
Bring next digit (2) of the dividend behind the 25 and repeat the process: 252 / 45

On to step 5:
45 goes into 252 5 times with a remainder of 27.
Write down 5 as next digit of the result. 
Result so far: 2045.0
Deduct 225 from 252 and we're left with 27.
Bring next digit (1) of the dividend behind the 27 and repeat the process: 271 / 45

Let's proceed to step 6:
45 can be fit into 271 6 times, resulting in a remainder of 1.
The next digit of our result is 6. 
Result so far: 20456.0
The remainder is 1 after subtracting 270 from 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
If we divide 10 by 45, we get 0 and a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 20456.0
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
45 can be fit into 100 2 times, resulting in a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 20456.02
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 9:
100 divided by 45 is 2 with a remainder of 10.
The next digit of our result is 2. 
Result so far: 20456.022
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 20456.022 with a remaining 0.001.
