We look at the division of 79721 by 84 
Let's see how many times 84 fits into 79721.

Let's proceed to step 1:
If we divide 7 by 84, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 84

Going ahead to step 2:
79 divided by 84 is 0 with a remainder of 79.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 79 and we're left with 79.
Include the next digit (7) from the dividend after 79, then repeat: 797 / 84

On to step 3:
If we divide 797 by 84, we get 9 and a remainder of 41.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Deduct 756 from 797 and we're left with 41.
Grab the next digit (2) from the dividend, add it to 41, then carry on: 412 / 84

Step 4:
84 goes into 412 4 times with a remainder of 76.
Record the quotient 4 as the next digit in the result. 
Result so far: 94.0
Subtracting 336 from 412 leaves us with 76.
Append the next digit (1) from the dividend to 76 and continue with: 761 / 84

Moving on to step 5:
If we divide 761 by 84, we get 9 and a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 949.0
If we subtract 756 from 761, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 6:
When dividing 50 by 84, we get 0 with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 949.0
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 7:
If we divide 500 by 84, we get 5 and a remainder of 80.
Put 5 as the next digit of the answer. 
Result so far: 949.05
Subtracting 420 from 500 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 8:
The number 84 fits into 800 9 times, leaving a remainder of 44.
Write down 9 as next digit of the result. 
Result so far: 949.059
Subtracting 756 from 800 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 9:
If we divide 440 by 84, we get 5 and a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 949.0595
Subtract 420 from 440 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 10:
84 can be fit into 200 2 times, resulting in a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 949.05952
The remainder is 32 after subtracting 168 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 11:
When dividing 320 by 84, we get 3 with a remainder of 68.
Record the quotient 3 as the next digit in the result. 
Result so far: 949.059523
If we take 252 away from 320, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 12:
If we divide 680 by 84, we get 8 and a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 949.0595238
The remainder is 8 after subtracting 672 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 13:
When dividing 80 by 84, we get 0 with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 949.0595238
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Our division results in 949.0595238 with a remaining 8e-08.
