We divide 42495 by 84
We want to figure out the number of times 42495 can be divided by 84.

Step 1:
4 divided by 84 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 84

Advancing to step 2:
When dividing 42 by 84, we get 0 with a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Take the next digit (4) from the dividend and append it to 42, then repeat: 424 / 84

Advancing to step 3:
84 goes into 424 5 times with a remainder of 4.
Write down 5 as next digit of the result. 
Result so far: 5.0
The remainder is 4 after subtracting 420 from 424.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 84

Step 4:
84 goes into 49 0 times with a remainder of 49.
Put 0 as the next digit of the answer. 
Result so far: 50.0
Subtract 0 from 49 to get 49.
Bring next digit (5) of the dividend behind the 49 and repeat the process: 495 / 84

Going ahead to step 5:
The number 84 fits into 495 5 times, leaving a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 505.0
The remainder is 75 after subtracting 420 from 495.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 6:
When dividing 750 by 84, we get 8 with a remainder of 78.
Put 8 as the next digit of the answer. 
Result so far: 505.8
The remainder is 78 after subtracting 672 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 7:
780 divided by 84 is 9 with a remainder of 24.
Use 9 as the next digit of our solution. 
Result so far: 505.89
If we subtract 756 from 780, 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 8:
When dividing 240 by 84, we get 2 with a remainder of 72.
Record the quotient 2 as the next digit in the result. 
Result so far: 505.892
Subtract 168 from 240 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 9:
The number 84 fits into 720 8 times, leaving a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 505.8928
If we subtract 672 from 720, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 10:
If we divide 480 by 84, we get 5 and a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 505.89285
Subtract 420 from 480 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 11:
The number 84 fits into 600 7 times, leaving a remainder of 12.
Record the quotient 7 as the next digit in the result. 
Result so far: 505.892857
Subtracting 588 from 600 leaves us 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.

Moving on to step 12:
84 can be fit into 120 1 times, resulting in a remainder of 36.
Use 1 as the next digit of our solution. 
Result so far: 505.8928571
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.

Moving on to step 13:
If we divide 360 by 84, we get 4 and a remainder of 24.
The next digit of our result is 4. 
Result so far: 505.89285714
Deduct 336 from 360 and we're left with 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 505.89285714 with a balance of 2.4e-08.
