We look at the division of 307915 by 42 
We want to figure out the number of times 307915 can be divided by 42.

Let's proceed to step 1:
The number 42 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 42

Moving on to step 2:
30 divided by 42 is 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Grab the next digit (7) from the dividend, add it to 30, then carry on: 307 / 42

Let's proceed to step 3:
42 can be fit into 307 7 times, resulting in a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
The remainder is 13 after subtracting 294 from 307.
Append the next digit (9) from the dividend to 13 and continue with: 139 / 42

Advancing to step 4:
If we divide 139 by 42, we get 3 and a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 73.0
Deduct 126 from 139 and we're left with 13.
Include the next digit (1) from the dividend after 13, then repeat: 131 / 42

On to step 5:
If we divide 131 by 42, we get 3 and a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 733.0
Subtract 126 from 131 to get 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 42

Let's proceed to step 6:
55 divided by 42 is 1 with a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 7331.0
The remainder is 13 after subtracting 42 from 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 7:
42 goes into 130 3 times with a remainder of 4.
The next digit of our result is 3. 
Result so far: 7331.3
If we take 126 away from 130, we end up 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.

Advancing to step 8:
The number 42 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 7331.3
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.
The next digit of our result is 9. 
Result so far: 7331.309
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.

On to step 10:
220 divided by 42 is 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 7331.3095
Subtracting 210 from 220 leaves us 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.

Let's proceed to step 11:
If we divide 100 by 42, we get 2 and a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 7331.30952
Subtracting 84 from 100 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 12:
160 divided by 42 is 3 with a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 7331.309523
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.

Step 13:
When dividing 340 by 42, we get 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 7331.3095238
If we take 336 away from 340, we end up 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.

Advancing to step 14:
42 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 7331.3095238
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

In conclusion, the division gives 7331.3095238 with a balance of 4e-08.
