366454 ÷ 45 
We want to figure out the number of times 366454 can be divided by 45.

Let's proceed to step 1:
The number 45 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 45

Step 2:
When dividing 36 by 45, we get 0 with a remainder of 36.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 36 to get 36.
Take the next digit (6) from the dividend and append it to 36, then repeat: 366 / 45

On to step 3:
The number 45 fits into 366 8 times, leaving a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtracting 360 from 366 leaves us with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 45

Going ahead to step 4:
45 goes into 64 1 times with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 81.0
Subtracting 45 from 64 leaves us with 19.
Bring next digit (5) of the dividend behind the 19 and repeat the process: 195 / 45

Let's proceed to step 5:
45 goes into 195 4 times with a remainder of 15.
Use 4 as the next digit of our solution. 
Result so far: 814.0
The remainder is 15 after subtracting 180 from 195.
Grab the next digit (4) from the dividend, add it to 15, then carry on: 154 / 45

Going ahead to step 6:
The number 45 fits into 154 3 times, leaving a remainder of 19.
Record the quotient 3 as the next digit in the result. 
Result so far: 8143.0
The remainder is 19 after subtracting 135 from 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 7:
When dividing 190 by 45, we get 4 with a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 8143.4
Subtract 180 from 190 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.

Going ahead to step 8:
100 divided by 45 is 2 with a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 8143.42
If we take 90 away from 100, we end up 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.

Advancing to step 9:
When dividing 100 by 45, we get 2 with a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 8143.422
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 8143.422 with a remainder of 0.001.
