We divide 42020 by 34
We're looking to find how many times 34 goes into 42020.

Moving on to step 1:
If we divide 4 by 34, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 34

Let's proceed to step 2:
When dividing 42 by 34, we get 1 with a remainder of 8.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 34 from 42 leaves us with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 34

On to step 3:
The number 34 fits into 80 2 times, leaving a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we subtract 68 from 80, we get 12.
Bring next digit (2) of the dividend behind the 12 and repeat the process: 122 / 34

Step 4:
34 goes into 122 3 times with a remainder of 20.
Record the quotient 3 as the next digit in the result. 
Result so far: 123.0
If we subtract 102 from 122, we get 20.
Include the next digit (0) from the dividend after 20, then repeat: 200 / 34

Advancing to step 5:
If we divide 200 by 34, we get 5 and a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 1235.0
If we subtract 170 from 200, 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.

Let's proceed to step 6:
When dividing 300 by 34, we get 8 with a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 1235.8
Subtracting 272 from 300 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 7:
34 can be fit into 280 8 times, resulting in a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 1235.88
Deduct 272 from 280 and we're left with 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 1235.88, with a leftover of 0.008.
