403399 divided by 33 
Let's see how many times 33 fits into 403399.

Going ahead to step 1:
33 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 33

Going ahead to step 2:
33 goes into 40 1 times with 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.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 33

Moving on to step 3:
The number 33 fits into 73 2 times, leaving a remainder of 7.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we subtract 66 from 73, we get 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 33

Step 4:
If we divide 73 by 33, we get 2 and a remainder of 7.
The next digit of our result is 2. 
Result so far: 122.0
If we take 66 away from 73, we end up with 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 33

On to step 5:
When dividing 79 by 33, we get 2 with a remainder of 13.
The next digit of our result is 2. 
Result so far: 1222.0
Deduct 66 from 79 and we're left with 13.
Fetch the next digit (9) from the dividend, attach it to 13 and continue: 139 / 33

139 divided by 33 is 4 with a remainder of 7.
Record the quotient 4 as the next digit in the result. 
Result so far: 12224.0
If we take 132 away from 139, we end up 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 7:
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: 12224.2
The remainder is 4 after subtracting 66 from 70.
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 8:
33 goes into 40 1 times with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 12224.21
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.

Step 9:
When dividing 70 by 33, we get 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 12224.212
Subtract 66 from 70 to 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.

Advancing to step 10:
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: 12224.2121
If we take 33 away from 40, we end up 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.

On to step 11:
33 can be fit into 70 2 times, resulting in a remainder of 4.
The next digit of our result is 2. 
Result so far: 12224.21212
Subtract 66 from 70 to 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.

Advancing to step 12:
If we divide 40 by 33, we get 1 and a remainder of 7.
The next digit of our result is 1. 
Result so far: 12224.212121
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 13:
33 goes into 70 2 times with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 12224.2121212
If we take 66 away from 70, we end up 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 14:
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: 12224.21212121
The remainder is 7 after subtracting 33 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

In conclusion, the division gives 12224.21212121 with a balance of 7e-09.
