915315 divided by 42 
We want to divide 915315 by 42.

On to step 1:
9 divided by 42 is 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 42

Let's proceed to step 2:
When dividing 91 by 42, we get 2 with a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 84 from 91 to get 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 42

On to step 3:
When dividing 75 by 42, we get 1 with a remainder of 33.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
The remainder is 33 after subtracting 42 from 75.
Bring next digit (3) of the dividend behind the 33 and repeat the process: 333 / 42

Step 4:
The number 42 fits into 333 7 times, leaving a remainder of 39.
Put 7 as the next digit of the answer. 
Result so far: 217.0
The remainder is 39 after subtracting 294 from 333.
Fetch the next digit (1) from the dividend, attach it to 39 and continue: 391 / 42

On to step 5:
The number 42 fits into 391 9 times, leaving a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 2179.0
If we subtract 378 from 391, we get 13.
Include the next digit (5) from the dividend after 13, then repeat: 135 / 42

Going ahead to step 6:
135 divided by 42 is 3 with a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 21793.0
Subtract 126 from 135 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 7:
The number 42 fits into 90 2 times, leaving a remainder of 6.
The next digit of our result is 2. 
Result so far: 21793.2
If we subtract 84 from 90, we 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.

Going ahead to step 8:
If we divide 60 by 42, we get 1 and a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 21793.21
Deduct 42 from 60 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 9:
The number 42 fits into 180 4 times, leaving a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 21793.214
The remainder is 12 after subtracting 168 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 10:
The number 42 fits into 120 2 times, leaving a remainder of 36.
The next digit of our result is 2. 
Result so far: 21793.2142
Deduct 84 from 120 and we're left 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 11:
If we divide 360 by 42, we get 8 and a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 21793.21428
Subtract 336 from 360 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 12:
The number 42 fits into 240 5 times, leaving a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 21793.214285
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.

Moving on to step 13:
42 can be fit into 300 7 times, resulting in a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 21793.2142857
The remainder is 6 after subtracting 294 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 14:
When dividing 60 by 42, we get 1 with a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 21793.21428571
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.

The final result is 21793.21428571 with a remainder of 1.8e-08.
