We look at the division of 509267 by 42 
We want to figure out the number of times 509267 can be divided by 42.

Advancing to step 1:
42 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 42

Moving on to step 2:
42 can be fit into 50 1 times, resulting in a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 42 from 50 to get 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 42

Moving on to step 3:
When dividing 89 by 42, we get 2 with a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we take 84 away from 89, we end up with 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 42

On to step 4:
The number 42 fits into 52 1 times, leaving a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 121.0
If we take 42 away from 52, we end up with 10.
Include the next digit (6) from the dividend after 10, then repeat: 106 / 42

Step 5:
When dividing 106 by 42, we get 2 with a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 1212.0
If we subtract 84 from 106, we get 22.
Grab the next digit (7) from the dividend, add it to 22, then carry on: 227 / 42

Going ahead to step 6:
When dividing 227 by 42, we get 5 with a remainder of 17.
Use 5 as the next digit of our solution. 
Result so far: 12125.0
Subtract 210 from 227 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 7:
42 can be fit into 170 4 times, resulting in a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 12125.4
Subtracting 168 from 170 leaves us 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.

On to step 8:
20 divided by 42 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 12125.4
Deduct 0 from 20 and we're left 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.

On to step 9:
42 goes into 200 4 times with a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 12125.404
Deduct 168 from 200 and we're left 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 10:
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: 12125.4047
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.

Going ahead to step 11:
260 divided by 42 is 6 with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 12125.40476
Subtract 252 from 260 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.

Step 12:
80 divided by 42 is 1 with a remainder of 38.
Use 1 as the next digit of our solution. 
Result so far: 12125.404761
If we subtract 42 from 80, we get 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 13:
If we divide 380 by 42, we get 9 and a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 12125.4047619
The remainder is 2 after subtracting 378 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 14:
If we divide 20 by 42, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 12125.4047619
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.

Our division results in 12125.4047619 with a remaining 2e-08.
