We're dividing 77739495 by 728 
Let's see how many times 728 fits into 77739495.

On to step 1:
When dividing 7 by 728, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 728

Moving on to step 2:
When dividing 77 by 728, we get 0 with a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 77, we end up with 77.
Bring next digit (7) of the dividend behind the 77 and repeat the process: 777 / 728

On to step 3:
The number 728 fits into 777 1 times, leaving a remainder of 49.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 49 after subtracting 728 from 777.
Grab the next digit (3) from the dividend, add it to 49, then carry on: 493 / 728

On to step 4:
493 divided by 728 is 0 with a remainder of 493.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we subtract 0 from 493, we get 493.
Bring next digit (9) of the dividend behind the 493 and repeat the process: 4939 / 728

Going ahead to step 5:
728 can be fit into 4939 6 times, resulting in a remainder of 571.
The number 6 becomes the next digit in our result. 
Result so far: 106.0
Subtract 4368 from 4939 to get 571.
Take the next digit (4) from the dividend and append it to 571, then repeat: 5714 / 728

Going ahead to step 6:
The number 728 fits into 5714 7 times, leaving a remainder of 618.
Use 7 as the next digit of our solution. 
Result so far: 1067.0
The remainder is 618 after subtracting 5096 from 5714.
Append the next digit (9) from the dividend to 618 and continue with: 6189 / 728

Step 7:
If we divide 6189 by 728, we get 8 and a remainder of 365.
Put 8 as the next digit of the answer. 
Result so far: 10678.0
Subtracting 5824 from 6189 leaves us with 365.
Grab the next digit (5) from the dividend, add it to 365, then carry on: 3655 / 728

Advancing to step 8:
3655 divided by 728 is 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 106785.0
The remainder is 15 after subtracting 3640 from 3655.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 9:
728 can be fit into 150 0 times, resulting in a remainder of 150.
Put 0 as the next digit of the answer. 
Result so far: 106785.0
Subtract 0 from 150 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 10:
If we divide 1500 by 728, we get 2 and a remainder of 44.
Use 2 as the next digit of our solution. 
Result so far: 106785.02
The remainder is 44 after subtracting 1456 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 11:
When dividing 440 by 728, we get 0 with a remainder of 440.
The next digit of our result is 0. 
Result so far: 106785.02
If we subtract 0 from 440, we get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Advancing to step 12:
If we divide 4400 by 728, we get 6 and a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 106785.0206
If we take 4368 away from 4400, we end up with 32.
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 13:
If we divide 320 by 728, we get 0 and a remainder of 320.
Write down 0 as next digit of the result. 
Result so far: 106785.0206
Deduct 0 from 320 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 14:
The number 728 fits into 3200 4 times, leaving a remainder of 288.
Write down 4 as next digit of the result. 
Result so far: 106785.020604
If we take 2912 away from 3200, we end up with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Moving on to step 15:
728 can be fit into 2880 3 times, resulting in a remainder of 696.
Use 3 as the next digit of our solution. 
Result so far: 106785.0206043
The remainder is 696 after subtracting 2184 from 2880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6960, and continue the process.

On to step 16:
728 can be fit into 6960 9 times, resulting in a remainder of 408.
Use 9 as the next digit of our solution. 
Result so far: 106785.02060439
Subtracting 6552 from 6960 leaves us with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

After the division, we end up with 106785.02060439 and a remainder of 4.08e-07.
