We look at the division of 19721443 by 728 
We're looking to find how many times 728 goes into 19721443.

Going ahead to step 1:
1 divided by 728 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 728

Advancing to step 2:
728 can be fit into 19 0 times, resulting in a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 19, we end up with 19.
Take the next digit (7) from the dividend and append it to 19, then repeat: 197 / 728

Advancing to step 3:
The number 728 fits into 197 0 times, leaving a remainder of 197.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 197 after subtracting 0 from 197.
Bring next digit (2) of the dividend behind the 197 and repeat the process: 1972 / 728

Step 4:
When dividing 1972 by 728, we get 2 with a remainder of 516.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 1456 from 1972, we get 516.
Take the next digit (1) from the dividend and append it to 516, then repeat: 5161 / 728

Let's proceed to step 5:
728 goes into 5161 7 times with a remainder of 65.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
If we take 5096 away from 5161, we end up with 65.
Include the next digit (4) from the dividend after 65, then repeat: 654 / 728

On to step 6:
728 goes into 654 0 times with a remainder of 654.
Use 0 as the next digit of our solution. 
Result so far: 270.0
Subtract 0 from 654 to get 654.
Append the next digit (4) from the dividend to 654 and continue with: 6544 / 728

Step 7:
6544 divided by 728 is 8 with a remainder of 720.
Put 8 as the next digit of the answer. 
Result so far: 2708.0
If we take 5824 away from 6544, we end up with 720.
Fetch the next digit (3) from the dividend, attach it to 720 and continue: 7203 / 728

Moving on to step 8:
728 can be fit into 7203 9 times, resulting in a remainder of 651.
The number 9 becomes the next digit in our result. 
Result so far: 27089.0
If we take 6552 away from 7203, we end up with 651.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6510, and continue the process.

Moving on to step 9:
728 can be fit into 6510 8 times, resulting in a remainder of 686.
The number 8 becomes the next digit in our result. 
Result so far: 27089.8
The remainder is 686 after subtracting 5824 from 6510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6860, and continue the process.

Moving on to step 10:
The number 728 fits into 6860 9 times, leaving a remainder of 308.
Use 9 as the next digit of our solution. 
Result so far: 27089.89
The remainder is 308 after subtracting 6552 from 6860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Advancing to step 11:
If we divide 3080 by 728, we get 4 and a remainder of 168.
Record the quotient 4 as the next digit in the result. 
Result so far: 27089.894
If we subtract 2912 from 3080, we get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Let's proceed to step 12:
The number 728 fits into 1680 2 times, leaving a remainder of 224.
Use 2 as the next digit of our solution. 
Result so far: 27089.8942
If we subtract 1456 from 1680, we get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Moving on to step 13:
728 goes into 2240 3 times with a remainder of 56.
The number 3 becomes the next digit in our result. 
Result so far: 27089.89423
If we take 2184 away from 2240, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 14:
728 goes into 560 0 times with a remainder of 560.
Record the quotient 0 as the next digit in the result. 
Result so far: 27089.89423
Subtract 0 from 560 to get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Advancing to step 15:
If we divide 5600 by 728, we get 7 and a remainder of 504.
Use 7 as the next digit of our solution. 
Result so far: 27089.8942307
Deduct 5096 from 5600 and we're left with 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Step 16:
If we divide 5040 by 728, we get 6 and a remainder of 672.
Put 6 as the next digit of the answer. 
Result so far: 27089.89423076
The remainder is 672 after subtracting 4368 from 5040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

The final result is 27089.89423076 with a remainder of 6.72e-07.
