495945 divided by 42 
We're looking to find how many times 42 goes into 495945.

Let's proceed to step 1:
The number 42 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 42

Let's proceed to step 2:
42 goes into 49 1 times with a remainder of 7.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 7 after subtracting 42 from 49.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 42

Let's proceed to step 3:
42 goes into 75 1 times with a remainder of 33.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
The remainder is 33 after subtracting 42 from 75.
Bring next digit (9) of the dividend behind the 33 and repeat the process: 339 / 42

Let's proceed to step 4:
42 can be fit into 339 8 times, resulting in a remainder of 3.
Record the quotient 8 as the next digit in the result. 
Result so far: 118.0
If we subtract 336 from 339, we get 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 42

Moving on to step 5:
The number 42 fits into 34 0 times, leaving a remainder of 34.
Use 0 as the next digit of our solution. 
Result so far: 1180.0
Deduct 0 from 34 and we're left with 34.
Fetch the next digit (5) from the dividend, attach it to 34 and continue: 345 / 42

Advancing to step 6:
42 can be fit into 345 8 times, resulting in a remainder of 9.
The next digit of our result is 8. 
Result so far: 11808.0
If we take 336 away from 345, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
If we divide 90 by 42, we get 2 and a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 11808.2
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.

Advancing 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: 11808.21
Subtract 42 from 60 to 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.

Step 9:
180 divided by 42 is 4 with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 11808.214
Deduct 168 from 180 and we're left with 12.
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:
42 goes into 120 2 times with a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 11808.2142
If we take 84 away from 120, we end up 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.
The next digit of our result is 8. 
Result so far: 11808.21428
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.

Going ahead to step 12:
42 goes into 240 5 times with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 11808.214285
Subtract 210 from 240 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 13:
42 goes into 300 7 times with a remainder of 6.
The next digit of our result is 7. 
Result so far: 11808.2142857
Subtract 294 from 300 to 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 14:
60 divided by 42 is 1 with a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 11808.21428571
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.

The final outcome is 11808.21428571, with a leftover of 1.8e-08.
