517708 divided by 42 
Let's see how many times 42 fits into 517708.

Advancing to step 1:
42 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 42

Going ahead to step 2:
42 can be fit into 51 1 times, resulting in a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 42 from 51, we get 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 42

Moving on to step 3:
If we divide 97 by 42, we get 2 and a remainder of 13.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we subtract 84 from 97, we get 13.
Fetch the next digit (7) from the dividend, attach it to 13 and continue: 137 / 42

Advancing to step 4:
The number 42 fits into 137 3 times, leaving a remainder of 11.
The next digit of our result is 3. 
Result so far: 123.0
Deduct 126 from 137 and we're left with 11.
Fetch the next digit (0) from the dividend, attach it to 11 and continue: 110 / 42

Advancing to step 5:
42 goes into 110 2 times with a remainder of 26.
Put 2 as the next digit of the answer. 
Result so far: 1232.0
The remainder is 26 after subtracting 84 from 110.
Bring next digit (8) of the dividend behind the 26 and repeat the process: 268 / 42

Step 6:
When dividing 268 by 42, we get 6 with a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 12326.0
If we take 252 away from 268, we end up 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.

Going ahead to step 7:
If we divide 160 by 42, we get 3 and a remainder of 34.
Record the quotient 3 as the next digit in the result. 
Result so far: 12326.3
The remainder is 34 after subtracting 126 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 8:
If we divide 340 by 42, we get 8 and a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 12326.38
Deduct 336 from 340 and we're left 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.

Moving on to step 9:
The number 42 fits into 40 0 times, leaving a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 12326.38
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.

Let's proceed to step 10:
42 can be fit into 400 9 times, resulting in a remainder of 22.
The next digit of our result is 9. 
Result so far: 12326.3809
Subtracting 378 from 400 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 11:
42 goes into 220 5 times with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 12326.38095
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.

Step 12:
42 goes into 100 2 times with a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 12326.380952
Deduct 84 from 100 and we're left 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.

Going ahead to step 13:
When dividing 160 by 42, we get 3 with a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 12326.3809523
The remainder is 34 after subtracting 126 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 14:
340 divided by 42 is 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 12326.38095238
Subtracting 336 from 340 leaves us 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.

Our division results in 12326.38095238 with a remaining 4e-09.
