393174 ÷ 33 
We want to figure out the number of times 393174 can be divided by 33.

Step 1:
33 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 33

Step 2:
The number 33 fits into 39 1 times, leaving a remainder of 6.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 33 from 39, we get 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.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Deduct 33 from 63 and we're left with 30.
Append the next digit (1) from the dividend to 30 and continue with: 301 / 33

Moving on to step 4:
33 goes into 301 9 times with a remainder of 4.
The next digit of our result is 9. 
Result so far: 119.0
Subtract 297 from 301 to get 4.
Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 33

Moving on to step 5:
47 divided by 33 is 1 with a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 1191.0
Subtracting 33 from 47 leaves us with 14.
Bring next digit (4) of the dividend behind the 14 and repeat the process: 144 / 33

Let's proceed to step 6:
The number 33 fits into 144 4 times, leaving a remainder of 12.
The next digit of our result is 4. 
Result so far: 11914.0
If we take 132 away from 144, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 7:
When dividing 120 by 33, we get 3 with a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 11914.3
If we take 99 away from 120, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 8:
33 goes into 210 6 times with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 11914.36
If we take 198 away from 210, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 9:
120 divided by 33 is 3 with a remainder of 21.
The next digit of our result is 3. 
Result so far: 11914.363
If we subtract 99 from 120, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 10:
The number 33 fits into 210 6 times, leaving a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 11914.3636
Deduct 198 from 210 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 11:
The number 33 fits into 120 3 times, leaving a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 11914.36363
Deduct 99 from 120 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 12:
33 goes into 210 6 times with a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 11914.363636
If we subtract 198 from 210, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 13:
120 divided by 33 is 3 with a remainder of 21.
The next digit of our result is 3. 
Result so far: 11914.3636363
Subtracting 99 from 120 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 14:
210 divided by 33 is 6 with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 11914.36363636
The remainder is 12 after subtracting 198 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 11914.36363636, with a leftover of 1.2e-08.
