We look at the division of 72055754 by 721 
We want to divide 72055754 by 721.

Advancing to step 1:
If we divide 7 by 721, we get 0 and 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.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 721

Going ahead to step 2:
The number 721 fits into 72 0 times, leaving a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 72, we end up with 72.
Bring next digit (0) of the dividend behind the 72 and repeat the process: 720 / 721

Let's proceed to step 3:
721 goes into 720 0 times with a remainder of 720.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 720, we get 720.
Bring next digit (5) of the dividend behind the 720 and repeat the process: 7205 / 721

Moving on to step 4:
7205 divided by 721 is 9 with a remainder of 716.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtracting 6489 from 7205 leaves us with 716.
Bring next digit (5) of the dividend behind the 716 and repeat the process: 7165 / 721

Let's proceed to step 5:
721 can be fit into 7165 9 times, resulting in a remainder of 676.
Put 9 as the next digit of the answer. 
Result so far: 99.0
Subtracting 6489 from 7165 leaves us with 676.
Include the next digit (7) from the dividend after 676, then repeat: 6767 / 721

Going ahead to step 6:
721 can be fit into 6767 9 times, resulting in a remainder of 278.
Use 9 as the next digit of our solution. 
Result so far: 999.0
Subtract 6489 from 6767 to get 278.
Take the next digit (5) from the dividend and append it to 278, then repeat: 2785 / 721

Going ahead to step 7:
The number 721 fits into 2785 3 times, leaving a remainder of 622.
The next digit of our result is 3. 
Result so far: 9993.0
Subtracting 2163 from 2785 leaves us with 622.
Include the next digit (4) from the dividend after 622, then repeat: 6224 / 721

Advancing to step 8:
721 can be fit into 6224 8 times, resulting in a remainder of 456.
Write down 8 as next digit of the result. 
Result so far: 99938.0
Subtract 5768 from 6224 to get 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Step 9:
4560 divided by 721 is 6 with a remainder of 234.
The number 6 becomes the next digit in our result. 
Result so far: 99938.6
If we take 4326 away from 4560, we end up with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Step 10:
If we divide 2340 by 721, we get 3 and a remainder of 177.
The next digit of our result is 3. 
Result so far: 99938.63
If we take 2163 away from 2340, we end up with 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

On to step 11:
721 can be fit into 1770 2 times, resulting in a remainder of 328.
Use 2 as the next digit of our solution. 
Result so far: 99938.632
The remainder is 328 after subtracting 1442 from 1770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Advancing to step 12:
3280 divided by 721 is 4 with a remainder of 396.
Record the quotient 4 as the next digit in the result. 
Result so far: 99938.6324
Subtracting 2884 from 3280 leaves us with 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Step 13:
721 can be fit into 3960 5 times, resulting in a remainder of 355.
Put 5 as the next digit of the answer. 
Result so far: 99938.63245
If we subtract 3605 from 3960, we get 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Advancing to step 14:
The number 721 fits into 3550 4 times, leaving a remainder of 666.
Put 4 as the next digit of the answer. 
Result so far: 99938.632454
Subtracting 2884 from 3550 leaves us with 666.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6660, and continue the process.

Step 15:
6660 divided by 721 is 9 with a remainder of 171.
Record the quotient 9 as the next digit in the result. 
Result so far: 99938.6324549
Subtract 6489 from 6660 to get 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Step 16:
721 can be fit into 1710 2 times, resulting in a remainder of 268.
The number 2 becomes the next digit in our result. 
Result so far: 99938.63245492
Deduct 1442 from 1710 and we're left with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

The final result is 99938.63245492 with a remainder of 2.68e-07.
