920553 ÷ 45 
We're looking to find how many times 45 goes into 920553.

Advancing to step 1:
When dividing 9 by 45, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (2) from the dividend to 9 and continue with: 92 / 45

Moving on to step 2:
45 can be fit into 92 2 times, resulting in a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 90 from 92 and we're left with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 45

Let's proceed to step 3:
45 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Deduct 0 from 20 and we're left with 20.
Include the next digit (5) from the dividend after 20, then repeat: 205 / 45

Moving on to step 4:
When dividing 205 by 45, we get 4 with a remainder of 25.
Write down 4 as next digit of the result. 
Result so far: 204.0
Subtract 180 from 205 to get 25.
Append the next digit (5) from the dividend to 25 and continue with: 255 / 45

Moving on to step 5:
If we divide 255 by 45, we get 5 and a remainder of 30.
The next digit of our result is 5. 
Result so far: 2045.0
Subtracting 225 from 255 leaves us with 30.
Append the next digit (3) from the dividend to 30 and continue with: 303 / 45

Let's proceed to step 6:
The number 45 fits into 303 6 times, leaving a remainder of 33.
Put 6 as the next digit of the answer. 
Result so far: 20456.0
Subtract 270 from 303 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 7:
45 can be fit into 330 7 times, resulting in a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 20456.7
Deduct 315 from 330 and we're left 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.

On to step 8:
The number 45 fits into 150 3 times, leaving a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 20456.73
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:
The number 45 fits into 150 3 times, leaving a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 20456.733
Deduct 135 from 150 and we're left 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 20456.733 and a remainder of 0.0015.
