We look at the division of 519495 by 42 
We're looking to find how many times 42 goes into 519495.

On to step 1:
When dividing 5 by 42, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 42

Step 2:
If we divide 51 by 42, we get 1 and a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 42 from 51 to get 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 42

Let's proceed to step 3:
The number 42 fits into 99 2 times, leaving a remainder of 15.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we subtract 84 from 99, we get 15.
Include the next digit (4) from the dividend after 15, then repeat: 154 / 42

Let's proceed to step 4:
154 divided by 42 is 3 with a remainder of 28.
Record the quotient 3 as the next digit in the result. 
Result so far: 123.0
Subtract 126 from 154 to get 28.
Take the next digit (9) from the dividend and append it to 28, then repeat: 289 / 42

Let's proceed to step 5:
42 goes into 289 6 times with a remainder of 37.
The number 6 becomes the next digit in our result. 
Result so far: 1236.0
If we take 252 away from 289, we end up with 37.
Bring next digit (5) of the dividend behind the 37 and repeat the process: 375 / 42

On to step 6:
42 can be fit into 375 8 times, resulting in a remainder of 39.
Put 8 as the next digit of the answer. 
Result so far: 12368.0
If we subtract 336 from 375, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 7:
390 divided by 42 is 9 with a remainder of 12.
Write down 9 as next digit of the result. 
Result so far: 12368.9
Subtracting 378 from 390 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 8:
120 divided by 42 is 2 with a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 12368.92
If we take 84 away from 120, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 9:
When dividing 360 by 42, we get 8 with a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 12368.928
Deduct 336 from 360 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 10:
If we divide 240 by 42, we get 5 and a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 12368.9285
Deduct 210 from 240 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.

Advancing to step 11:
300 divided by 42 is 7 with a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 12368.92857
Subtract 294 from 300 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 12:
60 divided by 42 is 1 with a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 12368.928571
If we subtract 42 from 60, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 13:
42 can be fit into 180 4 times, resulting in a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 12368.9285714
Deduct 168 from 180 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 14:
42 goes into 120 2 times with a remainder of 36.
The next digit of our result is 2. 
Result so far: 12368.92857142
Subtracting 84 from 120 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Our division results in 12368.92857142 with a remaining 3.6e-08.
