Let's divide 34124 by 42
Let's see how many times 42 fits into 34124.

On to step 1:
The number 42 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 42

Let's proceed to step 2:
When dividing 34 by 42, we get 0 with a remainder of 34.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 34 after subtracting 0 from 34.
Append the next digit (1) from the dividend to 34 and continue with: 341 / 42

Going ahead to step 3:
42 goes into 341 8 times with a remainder of 5.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 336 from 341 leaves us with 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 42

Moving on to step 4:
42 can be fit into 52 1 times, resulting in a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 81.0
The remainder is 10 after subtracting 42 from 52.
Grab the next digit (4) from the dividend, add it to 10, then carry on: 104 / 42

Let's proceed to step 5:
42 goes into 104 2 times with a remainder of 20.
The next digit of our result is 2. 
Result so far: 812.0
If we take 84 away from 104, 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.

Advancing to step 6:
42 can be fit into 200 4 times, resulting in a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 812.4
The remainder is 32 after subtracting 168 from 200.
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 7:
42 can be fit into 320 7 times, resulting in a remainder of 26.
Write down 7 as next digit of the result. 
Result so far: 812.47
Subtract 294 from 320 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 8:
The number 42 fits into 260 6 times, leaving a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 812.476
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.

Advancing to step 9:
The number 42 fits into 80 1 times, leaving a remainder of 38.
Write down 1 as next digit of the result. 
Result so far: 812.4761
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.

Let's proceed to step 10:
42 can be fit into 380 9 times, resulting in a remainder of 2.
The next digit of our result is 9. 
Result so far: 812.47619
Subtract 378 from 380 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 11:
When dividing 20 by 42, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 812.47619
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.

On to step 12:
42 can be fit into 200 4 times, resulting in a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 812.4761904
Subtracting 168 from 200 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 13:
When dividing 320 by 42, we get 7 with a remainder of 26.
Use 7 as the next digit of our solution. 
Result so far: 812.47619047
If we subtract 294 from 320, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The final outcome is 812.47619047, with a leftover of 2.6e-08.
