We look at the division of 393553 by 33 
Let's see how many times 33 fits into 393553.

Going ahead to step 1:
33 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 33

Advancing to step 2:
When dividing 39 by 33, we get 1 with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 33 from 39 and we're left with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 33

Step 3:
When dividing 63 by 33, we get 1 with a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
The remainder is 30 after subtracting 33 from 63.
Fetch the next digit (5) from the dividend, attach it to 30 and continue: 305 / 33

Step 4:
33 goes into 305 9 times with a remainder of 8.
The next digit of our result is 9. 
Result so far: 119.0
If we take 297 away from 305, we end up with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 33

Going ahead to step 5:
The number 33 fits into 85 2 times, leaving a remainder of 19.
Write down 2 as next digit of the result. 
Result so far: 1192.0
The remainder is 19 after subtracting 66 from 85.
Grab the next digit (3) from the dividend, add it to 19, then carry on: 193 / 33

Advancing to step 6:
33 can be fit into 193 5 times, resulting in a remainder of 28.
Write down 5 as next digit of the result. 
Result so far: 11925.0
Deduct 165 from 193 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 7:
The number 33 fits into 280 8 times, leaving a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 11925.8
Subtract 264 from 280 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 8:
When dividing 160 by 33, we get 4 with a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 11925.84
If we take 132 away from 160, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 9:
33 goes into 280 8 times with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 11925.848
The remainder is 16 after subtracting 264 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 10:
When dividing 160 by 33, we get 4 with a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 11925.8484
Subtract 132 from 160 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 11:
33 goes into 280 8 times with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 11925.84848
If we take 264 away from 280, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 12:
If we divide 160 by 33, we get 4 and a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 11925.848484
Subtract 132 from 160 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 13:
When dividing 280 by 33, we get 8 with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 11925.8484848
Subtract 264 from 280 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 14:
When dividing 160 by 33, we get 4 with a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 11925.84848484
The remainder is 28 after subtracting 132 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final outcome is 11925.84848484, with a leftover of 2.8e-08.
