Let's divide 518376 by 42
Let's see how many times 42 fits into 518376.

On to step 1:
If we divide 5 by 42, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 42

On to step 2:
When dividing 51 by 42, we get 1 with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 9 after subtracting 42 from 51.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 42

Going ahead to step 3:
42 can be fit into 98 2 times, resulting in a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
The remainder is 14 after subtracting 84 from 98.
Append the next digit (3) from the dividend to 14 and continue with: 143 / 42

Advancing to step 4:
143 divided by 42 is 3 with a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 123.0
If we take 126 away from 143, we end up with 17.
Include the next digit (7) from the dividend after 17, then repeat: 177 / 42

Let's proceed to step 5:
If we divide 177 by 42, we get 4 and a remainder of 9.
Put 4 as the next digit of the answer. 
Result so far: 1234.0
If we take 168 away from 177, we end up with 9.
Bring next digit (6) of the dividend behind the 9 and repeat the process: 96 / 42

Advancing to step 6:
42 can be fit into 96 2 times, resulting in a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 12342.0
If we subtract 84 from 96, we get 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 7:
120 divided by 42 is 2 with a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 12342.2
Subtract 84 from 120 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 8:
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: 12342.28
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.

Going ahead to step 9:
If we divide 240 by 42, we get 5 and a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 12342.285
The remainder is 30 after subtracting 210 from 240.
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 10:
42 goes into 300 7 times with a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 12342.2857
If we take 294 away from 300, we end up with 6.
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 11:
42 can be fit into 60 1 times, resulting in a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 12342.28571
Subtracting 42 from 60 leaves us 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.

Moving on to step 12:
180 divided by 42 is 4 with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 12342.285714
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.

Going ahead to step 13:
42 goes into 120 2 times with a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 12342.2857142
Subtract 84 from 120 to get 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 14:
42 can be fit into 360 8 times, resulting in a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 12342.28571428
If we subtract 336 from 360, we 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.

In conclusion, the division gives 12342.28571428 with a balance of 2.4e-08.
