42791 divided by 84 
Let's see how many times 84 fits into 42791.

On to step 1:
The number 84 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 84

Going ahead to step 2:
The number 84 fits into 42 0 times, leaving a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Take the next digit (7) from the dividend and append it to 42, then repeat: 427 / 84

On to step 3:
The number 84 fits into 427 5 times, leaving a remainder of 7.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 420 from 427 to get 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 84

Let's proceed to step 4:
84 can be fit into 79 0 times, resulting in a remainder of 79.
Put 0 as the next digit of the answer. 
Result so far: 50.0
If we subtract 0 from 79, we get 79.
Append the next digit (1) from the dividend to 79 and continue with: 791 / 84

Going ahead to step 5:
When dividing 791 by 84, we get 9 with a remainder of 35.
Put 9 as the next digit of the answer. 
Result so far: 509.0
Subtracting 756 from 791 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 6:
The number 84 fits into 350 4 times, leaving a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 509.4
If we subtract 336 from 350, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 7:
When dividing 140 by 84, we get 1 with a remainder of 56.
The number 1 becomes the next digit in our result. 
Result so far: 509.41
Deduct 84 from 140 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 8:
The number 84 fits into 560 6 times, leaving a remainder of 56.
Write down 6 as next digit of the result. 
Result so far: 509.416
Subtract 504 from 560 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 9:
When dividing 560 by 84, we get 6 with a remainder of 56.
The next digit of our result is 6. 
Result so far: 509.4166
Deduct 504 from 560 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

In conclusion, the division gives 509.4166 with a balance of 0.00056.
