We look at the division of 393258 by 79 
Let's see how many times 79 fits into 393258.

Moving on to step 1:
79 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 79

Step 2:
The number 79 fits into 39 0 times, leaving a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Include the next digit (3) from the dividend after 39, then repeat: 393 / 79

Let's proceed to step 3:
When dividing 393 by 79, we get 4 with a remainder of 77.
The next digit of our result is 4. 
Result so far: 4.0
If we take 316 away from 393, we end up with 77.
Append the next digit (2) from the dividend to 77 and continue with: 772 / 79

On to step 4:
When dividing 772 by 79, we get 9 with a remainder of 61.
Use 9 as the next digit of our solution. 
Result so far: 49.0
Deduct 711 from 772 and we're left with 61.
Include the next digit (5) from the dividend after 61, then repeat: 615 / 79

On to step 5:
615 divided by 79 is 7 with a remainder of 62.
Record the quotient 7 as the next digit in the result. 
Result so far: 497.0
Subtract 553 from 615 to get 62.
Bring next digit (8) of the dividend behind the 62 and repeat the process: 628 / 79

On to step 6:
When dividing 628 by 79, we get 7 with a remainder of 75.
Write down 7 as next digit of the result. 
Result so far: 4977.0
If we take 553 away from 628, 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.

Going ahead to step 7:
When dividing 750 by 79, we get 9 with a remainder of 39.
Record the quotient 9 as the next digit in the result. 
Result so far: 4977.9
Deduct 711 from 750 and we're left 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.

Step 8:
79 can be fit into 390 4 times, resulting in a remainder of 74.
Put 4 as the next digit of the answer. 
Result so far: 4977.94
Deduct 316 from 390 and we're left 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.

On to step 9:
When dividing 740 by 79, we get 9 with a remainder of 29.
Use 9 as the next digit of our solution. 
Result so far: 4977.949
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.

Moving on to step 10:
The number 79 fits into 290 3 times, leaving a remainder of 53.
Use 3 as the next digit of our solution. 
Result so far: 4977.9493
The remainder is 53 after subtracting 237 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 11:
79 goes into 530 6 times with a remainder of 56.
Record the quotient 6 as the next digit in the result. 
Result so far: 4977.94936
If we take 474 away from 530, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 12:
560 divided by 79 is 7 with a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 4977.949367
If we take 553 away from 560, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 13:
79 goes into 70 0 times with a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 4977.949367
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 14:
If we divide 700 by 79, we get 8 and a remainder of 68.
The number 8 becomes the next digit in our result. 
Result so far: 4977.94936708
Subtracting 632 from 700 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

The final result is 4977.94936708 with a remainder of 6.8e-08.
