We're dividing 815279 by 42 
We're looking to find how many times 42 goes into 815279.

Let's proceed to step 1:
If we divide 8 by 42, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 42

Step 2:
81 divided by 42 is 1 with a remainder of 39.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 42 from 81 leaves us with 39.
Include the next digit (5) from the dividend after 39, then repeat: 395 / 42

Advancing to step 3:
42 can be fit into 395 9 times, resulting in a remainder of 17.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Subtracting 378 from 395 leaves us with 17.
Fetch the next digit (2) from the dividend, attach it to 17 and continue: 172 / 42

Going ahead to step 4:
The number 42 fits into 172 4 times, leaving a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 194.0
Deduct 168 from 172 and we're left with 4.
Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 42

Advancing to step 5:
42 goes into 47 1 times with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 1941.0
Deduct 42 from 47 and we're left with 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 42

Let's proceed to step 6:
59 divided by 42 is 1 with a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 19411.0
Subtract 42 from 59 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.

Moving on to step 7:
42 goes into 170 4 times with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 19411.4
Subtract 168 from 170 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.

Step 8:
42 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 19411.4
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.

Let's proceed to step 9:
200 divided by 42 is 4 with a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 19411.404
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.

Step 10:
320 divided by 42 is 7 with a remainder of 26.
Write down 7 as next digit of the result. 
Result so far: 19411.4047
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.

Advancing to step 11:
260 divided by 42 is 6 with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 19411.40476
If we take 252 away from 260, we end up 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.

Moving on to step 12:
If we divide 80 by 42, we get 1 and a remainder of 38.
Use 1 as the next digit of our solution. 
Result so far: 19411.404761
Subtract 42 from 80 to 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.

Let's proceed to step 13:
42 goes into 380 9 times with a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 19411.4047619
If we take 378 away from 380, we end up 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.

Going ahead to step 14:
42 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 19411.4047619
If we subtract 0 from 20, we 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.

The final result is 19411.4047619 with a remainder of 2e-08.
