We're dividing 135403 by 33 
Let's see how many times 33 fits into 135403.

On to step 1:
1 divided by 33 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 33

On to step 2:
When dividing 13 by 33, we get 0 with a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Fetch the next digit (5) from the dividend, attach it to 13 and continue: 135 / 33

Let's proceed to step 3:
If we divide 135 by 33, we get 4 and a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 132 from 135 leaves us with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 33

Going ahead to step 4:
33 goes into 34 1 times with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 41.0
The remainder is 1 after subtracting 33 from 34.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 33

Step 5:
33 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 410.0
If we subtract 0 from 10, we get 10.
Grab the next digit (3) from the dividend, add it to 10, then carry on: 103 / 33

Going ahead to step 6:
If we divide 103 by 33, we get 3 and a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 4103.0
Subtracting 99 from 103 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
33 goes into 40 1 times with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 4103.1
Deduct 33 from 40 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 8:
When dividing 70 by 33, we get 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 4103.12
Subtracting 66 from 70 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
When dividing 40 by 33, we get 1 with a remainder of 7.
The next digit of our result is 1. 
Result so far: 4103.121
Deduct 33 from 40 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 10:
33 goes into 70 2 times with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 4103.1212
Subtracting 66 from 70 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 11:
When dividing 40 by 33, we get 1 with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 4103.12121
Subtracting 33 from 40 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 12:
If we divide 70 by 33, we get 2 and a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 4103.121212
Deduct 66 from 70 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 13:
33 goes into 40 1 times with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 4103.1212121
Subtract 33 from 40 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 14:
The number 33 fits into 70 2 times, leaving a remainder of 4.
The next digit of our result is 2. 
Result so far: 4103.12121212
If we subtract 66 from 70, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 4103.12121212 with a remaining 4e-09.
