We're dividing 425515 by 42 
Let's see how many times 42 fits into 425515.

Let's proceed to step 1:
The number 42 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 42

Step 2:
42 can be fit into 42 1 times, resulting in a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 42 from 42, we get 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 42

Moving on to step 3:
42 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 42

Let's proceed to step 4:
When dividing 55 by 42, we get 1 with a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 101.0
Deduct 42 from 55 and we're left with 13.
Grab the next digit (1) from the dividend, add it to 13, then carry on: 131 / 42

Moving on to step 5:
42 can be fit into 131 3 times, resulting in a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 1013.0
Deduct 126 from 131 and we're left with 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 42

Moving on to step 6:
The number 42 fits into 55 1 times, leaving a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 10131.0
Deduct 42 from 55 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 7:
If we divide 130 by 42, we get 3 and a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 10131.3
The remainder is 4 after subtracting 126 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 8:
42 goes into 40 0 times with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 10131.3
If we subtract 0 from 40, we 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.

On to step 9:
42 goes into 400 9 times with a remainder of 22.
Use 9 as the next digit of our solution. 
Result so far: 10131.309
The remainder is 22 after subtracting 378 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 10:
42 goes into 220 5 times with a remainder of 10.
The next digit of our result is 5. 
Result so far: 10131.3095
If we take 210 away from 220, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 11:
The number 42 fits into 100 2 times, leaving a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 10131.30952
Subtract 84 from 100 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.

Going ahead to step 12:
42 goes into 160 3 times with a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 10131.309523
Subtracting 126 from 160 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 13:
340 divided by 42 is 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 10131.3095238
If we subtract 336 from 340, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 14:
When dividing 40 by 42, we get 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 10131.3095238
If we subtract 0 from 40, we 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.

The final result is 10131.3095238 with a remainder of 4e-08.
