We're dividing 3835 by 90 
Our goal is to divide 3835 by 90.

On to step 1:
90 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 90

Step 2:
90 goes into 38 0 times with a remainder of 38.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 38 after subtracting 0 from 38.
Append the next digit (3) from the dividend to 38 and continue with: 383 / 90

On to step 3:
90 can be fit into 383 4 times, resulting in a remainder of 23.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 360 from 383 to get 23.
Take the next digit (5) from the dividend and append it to 23, then repeat: 235 / 90

Let's proceed to step 4:
If we divide 235 by 90, we get 2 and a remainder of 55.
Put 2 as the next digit of the answer. 
Result so far: 42.0
If we subtract 180 from 235, we 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.

Let's proceed to step 5:
If we divide 550 by 90, we get 6 and a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 42.6
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 6:
90 goes into 100 1 times with a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 42.61
Deduct 90 from 100 and we're left 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.

Advancing to step 7:
90 goes into 100 1 times with a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 42.611
Subtract 90 from 100 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.

The final result is 42.611 with a remainder of 0.001.
