We're dividing 728566 by 78 
We want to figure out the number of times 728566 can be divided by 78.

On to step 1:
78 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 78

Advancing to step 2:
78 can be fit into 72 0 times, resulting in a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 72 after subtracting 0 from 72.
Grab the next digit (8) from the dividend, add it to 72, then carry on: 728 / 78

Going ahead to step 3:
If we divide 728 by 78, we get 9 and a remainder of 26.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Deduct 702 from 728 and we're left with 26.
Bring next digit (5) of the dividend behind the 26 and repeat the process: 265 / 78

Step 4:
78 goes into 265 3 times with a remainder of 31.
Use 3 as the next digit of our solution. 
Result so far: 93.0
Subtract 234 from 265 to get 31.
Grab the next digit (6) from the dividend, add it to 31, then carry on: 316 / 78

Advancing to step 5:
78 goes into 316 4 times with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 934.0
The remainder is 4 after subtracting 312 from 316.
Grab the next digit (6) from the dividend, add it to 4, then carry on: 46 / 78

Moving on to step 6:
When dividing 46 by 78, we get 0 with a remainder of 46.
The number 0 becomes the next digit in our result. 
Result so far: 9340.0
Subtract 0 from 46 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 7:
The number 78 fits into 460 5 times, leaving a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 9340.5
If we take 390 away from 460, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 8:
The number 78 fits into 700 8 times, leaving a remainder of 76.
The number 8 becomes the next digit in our result. 
Result so far: 9340.58
Subtract 624 from 700 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 9:
The number 78 fits into 760 9 times, leaving a remainder of 58.
Record the quotient 9 as the next digit in the result. 
Result so far: 9340.589
If we take 702 away from 760, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 10:
580 divided by 78 is 7 with a remainder of 34.
Write down 7 as next digit of the result. 
Result so far: 9340.5897
If we take 546 away from 580, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 11:
When dividing 340 by 78, we get 4 with a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 9340.58974
Subtracting 312 from 340 leaves us 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.

Moving on to step 12:
If we divide 280 by 78, we get 3 and a remainder of 46.
The number 3 becomes the next digit in our result. 
Result so far: 9340.589743
If we take 234 away from 280, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 13:
78 can be fit into 460 5 times, resulting in a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 9340.5897435
If we take 390 away from 460, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 14:
78 can be fit into 700 8 times, resulting in a remainder of 76.
Put 8 as the next digit of the answer. 
Result so far: 9340.58974358
If we take 624 away from 700, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

The final result is 9340.58974358 with a remainder of 7.6e-08.
