73660001 ÷ 728 
We want to figure out the number of times 73660001 can be divided by 728.

Step 1:
728 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 728

Going ahead to step 2:
If we divide 73 by 728, we get 0 and a remainder of 73.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 73 and we're left with 73.
Fetch the next digit (6) from the dividend, attach it to 73 and continue: 736 / 728

Step 3:
728 can be fit into 736 1 times, resulting in a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 728 from 736 and we're left with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 728

On to step 4:
When dividing 86 by 728, we get 0 with a remainder of 86.
The next digit of our result is 0. 
Result so far: 10.0
Subtracting 0 from 86 leaves us with 86.
Bring next digit (0) of the dividend behind the 86 and repeat the process: 860 / 728

Advancing to step 5:
728 can be fit into 860 1 times, resulting in a remainder of 132.
Put 1 as the next digit of the answer. 
Result so far: 101.0
Subtract 728 from 860 to get 132.
Fetch the next digit (0) from the dividend, attach it to 132 and continue: 1320 / 728

Let's proceed to step 6:
If we divide 1320 by 728, we get 1 and a remainder of 592.
Record the quotient 1 as the next digit in the result. 
Result so far: 1011.0
If we subtract 728 from 1320, we get 592.
Bring next digit (0) of the dividend behind the 592 and repeat the process: 5920 / 728

Step 7:
728 goes into 5920 8 times with a remainder of 96.
Write down 8 as next digit of the result. 
Result so far: 10118.0
If we subtract 5824 from 5920, we get 96.
Take the next digit (1) from the dividend and append it to 96, then repeat: 961 / 728

Let's proceed to step 8:
728 can be fit into 961 1 times, resulting in a remainder of 233.
Write down 1 as next digit of the result. 
Result so far: 101181.0
If we subtract 728 from 961, we get 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Going ahead to step 9:
The number 728 fits into 2330 3 times, leaving a remainder of 146.
Record the quotient 3 as the next digit in the result. 
Result so far: 101181.3
The remainder is 146 after subtracting 2184 from 2330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Let's proceed to step 10:
728 goes into 1460 2 times with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 101181.32
Subtract 1456 from 1460 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 11:
The number 728 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 101181.32
Subtracting 0 from 40 leaves us 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.

Moving on to step 12:
728 can be fit into 400 0 times, resulting in a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 101181.32
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

After the division, we end up with 101181.32 and a remainder of 0.004.
