Let's divide 721519 by 84
We're looking to find how many times 84 goes into 721519.

Going ahead to step 1:
When dividing 7 by 84, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 84

Moving on to step 2:
The number 84 fits into 72 0 times, leaving a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Include the next digit (1) from the dividend after 72, then repeat: 721 / 84

Step 3:
84 goes into 721 8 times with a remainder of 49.
The next digit of our result is 8. 
Result so far: 8.0
The remainder is 49 after subtracting 672 from 721.
Fetch the next digit (5) from the dividend, attach it to 49 and continue: 495 / 84

On to step 4:
495 divided by 84 is 5 with a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 85.0
The remainder is 75 after subtracting 420 from 495.
Grab the next digit (1) from the dividend, add it to 75, then carry on: 751 / 84

Going ahead to step 5:
When dividing 751 by 84, we get 8 with a remainder of 79.
Write down 8 as next digit of the result. 
Result so far: 858.0
If we take 672 away from 751, we end up with 79.
Fetch the next digit (9) from the dividend, attach it to 79 and continue: 799 / 84

On to step 6:
799 divided by 84 is 9 with a remainder of 43.
The next digit of our result is 9. 
Result so far: 8589.0
Subtracting 756 from 799 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 7:
When dividing 430 by 84, we get 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 8589.5
If we subtract 420 from 430, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
When dividing 100 by 84, we get 1 with a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 8589.51
If we take 84 away from 100, 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.

Moving on to step 9:
84 can be fit into 160 1 times, resulting in a remainder of 76.
The next digit of our result is 1. 
Result so far: 8589.511
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.

The quotient of the division is 8589.511, and the remainder is 0.0076.
