919291 ÷ 45 
We're looking to find how many times 45 goes into 919291.

Moving on to step 1:
When dividing 9 by 45, we get 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 45

On to step 2:
If we divide 91 by 45, we get 2 and a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 90 from 91, we get 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 45

Let's proceed to step 3:
When dividing 19 by 45, we get 0 with a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Subtract 0 from 19 to get 19.
Append the next digit (2) from the dividend to 19 and continue with: 192 / 45

Going ahead to step 4:
45 goes into 192 4 times with a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 204.0
Subtracting 180 from 192 leaves us with 12.
Bring next digit (9) of the dividend behind the 12 and repeat the process: 129 / 45

Step 5:
If we divide 129 by 45, we get 2 and a remainder of 39.
The number 2 becomes the next digit in our result. 
Result so far: 2042.0
The remainder is 39 after subtracting 90 from 129.
Append the next digit (1) from the dividend to 39 and continue with: 391 / 45

Moving on to step 6:
391 divided by 45 is 8 with a remainder of 31.
The number 8 becomes the next digit in our result. 
Result so far: 20428.0
The remainder is 31 after subtracting 360 from 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 7:
45 can be fit into 310 6 times, resulting in a remainder of 40.
Write down 6 as next digit of the result. 
Result so far: 20428.6
Deduct 270 from 310 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 8:
When dividing 400 by 45, we get 8 with a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 20428.68
Deduct 360 from 400 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 9:
When dividing 400 by 45, we get 8 with a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 20428.688
Subtract 360 from 400 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

In conclusion, the division gives 20428.688 with a balance of 0.004.
