We're dividing 39015 by 79 
Let's see how many times 79 fits into 39015.

Let's proceed to step 1:
If we divide 3 by 79, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 79

Moving on to step 2:
When dividing 39 by 79, we get 0 with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Grab the next digit (0) from the dividend, add it to 39, then carry on: 390 / 79

On to step 3:
When dividing 390 by 79, we get 4 with a remainder of 74.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 74 after subtracting 316 from 390.
Grab the next digit (1) from the dividend, add it to 74, then carry on: 741 / 79

Moving on to step 4:
If we divide 741 by 79, we get 9 and a remainder of 30.
Put 9 as the next digit of the answer. 
Result so far: 49.0
The remainder is 30 after subtracting 711 from 741.
Take the next digit (5) from the dividend and append it to 30, then repeat: 305 / 79

On to step 5:
79 can be fit into 305 3 times, resulting in a remainder of 68.
Write down 3 as next digit of the result. 
Result so far: 493.0
Subtract 237 from 305 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 6:
79 can be fit into 680 8 times, resulting in a remainder of 48.
The next digit of our result is 8. 
Result so far: 493.8
The remainder is 48 after subtracting 632 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 7:
When dividing 480 by 79, we get 6 with a remainder of 6.
The next digit of our result is 6. 
Result so far: 493.86
The remainder is 6 after subtracting 474 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 8:
When dividing 60 by 79, we get 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 493.86
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 9:
79 can be fit into 600 7 times, resulting in a remainder of 47.
The next digit of our result is 7. 
Result so far: 493.8607
If we subtract 553 from 600, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 10:
If we divide 470 by 79, we get 5 and a remainder of 75.
The next digit of our result is 5. 
Result so far: 493.86075
If we take 395 away from 470, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 11:
When dividing 750 by 79, we get 9 with a remainder of 39.
The number 9 becomes the next digit in our result. 
Result so far: 493.860759
If we take 711 away from 750, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 12:
The number 79 fits into 390 4 times, leaving a remainder of 74.
Put 4 as the next digit of the answer. 
Result so far: 493.8607594
If we take 316 away from 390, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 13:
79 can be fit into 740 9 times, resulting in a remainder of 29.
The number 9 becomes the next digit in our result. 
Result so far: 493.86075949
Subtracting 711 from 740 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

The final result is 493.86075949 with a remainder of 2.9e-08.
