We look at the division of 179423 by 42 
Let's see how many times 42 fits into 179423.

Going ahead to step 1:
When dividing 1 by 42, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 42

Step 2:
The number 42 fits into 17 0 times, leaving a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Take the next digit (9) from the dividend and append it to 17, then repeat: 179 / 42

Going ahead to step 3:
179 divided by 42 is 4 with a remainder of 11.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 11 after subtracting 168 from 179.
Bring next digit (4) of the dividend behind the 11 and repeat the process: 114 / 42

Let's proceed to step 4:
The number 42 fits into 114 2 times, leaving a remainder of 30.
Put 2 as the next digit of the answer. 
Result so far: 42.0
Subtracting 84 from 114 leaves us with 30.
Append the next digit (2) from the dividend to 30 and continue with: 302 / 42

On to step 5:
The number 42 fits into 302 7 times, leaving a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 427.0
Deduct 294 from 302 and we're left with 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 42

Going ahead to step 6:
83 divided by 42 is 1 with a remainder of 41.
Write down 1 as next digit of the result. 
Result so far: 4271.0
If we take 42 away from 83, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 7:
42 goes into 410 9 times with a remainder of 32.
Put 9 as the next digit of the answer. 
Result so far: 4271.9
If we subtract 378 from 410, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 8:
When dividing 320 by 42, we get 7 with a remainder of 26.
Write down 7 as next digit of the result. 
Result so far: 4271.97
The remainder is 26 after subtracting 294 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 9:
The number 42 fits into 260 6 times, leaving a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 4271.976
The remainder is 8 after subtracting 252 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 10:
42 can be fit into 80 1 times, resulting in a remainder of 38.
Use 1 as the next digit of our solution. 
Result so far: 4271.9761
Subtracting 42 from 80 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 11:
If we divide 380 by 42, we get 9 and a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 4271.97619
If we take 378 away from 380, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 12:
20 divided by 42 is 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 4271.97619
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 13:
If we divide 200 by 42, we get 4 and a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 4271.9761904
If we subtract 168 from 200, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 14:
The number 42 fits into 320 7 times, leaving a remainder of 26.
Use 7 as the next digit of our solution. 
Result so far: 4271.97619047
Deduct 294 from 320 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Our division results in 4271.97619047 with a remaining 2.6e-08.
