We divide 42979 by 84
We want to figure out the number of times 42979 can be divided by 84.

Step 1:
4 divided by 84 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 84

Going ahead to step 2:
If we divide 42 by 84, we get 0 and a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Take the next digit (9) from the dividend and append it to 42, then repeat: 429 / 84

Going ahead to step 3:
84 goes into 429 5 times with a remainder of 9.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we take 420 away from 429, we end up with 9.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 84

Going ahead to step 4:
84 goes into 97 1 times with a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 51.0
Deduct 84 from 97 and we're left with 13.
Bring next digit (9) of the dividend behind the 13 and repeat the process: 139 / 84

Advancing to step 5:
84 can be fit into 139 1 times, resulting in a remainder of 55.
Put 1 as the next digit of the answer. 
Result so far: 511.0
Subtract 84 from 139 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 6:
When dividing 550 by 84, we get 6 with a remainder of 46.
Use 6 as the next digit of our solution. 
Result so far: 511.6
If we take 504 away from 550, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 7:
84 can be fit into 460 5 times, resulting in a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 511.65
Subtracting 420 from 460 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 8:
400 divided by 84 is 4 with a remainder of 64.
Record the quotient 4 as the next digit in the result. 
Result so far: 511.654
Deduct 336 from 400 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 9:
640 divided by 84 is 7 with a remainder of 52.
The number 7 becomes the next digit in our result. 
Result so far: 511.6547
If we subtract 588 from 640, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 10:
The number 84 fits into 520 6 times, leaving a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 511.65476
Deduct 504 from 520 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.

Moving on to step 11:
84 can be fit into 160 1 times, resulting in a remainder of 76.
Put 1 as the next digit of the answer. 
Result so far: 511.654761
Subtract 84 from 160 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 12:
The number 84 fits into 760 9 times, leaving a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 511.6547619
If we take 756 away from 760, we end up 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.

On to step 13:
84 can be fit into 40 0 times, resulting in a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 511.6547619
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The quotient of the division is 511.6547619, and the remainder is 4e-08.
