We divide 453771 by 45
We're looking to find how many times 45 goes into 453771.

Let's proceed to step 1:
4 divided by 45 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 45

Moving on to step 2:
45 can be fit into 45 1 times, resulting in a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 45 from 45 and we're left with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 45

Going ahead to step 3:
3 divided by 45 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 10.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 45

On to step 4:
45 goes into 37 0 times with a remainder of 37.
Write down 0 as next digit of the result. 
Result so far: 100.0
Subtract 0 from 37 to get 37.
Include the next digit (7) from the dividend after 37, then repeat: 377 / 45

Step 5:
377 divided by 45 is 8 with a remainder of 17.
Use 8 as the next digit of our solution. 
Result so far: 1008.0
Subtracting 360 from 377 leaves us with 17.
Append the next digit (1) from the dividend to 17 and continue with: 171 / 45

On to step 6:
45 goes into 171 3 times with a remainder of 36.
Write down 3 as next digit of the result. 
Result so far: 10083.0
The remainder is 36 after subtracting 135 from 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 7:
360 divided by 45 is 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 10083.8
Subtract 360 from 360 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
The number 45 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10083.8
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
45 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10083.8
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 10083.8 and a remainder of 0.0.
