64673119 divided by 728 
We want to figure out the number of times 64673119 can be divided by 728.

Let's proceed to step 1:
6 divided by 728 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 728

Moving on to step 2:
728 goes into 64 0 times with a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Take the next digit (6) from the dividend and append it to 64, then repeat: 646 / 728

On to step 3:
The number 728 fits into 646 0 times, leaving a remainder of 646.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 646 and we're left with 646.
Append the next digit (7) from the dividend to 646 and continue with: 6467 / 728

Moving on to step 4:
6467 divided by 728 is 8 with a remainder of 643.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 5824 from 6467 leaves us with 643.
Append the next digit (3) from the dividend to 643 and continue with: 6433 / 728

Let's proceed to step 5:
If we divide 6433 by 728, we get 8 and a remainder of 609.
The next digit of our result is 8. 
Result so far: 88.0
Deduct 5824 from 6433 and we're left with 609.
Take the next digit (1) from the dividend and append it to 609, then repeat: 6091 / 728

Step 6:
6091 divided by 728 is 8 with a remainder of 267.
Record the quotient 8 as the next digit in the result. 
Result so far: 888.0
If we subtract 5824 from 6091, we get 267.
Bring next digit (1) of the dividend behind the 267 and repeat the process: 2671 / 728

On to step 7:
When dividing 2671 by 728, we get 3 with a remainder of 487.
Write down 3 as next digit of the result. 
Result so far: 8883.0
If we subtract 2184 from 2671, we get 487.
Grab the next digit (9) from the dividend, add it to 487, then carry on: 4879 / 728

On to step 8:
4879 divided by 728 is 6 with a remainder of 511.
The number 6 becomes the next digit in our result. 
Result so far: 88836.0
Deduct 4368 from 4879 and we're left with 511.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5110, and continue the process.

Moving on to step 9:
When dividing 5110 by 728, we get 7 with a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 88836.7
If we subtract 5096 from 5110, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 10:
728 goes into 140 0 times with a remainder of 140.
The next digit of our result is 0. 
Result so far: 88836.7
If we take 0 away from 140, we end up 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.

Step 11:
If we divide 1400 by 728, we get 1 and a remainder of 672.
The next digit of our result is 1. 
Result so far: 88836.701
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.

Let's proceed to step 12:
728 can be fit into 6720 9 times, resulting in a remainder of 168.
Put 9 as the next digit of the answer. 
Result so far: 88836.7019
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.

On to step 13:
If we divide 1680 by 728, we get 2 and a remainder of 224.
Write down 2 as next digit of the result. 
Result so far: 88836.70192
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 14:
728 goes into 2240 3 times with a remainder of 56.
The number 3 becomes the next digit in our result. 
Result so far: 88836.701923
If we subtract 2184 from 2240, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 15:
560 divided by 728 is 0 with a remainder of 560.
Record the quotient 0 as the next digit in the result. 
Result so far: 88836.701923
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.

On to step 16:
5600 divided by 728 is 7 with a remainder of 504.
Use 7 as the next digit of our solution. 
Result so far: 88836.70192307
If we take 5096 away from 5600, we end up 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.

In conclusion, the division gives 88836.70192307 with a balance of 5.04e-07.
