We're dividing 508846 by 42 
Our goal is to divide 508846 by 42.

Step 1:
The number 42 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 42

Moving on to step 2:
50 divided by 42 is 1 with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 8 after subtracting 42 from 50.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 42

Going ahead to step 3:
The number 42 fits into 88 2 times, leaving a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 12.0
The remainder is 4 after subtracting 84 from 88.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 42

Let's proceed to step 4:
42 can be fit into 48 1 times, resulting in a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 121.0
If we take 42 away from 48, we end up with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 42

Step 5:
When dividing 64 by 42, we get 1 with a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 1211.0
Subtract 42 from 64 to get 22.
Include the next digit (6) from the dividend after 22, then repeat: 226 / 42

Let's proceed to step 6:
42 goes into 226 5 times with a remainder of 16.
The next digit of our result is 5. 
Result so far: 12115.0
Subtract 210 from 226 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 7:
If we divide 160 by 42, we get 3 and a remainder of 34.
The next digit of our result is 3. 
Result so far: 12115.3
Subtract 126 from 160 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 8:
42 can be fit into 340 8 times, resulting in a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 12115.38
The remainder is 4 after subtracting 336 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
42 can be fit into 40 0 times, resulting in a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 12115.38
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 10:
42 can be fit into 400 9 times, resulting in a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 12115.3809
If we take 378 away from 400, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 11:
42 can be fit into 220 5 times, resulting in a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 12115.38095
The remainder is 10 after subtracting 210 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 12:
42 can be fit into 100 2 times, resulting in a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 12115.380952
The remainder is 16 after subtracting 84 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 13:
160 divided by 42 is 3 with a remainder of 34.
The number 3 becomes the next digit in our result. 
Result so far: 12115.3809523
Subtract 126 from 160 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 14:
When dividing 340 by 42, we get 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 12115.38095238
Subtracting 336 from 340 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 12115.38095238, with a leftover of 4e-09.
