We look at the division of 142412 by 34 
Let's see how many times 34 fits into 142412.

Let's proceed to step 1:
34 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 34

Step 2:
When dividing 14 by 34, we get 0 with a remainder of 14.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 14 to get 14.
Grab the next digit (2) from the dividend, add it to 14, then carry on: 142 / 34

Going ahead to step 3:
If we divide 142 by 34, we get 4 and a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 136 from 142, we get 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 34

Advancing to step 4:
64 divided by 34 is 1 with a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 41.0
Subtract 34 from 64 to get 30.
Bring next digit (1) of the dividend behind the 30 and repeat the process: 301 / 34

Advancing to step 5:
If we divide 301 by 34, we get 8 and a remainder of 29.
The number 8 becomes the next digit in our result. 
Result so far: 418.0
The remainder is 29 after subtracting 272 from 301.
Bring next digit (2) of the dividend behind the 29 and repeat the process: 292 / 34

Going ahead to step 6:
34 can be fit into 292 8 times, resulting in a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 4188.0
If we take 272 away from 292, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 7:
The number 34 fits into 200 5 times, leaving a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 4188.5
Deduct 170 from 200 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 8:
If we divide 300 by 34, we get 8 and a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 4188.58
Subtract 272 from 300 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 9:
34 can be fit into 280 8 times, resulting in a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 4188.588
Subtract 272 from 280 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 4188.588, with a leftover of 0.0008.
