We're dividing 40392 by 93 
Let's see how many times 93 fits into 40392.

Advancing to step 1:
4 divided by 93 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 93

Going ahead to step 2:
93 can be fit into 40 0 times, resulting in a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Grab the next digit (3) from the dividend, add it to 40, then carry on: 403 / 93

Step 3:
When dividing 403 by 93, we get 4 with a remainder of 31.
The next digit of our result is 4. 
Result so far: 4.0
If we take 372 away from 403, we end up with 31.
Append the next digit (9) from the dividend to 31 and continue with: 319 / 93

Let's proceed to step 4:
93 goes into 319 3 times with a remainder of 40.
Write down 3 as next digit of the result. 
Result so far: 43.0
If we subtract 279 from 319, we get 40.
Append the next digit (2) from the dividend to 40 and continue with: 402 / 93

Going ahead to step 5:
The number 93 fits into 402 4 times, leaving a remainder of 30.
Record the quotient 4 as the next digit in the result. 
Result so far: 434.0
If we subtract 372 from 402, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 6:
The number 93 fits into 300 3 times, leaving a remainder of 21.
The next digit of our result is 3. 
Result so far: 434.3
The remainder is 21 after subtracting 279 from 300.
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 7:
The number 93 fits into 210 2 times, leaving a remainder of 24.
The next digit of our result is 2. 
Result so far: 434.32
Subtract 186 from 210 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 8:
93 goes into 240 2 times with a remainder of 54.
The number 2 becomes the next digit in our result. 
Result so far: 434.322
Deduct 186 from 240 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The final outcome is 434.322, with a leftover of 0.0054.
