Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 721

Step 2:
47 divided by 721 is 0 with a remainder of 47.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 47 and we're left with 47.
Include the next digit (3) from the dividend after 47, then repeat: 473 / 721

Let's proceed to step 3:
The number 721 fits into 473 0 times, leaving a remainder of 473.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 473 and we're left with 473.

721 can be fit into 4732 6 times, resulting in a remainder of 406.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 4326 from 4732 to get 406.
Grab the next digit (5) from the dividend, add it to 406, then carry on: 4065 / 721

On to step 5:
When dividing 4065 by 721, we get 5 with a remainder of 460.
The next digit of our result is 5. 
Result so far: 65.0
Subtracting 3605 from 4065 leaves us with 460.
Append the next digit (6) from the dividend to 460 and continue with: 4606 / 721

Step 6:
721 can be fit into 4606 6 times, resulting in a remainder of 280.
The number 6 becomes the next digit in our result. 
Result so far: 656.0
If we take 4326 away from 4606, we end up with 280.
Grab the next digit (9) from the dividend, add it to 280, then carry on: 2809 / 721

Moving on to step 7:
The number 721 fits into 2809 3 times, leaving a remainder of 646.
The next digit of our result is 3. 
Result so far: 6563.0
The remainder is 646 after subtracting 2163 from 2809.
Grab the next digit (7) from the dividend, add it to 646, then carry on: 6467 / 721

On to step 8:
721 can be fit into 6467 8 times, resulting in a remainder of 699.
Put 8 as the next digit of the answer. 
Result so far: 65638.0
Subtracting 5768 from 6467 leaves us with 699.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6990, and continue the process.

On to step 9:
When dividing 6990 by 721, we get 9 with a remainder of 501.
Put 9 as the next digit of the answer. 
Result so far: 65638.9
The remainder is 501 after subtracting 6489 from 6990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5010, and continue the process.

Moving on to step 10:
The number 721 fits into 5010 6 times, leaving a remainder of 684.
Record the quotient 6 as the next digit in the result. 
Result so far: 65638.96
Subtracting 4326 from 5010 leaves us with 684.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6840, and continue the process.

Advancing to step 11:
6840 divided by 721 is 9 with a remainder of 351.
Write down 9 as next digit of the result. 
Result so far: 65638.969
Deduct 6489 from 6840 and we're left with 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Advancing to step 12:
721 goes into 3510 4 times with a remainder of 626.
Put 4 as the next digit of the answer. 
Result so far: 65638.9694
Deduct 2884 from 3510 and we're left with 626.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6260, and continue the process.

Advancing to step 13:
When dividing 6260 by 721, we get 8 with a remainder of 492.
Record the quotient 8 as the next digit in the result. 
Result so far: 65638.96948
If we take 5768 away from 6260, we end up with 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

Step 14:
When dividing 4920 by 721, we get 6 with a remainder of 594.
Record the quotient 6 as the next digit in the result. 
Result so far: 65638.969486
If we take 4326 away from 4920, we end up with 594.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5940, and continue the process.

Let's proceed to step 15:
If we divide 5940 by 721, we get 8 and a remainder of 172.
The number 8 becomes the next digit in our result. 
Result so far: 65638.9694868
Subtract 5768 from 5940 to get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Advancing to step 16:
The number 721 fits into 1720 2 times, leaving a remainder of 278.
Write down 2 as next digit of the result. 
Result so far: 65638.96948682
Subtracting 1442 from 1720 leaves us with 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

The final outcome is 65638.96948682, with a leftover of 2.78e-07.
