Let's divide 363693 by 90
Let's see how many times 90 fits into 363693.

Advancing to step 1:
3 divided by 90 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 90

On to step 2:
90 goes into 36 0 times with a remainder of 36.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 36 after subtracting 0 from 36.
Include the next digit (3) from the dividend after 36, then repeat: 363 / 90

Advancing to step 3:
363 divided by 90 is 4 with a remainder of 3.
The next digit of our result is 4. 
Result so far: 4.0
If we take 360 away from 363, we end up with 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 90

Going ahead to step 4:
When dividing 36 by 90, we get 0 with a remainder of 36.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
Subtract 0 from 36 to get 36.
Take the next digit (9) from the dividend and append it to 36, then repeat: 369 / 90

On to step 5:
90 goes into 369 4 times with a remainder of 9.
Put 4 as the next digit of the answer. 
Result so far: 404.0
Deduct 360 from 369 and we're left with 9.
Fetch the next digit (3) from the dividend, attach it to 9 and continue: 93 / 90

Moving on to step 6:
When dividing 93 by 90, we get 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 4041.0
Subtracting 90 from 93 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
When dividing 30 by 90, we get 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 4041.0
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 8:
300 divided by 90 is 3 with a remainder of 30.
The next digit of our result is 3. 
Result so far: 4041.03
The remainder is 30 after subtracting 270 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 9:
90 goes into 300 3 times with a remainder of 30.
Put 3 as the next digit of the answer. 
Result so far: 4041.033
Subtracting 270 from 300 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

After the division, we end up with 4041.033 and a remainder of 0.003.
