We look at the division of 740449 by 45 
We're looking to find how many times 45 goes into 740449.

Going ahead to step 1:
If we divide 7 by 45, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 45

Moving on to step 2:
74 divided by 45 is 1 with a remainder of 29.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 45 from 74, we get 29.
Take the next digit (0) from the dividend and append it to 29, then repeat: 290 / 45

Moving on to step 3:
45 goes into 290 6 times with a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 16.0
The remainder is 20 after subtracting 270 from 290.
Bring next digit (4) of the dividend behind the 20 and repeat the process: 204 / 45

Step 4:
204 divided by 45 is 4 with a remainder of 24.
The next digit of our result is 4. 
Result so far: 164.0
Subtract 180 from 204 to get 24.
Include the next digit (4) from the dividend after 24, then repeat: 244 / 45

On to step 5:
45 can be fit into 244 5 times, resulting in a remainder of 19.
Record the quotient 5 as the next digit in the result. 
Result so far: 1645.0
Deduct 225 from 244 and we're left with 19.
Take the next digit (9) from the dividend and append it to 19, then repeat: 199 / 45

Let's proceed to step 6:
45 goes into 199 4 times with a remainder of 19.
Record the quotient 4 as the next digit in the result. 
Result so far: 16454.0
Deduct 180 from 199 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 7:
190 divided by 45 is 4 with a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 16454.4
The remainder is 10 after subtracting 180 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
The number 45 fits into 100 2 times, leaving a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 16454.42
Subtract 90 from 100 to 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.

On to step 9:
100 divided by 45 is 2 with a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 16454.422
Subtracting 90 from 100 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.

Our division results in 16454.422 with a remaining 0.001.
