Let's divide 451464 by 90
We're looking to find how many times 90 goes into 451464.

On to step 1:
The number 90 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 90

On to step 2:
90 goes into 45 0 times with a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 45 after subtracting 0 from 45.
Include the next digit (1) from the dividend after 45, then repeat: 451 / 90

Let's proceed to step 3:
When dividing 451 by 90, we get 5 with a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we subtract 450 from 451, we get 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 90

Step 4:
If we divide 14 by 90, we get 0 and a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 50.0
If we take 0 away from 14, we end up with 14.
Bring next digit (6) of the dividend behind the 14 and repeat the process: 146 / 90

Going ahead to step 5:
When dividing 146 by 90, we get 1 with a remainder of 56.
The next digit of our result is 1. 
Result so far: 501.0
Subtract 90 from 146 to get 56.
Bring next digit (4) of the dividend behind the 56 and repeat the process: 564 / 90

Advancing to step 6:
564 divided by 90 is 6 with a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 5016.0
If we subtract 540 from 564, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 7:
90 goes into 240 2 times with a remainder of 60.
The number 2 becomes the next digit in our result. 
Result so far: 5016.2
Subtracting 180 from 240 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 8:
600 divided by 90 is 6 with a remainder of 60.
The next digit of our result is 6. 
Result so far: 5016.26
The remainder is 60 after subtracting 540 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 9:
If we divide 600 by 90, we get 6 and a remainder of 60.
The number 6 becomes the next digit in our result. 
Result so far: 5016.266
Subtract 540 from 600 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The quotient of the division is 5016.266, and the remainder is 0.006.
