We look at the division of 397595 by 33 
We want to divide 397595 by 33.

Step 1:
If we divide 3 by 33, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 33

Step 2:
33 goes into 39 1 times with a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 33 away from 39, we end up with 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 33

On to step 3:
When dividing 67 by 33, we get 2 with a remainder of 1.
The next digit of our result is 2. 
Result so far: 12.0
The remainder is 1 after subtracting 66 from 67.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 33

Step 4:
If we divide 15 by 33, we get 0 and a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 120.0
If we subtract 0 from 15, we get 15.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 33

On to step 5:
If we divide 159 by 33, we get 4 and a remainder of 27.
Use 4 as the next digit of our solution. 
Result so far: 1204.0
Deduct 132 from 159 and we're left with 27.
Grab the next digit (5) from the dividend, add it to 27, then carry on: 275 / 33

Going ahead to step 6:
When dividing 275 by 33, we get 8 with a remainder of 11.
The number 8 becomes the next digit in our result. 
Result so far: 12048.0
Deduct 264 from 275 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 7:
33 goes into 110 3 times with a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 12048.3
The remainder is 11 after subtracting 99 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 8:
When dividing 110 by 33, we get 3 with a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 12048.33
Subtract 99 from 110 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Our division results in 12048.33 with a remaining 0.011.
