902492 ÷ 45 
We want to figure out the number of times 902492 can be divided by 45.

Going ahead to step 1:
If we divide 9 by 45, we get 0 and a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 45

Going ahead to step 2:
If we divide 90 by 45, we get 2 and a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 90 from 90 to get 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 45

Step 3:
If we divide 2 by 45, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 45

Advancing to step 4:
45 can be fit into 24 0 times, resulting in a remainder of 24.
The number 0 becomes the next digit in our result. 
Result so far: 200.0
The remainder is 24 after subtracting 0 from 24.
Grab the next digit (9) from the dividend, add it to 24, then carry on: 249 / 45

Going ahead to step 5:
The number 45 fits into 249 5 times, leaving a remainder of 24.
Record the quotient 5 as the next digit in the result. 
Result so far: 2005.0
Subtract 225 from 249 to get 24.
Take the next digit (2) from the dividend and append it to 24, then repeat: 242 / 45

Advancing to step 6:
45 can be fit into 242 5 times, resulting in a remainder of 17.
Use 5 as the next digit of our solution. 
Result so far: 20055.0
Subtracting 225 from 242 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 7:
170 divided by 45 is 3 with a remainder of 35.
The number 3 becomes the next digit in our result. 
Result so far: 20055.3
If we subtract 135 from 170, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 8:
350 divided by 45 is 7 with a remainder of 35.
The next digit of our result is 7. 
Result so far: 20055.37
Subtract 315 from 350 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 9:
If we divide 350 by 45, we get 7 and a remainder of 35.
Put 7 as the next digit of the answer. 
Result so far: 20055.377
If we take 315 away from 350, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Our division results in 20055.377 with a remaining 0.0035.
