3624 divided by 90 
We want to divide 3624 by 90.

Step 1:
3 divided by 90 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 90

On to step 2:
90 can be fit into 36 0 times, resulting in a remainder of 36.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 36 leaves us with 36.
Take the next digit (2) from the dividend and append it to 36, then repeat: 362 / 90

Step 3:
90 can be fit into 362 4 times, resulting in a remainder of 2.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 360 from 362 and we're left with 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 90

On to step 4:
If we divide 24 by 90, we get 0 and a remainder of 24.
The next digit of our result is 0. 
Result so far: 40.0
Subtract 0 from 24 to 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.

Advancing to step 5:
90 can be fit into 240 2 times, resulting in a remainder of 60.
The number 2 becomes the next digit in our result. 
Result so far: 40.2
If we subtract 180 from 240, we 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.

On to step 6:
The number 90 fits into 600 6 times, leaving a remainder of 60.
The next digit of our result is 6. 
Result so far: 40.26
Deduct 540 from 600 and we're left 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.

Moving on to step 7:
The number 90 fits into 600 6 times, leaving a remainder of 60.
The next digit of our result is 6. 
Result so far: 40.266
Subtracting 540 from 600 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.

Our division results in 40.266 with a remaining 0.006.
