740451 divided by 45 
We're looking to find how many times 45 goes into 740451.

On to step 1:
7 divided by 45 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 45

Moving on to step 2:
If we divide 74 by 45, we get 1 and a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 29 after subtracting 45 from 74.
Grab the next digit (0) from the dividend, add it to 29, then carry on: 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
Subtracting 270 from 290 leaves us with 20.
Take the next digit (4) from the dividend and append it to 20, then repeat: 204 / 45

Step 4:
45 can be fit into 204 4 times, resulting in a remainder of 24.
The next digit of our result is 4. 
Result so far: 164.0
If we subtract 180 from 204, we get 24.
Grab the next digit (5) from the dividend, add it to 24, then carry on: 245 / 45

Moving on to step 5:
The number 45 fits into 245 5 times, leaving a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 1645.0
Deduct 225 from 245 and we're left with 20.
Append the next digit (1) from the dividend to 20 and continue with: 201 / 45

On to step 6:
If we divide 201 by 45, we get 4 and a remainder of 21.
Write down 4 as next digit of the result. 
Result so far: 16454.0
The remainder is 21 after subtracting 180 from 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 7:
45 can be fit into 210 4 times, resulting in a remainder of 30.
Use 4 as the next digit of our solution. 
Result so far: 16454.4
Deduct 180 from 210 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
If we divide 300 by 45, we get 6 and a remainder of 30.
The number 6 becomes the next digit in our result. 
Result so far: 16454.46
The remainder is 30 after subtracting 270 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 9:
If we divide 300 by 45, we get 6 and a remainder of 30.
Use 6 as the next digit of our solution. 
Result so far: 16454.466
The remainder is 30 after subtracting 270 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final result is 16454.466 with a remainder of 0.003.
