We look at the division of 20388 by 79 
Our goal is to divide 20388 by 79.

On to step 1:
2 divided by 79 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 79

Going ahead to step 2:
79 can be fit into 20 0 times, resulting in a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Include the next digit (3) from the dividend after 20, then repeat: 203 / 79

Advancing to step 3:
The number 79 fits into 203 2 times, leaving a remainder of 45.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 158 away from 203, we end up with 45.
Bring next digit (8) of the dividend behind the 45 and repeat the process: 458 / 79

Step 4:
458 divided by 79 is 5 with a remainder of 63.
Write down 5 as next digit of the result. 
Result so far: 25.0
If we subtract 395 from 458, we get 63.
Fetch the next digit (8) from the dividend, attach it to 63 and continue: 638 / 79

Let's proceed to step 5:
79 can be fit into 638 8 times, resulting in a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 258.0
Subtract 632 from 638 to get 6.
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 6:
When dividing 60 by 79, we get 0 with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 258.0
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 7:
79 can be fit into 600 7 times, resulting in a remainder of 47.
The number 7 becomes the next digit in our result. 
Result so far: 258.07
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.

Advancing to step 8:
If we divide 470 by 79, we get 5 and a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 258.075
If we subtract 395 from 470, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 9:
The number 79 fits into 750 9 times, leaving a remainder of 39.
Write down 9 as next digit of the result. 
Result so far: 258.0759
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.

Advancing to step 10:
The number 79 fits into 390 4 times, leaving a remainder of 74.
Write down 4 as next digit of the result. 
Result so far: 258.07594
The remainder is 74 after subtracting 316 from 390.
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 11:
If we divide 740 by 79, we get 9 and a remainder of 29.
Record the quotient 9 as the next digit in the result. 
Result so far: 258.075949
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.

Let's proceed to step 12:
The number 79 fits into 290 3 times, leaving a remainder of 53.
Write down 3 as next digit of the result. 
Result so far: 258.0759493
Deduct 237 from 290 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 13:
When dividing 530 by 79, we get 6 with a remainder of 56.
The next digit of our result is 6. 
Result so far: 258.07594936
If we subtract 474 from 530, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The final outcome is 258.07594936, with a leftover of 5.6e-08.
