We look at the division of 239966 by 79 
We want to figure out the number of times 239966 can be divided by 79.

Let's proceed to step 1:
2 divided by 79 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 79

Moving on to step 2:
If we divide 23 by 79, we get 0 and a remainder of 23.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 23, we end up with 23.
Take the next digit (9) from the dividend and append it to 23, then repeat: 239 / 79

On to step 3:
When dividing 239 by 79, we get 3 with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 237 from 239, we get 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 79

Let's proceed to step 4:
If we divide 29 by 79, we get 0 and a remainder of 29.
Use 0 as the next digit of our solution. 
Result so far: 30.0
Subtracting 0 from 29 leaves us with 29.
Include the next digit (6) from the dividend after 29, then repeat: 296 / 79

Going ahead to step 5:
79 goes into 296 3 times with a remainder of 59.
The next digit of our result is 3. 
Result so far: 303.0
Deduct 237 from 296 and we're left with 59.
Append the next digit (6) from the dividend to 59 and continue with: 596 / 79

On to step 6:
If we divide 596 by 79, we get 7 and a remainder of 43.
Use 7 as the next digit of our solution. 
Result so far: 3037.0
If we subtract 553 from 596, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 7:
79 can be fit into 430 5 times, resulting in a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 3037.5
If we take 395 away from 430, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 8:
If we divide 350 by 79, we get 4 and a remainder of 34.
The next digit of our result is 4. 
Result so far: 3037.54
If we subtract 316 from 350, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 9:
When dividing 340 by 79, we get 4 with a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 3037.544
The remainder is 24 after subtracting 316 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The quotient of the division is 3037.544, and the remainder is 0.0024.
