We look at the division of 205179 by 42 
We're looking to find how many times 42 goes into 205179.

Step 1:
2 divided by 42 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 42

Moving on to step 2:
20 divided by 42 is 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Take the next digit (5) from the dividend and append it to 20, then repeat: 205 / 42

On to step 3:
The number 42 fits into 205 4 times, leaving a remainder of 37.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 168 from 205 to get 37.
Fetch the next digit (1) from the dividend, attach it to 37 and continue: 371 / 42

Moving on to step 4:
42 can be fit into 371 8 times, resulting in a remainder of 35.
Use 8 as the next digit of our solution. 
Result so far: 48.0
If we take 336 away from 371, we end up with 35.
Take the next digit (7) from the dividend and append it to 35, then repeat: 357 / 42

Advancing to step 5:
42 goes into 357 8 times with a remainder of 21.
Use 8 as the next digit of our solution. 
Result so far: 488.0
If we take 336 away from 357, we end up with 21.
Fetch the next digit (9) from the dividend, attach it to 21 and continue: 219 / 42

Moving on to step 6:
42 can be fit into 219 5 times, resulting in a remainder of 9.
The next digit of our result is 5. 
Result so far: 4885.0
If we take 210 away from 219, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
42 can be fit into 90 2 times, resulting in a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 4885.2
The remainder is 6 after subtracting 84 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 8:
42 goes into 60 1 times with a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 4885.21
The remainder is 18 after subtracting 42 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 9:
If we divide 180 by 42, we get 4 and a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 4885.214
Deduct 168 from 180 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 10:
42 goes into 120 2 times with a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 4885.2142
The remainder is 36 after subtracting 84 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 11:
42 can be fit into 360 8 times, resulting in a remainder of 24.
The next digit of our result is 8. 
Result so far: 4885.21428
If we subtract 336 from 360, we 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.

Advancing to step 12:
The number 42 fits into 240 5 times, leaving a remainder of 30.
The next digit of our result is 5. 
Result so far: 4885.214285
If we subtract 210 from 240, 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.

On to step 13:
42 goes into 300 7 times with a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 4885.2142857
Subtracting 294 from 300 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 14:
The number 42 fits into 60 1 times, leaving a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 4885.21428571
The remainder is 18 after subtracting 42 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

After the division, we end up with 4885.21428571 and a remainder of 1.8e-08.
