404245 ÷ 90 
Let's see how many times 90 fits into 404245.

Moving on to step 1:
The number 90 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 90

Let's proceed to step 2:
The number 90 fits into 40 0 times, leaving a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 40 leaves us with 40.
Bring next digit (4) of the dividend behind the 40 and repeat the process: 404 / 90

Advancing to step 3:
404 divided by 90 is 4 with a remainder of 44.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 360 from 404 to get 44.
Include the next digit (2) from the dividend after 44, then repeat: 442 / 90

Moving on to step 4:
442 divided by 90 is 4 with a remainder of 82.
The next digit of our result is 4. 
Result so far: 44.0
The remainder is 82 after subtracting 360 from 442.
Grab the next digit (4) from the dividend, add it to 82, then carry on: 824 / 90

Advancing to step 5:
The number 90 fits into 824 9 times, leaving a remainder of 14.
Use 9 as the next digit of our solution. 
Result so far: 449.0
Subtracting 810 from 824 leaves us with 14.
Include the next digit (5) from the dividend after 14, then repeat: 145 / 90

On to step 6:
The number 90 fits into 145 1 times, leaving a remainder of 55.
Record the quotient 1 as the next digit in the result. 
Result so far: 4491.0
Subtract 90 from 145 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 7:
90 goes into 550 6 times with a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 4491.6
Subtract 540 from 550 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.

Advancing to step 8:
The number 90 fits into 100 1 times, leaving a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 4491.61
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.

Moving on to step 9:
When dividing 100 by 90, we get 1 with a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 4491.611
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 4491.611 with a remaining 0.001.
