We're dividing 403242 by 33 
We're looking to find how many times 33 goes into 403242.

Step 1:
33 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 33

Step 2:
The number 33 fits into 40 1 times, leaving a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 7 after subtracting 33 from 40.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 33

Step 3:
33 goes into 73 2 times with a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Deduct 66 from 73 and we're left with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 33

Step 4:
If we divide 72 by 33, we get 2 and a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 122.0
If we subtract 66 from 72, we get 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 33

Let's proceed to step 5:
The number 33 fits into 64 1 times, leaving a remainder of 31.
Write down 1 as next digit of the result. 
Result so far: 1221.0
The remainder is 31 after subtracting 33 from 64.
Include the next digit (2) from the dividend after 31, then repeat: 312 / 33

Going ahead to step 6:
When dividing 312 by 33, we get 9 with a remainder of 15.
Record the quotient 9 as the next digit in the result. 
Result so far: 12219.0
The remainder is 15 after subtracting 297 from 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 7:
The number 33 fits into 150 4 times, leaving a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 12219.4
The remainder is 18 after subtracting 132 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 8:
When dividing 180 by 33, we get 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 12219.45
Subtracting 165 from 180 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 9:
33 goes into 150 4 times with a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 12219.454
Deduct 132 from 150 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 10:
33 goes into 180 5 times with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 12219.4545
Subtracting 165 from 180 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 11:
If we divide 150 by 33, we get 4 and a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 12219.45454
Subtract 132 from 150 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 12:
33 goes into 180 5 times with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 12219.454545
The remainder is 15 after subtracting 165 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 13:
The number 33 fits into 150 4 times, leaving a remainder of 18.
The next digit of our result is 4. 
Result so far: 12219.4545454
Deduct 132 from 150 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 14:
The number 33 fits into 180 5 times, leaving a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 12219.45454545
If we subtract 165 from 180, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The quotient of the division is 12219.45454545, and the remainder is 1.5e-08.
