We look at the division of 335911 by 90 
We're looking to find how many times 90 goes into 335911.

Step 1:
When dividing 3 by 90, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 90

Advancing to step 2:
90 can be fit into 33 0 times, resulting in a remainder of 33.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 33, we end up with 33.
Append the next digit (5) from the dividend to 33 and continue with: 335 / 90

On to step 3:
90 can be fit into 335 3 times, resulting in a remainder of 65.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 270 from 335, we get 65.
Include the next digit (9) from the dividend after 65, then repeat: 659 / 90

Advancing to step 4:
90 goes into 659 7 times with a remainder of 29.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
If we take 630 away from 659, we end up with 29.
Fetch the next digit (1) from the dividend, attach it to 29 and continue: 291 / 90

Going ahead to step 5:
291 divided by 90 is 3 with a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 373.0
Subtract 270 from 291 to get 21.
Bring next digit (1) of the dividend behind the 21 and repeat the process: 211 / 90

Let's proceed to step 6:
90 goes into 211 2 times with a remainder of 31.
Put 2 as the next digit of the answer. 
Result so far: 3732.0
If we take 180 away from 211, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 7:
If we divide 310 by 90, we get 3 and a remainder of 40.
Write down 3 as next digit of the result. 
Result so far: 3732.3
The remainder is 40 after subtracting 270 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 8:
90 goes into 400 4 times with a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 3732.34
The remainder is 40 after subtracting 360 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 9:
If we divide 400 by 90, we get 4 and a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 3732.344
The remainder is 40 after subtracting 360 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 3732.344 with a remaining 0.004.
