728143 divided by 64 
We want to figure out the number of times 728143 can be divided by 64.

Going ahead to step 1:
If we divide 7 by 64, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 64

Advancing to step 2:
64 goes into 72 1 times with a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 64 away from 72, we end up with 8.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 64

Moving on to step 3:
64 can be fit into 88 1 times, resulting in a remainder of 24.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Deduct 64 from 88 and we're left with 24.
Append the next digit (1) from the dividend to 24 and continue with: 241 / 64

On to step 4:
241 divided by 64 is 3 with a remainder of 49.
Put 3 as the next digit of the answer. 
Result so far: 113.0
Subtracting 192 from 241 leaves us with 49.
Bring next digit (4) of the dividend behind the 49 and repeat the process: 494 / 64

Step 5:
If we divide 494 by 64, we get 7 and a remainder of 46.
Record the quotient 7 as the next digit in the result. 
Result so far: 1137.0
Subtracting 448 from 494 leaves us with 46.
Grab the next digit (3) from the dividend, add it to 46, then carry on: 463 / 64

On to step 6:
If we divide 463 by 64, we get 7 and a remainder of 15.
Use 7 as the next digit of our solution. 
Result so far: 11377.0
Subtract 448 from 463 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 7:
150 divided by 64 is 2 with a remainder of 22.
Use 2 as the next digit of our solution. 
Result so far: 11377.2
If we subtract 128 from 150, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 8:
64 can be fit into 220 3 times, resulting in a remainder of 28.
Use 3 as the next digit of our solution. 
Result so far: 11377.23
Deduct 192 from 220 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 9:
The number 64 fits into 280 4 times, leaving a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 11377.234
Subtracting 256 from 280 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 10:
If we divide 240 by 64, we get 3 and a remainder of 48.
Use 3 as the next digit of our solution. 
Result so far: 11377.2343
Subtracting 192 from 240 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 11:
The number 64 fits into 480 7 times, leaving a remainder of 32.
Put 7 as the next digit of the answer. 
Result so far: 11377.23437
The remainder is 32 after subtracting 448 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 12:
320 divided by 64 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 11377.234375
If we take 320 away from 320, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 13:
0 divided by 64 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 11377.234375
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 14:
When dividing 0 by 64, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 11377.234375
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 11377.234375 and a remainder of 0.0.
