Let's divide 404120 by 45
We're looking to find how many times 45 goes into 404120.

Step 1:
When dividing 4 by 45, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 45

Moving on to step 2:
The number 45 fits into 40 0 times, leaving a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Take the next digit (4) from the dividend and append it to 40, then repeat: 404 / 45

Step 3:
The number 45 fits into 404 8 times, leaving a remainder of 44.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 360 from 404 to get 44.
Append the next digit (1) from the dividend to 44 and continue with: 441 / 45

Advancing to step 4:
45 goes into 441 9 times with a remainder of 36.
The number 9 becomes the next digit in our result. 
Result so far: 89.0
If we subtract 405 from 441, we get 36.
Include the next digit (2) from the dividend after 36, then repeat: 362 / 45

On to step 5:
The number 45 fits into 362 8 times, leaving a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 898.0
The remainder is 2 after subtracting 360 from 362.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 45

Step 6:
When dividing 20 by 45, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 8980.0
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 7:
If we divide 200 by 45, we get 4 and a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 8980.4
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
200 divided by 45 is 4 with a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 8980.44
Subtract 180 from 200 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 8980.44, with a leftover of 0.02.
