We look at the division of 66636164 by 728 
We want to divide 66636164 by 728.

Advancing to step 1:
The number 728 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 728

Advancing to step 2:
If we divide 66 by 728, we get 0 and a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Include the next digit (6) from the dividend after 66, then repeat: 666 / 728

On to step 3:
When dividing 666 by 728, we get 0 with a remainder of 666.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 666 leaves us with 666.
Fetch the next digit (3) from the dividend, attach it to 666 and continue: 6663 / 728

Let's proceed to step 4:
728 can be fit into 6663 9 times, resulting in a remainder of 111.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Deduct 6552 from 6663 and we're left with 111.
Grab the next digit (6) from the dividend, add it to 111, then carry on: 1116 / 728

Advancing to step 5:
If we divide 1116 by 728, we get 1 and a remainder of 388.
Put 1 as the next digit of the answer. 
Result so far: 91.0
Subtract 728 from 1116 to get 388.
Fetch the next digit (1) from the dividend, attach it to 388 and continue: 3881 / 728

On to step 6:
When dividing 3881 by 728, we get 5 with a remainder of 241.
Write down 5 as next digit of the result. 
Result so far: 915.0
Subtract 3640 from 3881 to get 241.
Bring next digit (6) of the dividend behind the 241 and repeat the process: 2416 / 728

Advancing to step 7:
728 can be fit into 2416 3 times, resulting in a remainder of 232.
Use 3 as the next digit of our solution. 
Result so far: 9153.0
The remainder is 232 after subtracting 2184 from 2416.
Fetch the next digit (4) from the dividend, attach it to 232 and continue: 2324 / 728

Let's proceed to step 8:
The number 728 fits into 2324 3 times, leaving a remainder of 140.
Put 3 as the next digit of the answer. 
Result so far: 91533.0
Deduct 2184 from 2324 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 9:
1400 divided by 728 is 1 with a remainder of 672.
The next digit of our result is 1. 
Result so far: 91533.1
Deduct 728 from 1400 and we're left with 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

On to step 10:
If we divide 6720 by 728, we get 9 and a remainder of 168.
Put 9 as the next digit of the answer. 
Result so far: 91533.19
Deduct 6552 from 6720 and we're left with 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 11:
The number 728 fits into 1680 2 times, leaving a remainder of 224.
Record the quotient 2 as the next digit in the result. 
Result so far: 91533.192
If we take 1456 away from 1680, we end up with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

On to step 12:
728 can be fit into 2240 3 times, resulting in a remainder of 56.
Write down 3 as next digit of the result. 
Result so far: 91533.1923
Deduct 2184 from 2240 and we're left 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.

Moving on to step 13:
728 can be fit into 560 0 times, resulting in a remainder of 560.
Record the quotient 0 as the next digit in the result. 
Result so far: 91533.1923
If we subtract 0 from 560, we 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.

Going ahead to step 14:
The number 728 fits into 5600 7 times, leaving a remainder of 504.
Use 7 as the next digit of our solution. 
Result so far: 91533.192307
Subtracting 5096 from 5600 leaves us 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.

On to step 15:
728 can be fit into 5040 6 times, resulting in a remainder of 672.
Use 6 as the next digit of our solution. 
Result so far: 91533.1923076
Deduct 4368 from 5040 and we're left with 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

Going ahead to step 16:
When dividing 6720 by 728, we get 9 with a remainder of 168.
Use 9 as the next digit of our solution. 
Result so far: 91533.19230769
Subtracting 6552 from 6720 leaves us with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

The final result is 91533.19230769 with a remainder of 1.68e-07.
