We're dividing 721780 by 84 
We're looking to find how many times 84 goes into 721780.

Moving on to step 1:
The number 84 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 84

Going ahead to step 2:
84 goes into 72 0 times with a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 72 after subtracting 0 from 72.
Bring next digit (1) of the dividend behind the 72 and repeat the process: 721 / 84

Going ahead to step 3:
When dividing 721 by 84, we get 8 with a remainder of 49.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 672 from 721, we get 49.
Grab the next digit (7) from the dividend, add it to 49, then carry on: 497 / 84

Advancing to step 4:
84 goes into 497 5 times with a remainder of 77.
Write down 5 as next digit of the result. 
Result so far: 85.0
Deduct 420 from 497 and we're left with 77.
Append the next digit (8) from the dividend to 77 and continue with: 778 / 84

Step 5:
778 divided by 84 is 9 with a remainder of 22.
The number 9 becomes the next digit in our result. 
Result so far: 859.0
Subtracting 756 from 778 leaves us with 22.
Bring next digit (0) of the dividend behind the 22 and repeat the process: 220 / 84

Let's proceed to step 6:
If we divide 220 by 84, we get 2 and a remainder of 52.
Record the quotient 2 as the next digit in the result. 
Result so far: 8592.0
If we take 168 away from 220, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 7:
When dividing 520 by 84, we get 6 with a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 8592.6
Subtracting 504 from 520 leaves us 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.

Advancing to step 8:
If we divide 160 by 84, we get 1 and a remainder of 76.
Use 1 as the next digit of our solution. 
Result so far: 8592.61
If we take 84 away from 160, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 9:
84 goes into 760 9 times with a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 8592.619
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.

Step 10:
The number 84 fits into 40 0 times, leaving a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 8592.619
Deduct 0 from 40 and we're left 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 11:
When dividing 400 by 84, we get 4 with a remainder of 64.
Record the quotient 4 as the next digit in the result. 
Result so far: 8592.61904
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 12:
84 goes into 640 7 times with a remainder of 52.
The number 7 becomes the next digit in our result. 
Result so far: 8592.619047
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.

Step 13:
If we divide 520 by 84, we get 6 and a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 8592.6190476
If we take 504 away from 520, we end up 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.

Let's proceed to step 14:
160 divided by 84 is 1 with a remainder of 76.
Use 1 as the next digit of our solution. 
Result so far: 8592.61904761
The remainder is 76 after subtracting 84 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

In conclusion, the division gives 8592.61904761 with a balance of 7.6e-08.
