78679990 ÷ 728 
We want to divide 78679990 by 728.

Moving on to step 1:
728 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 728

Advancing to step 2:
If we divide 78 by 728, we get 0 and a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Bring next digit (6) of the dividend behind the 78 and repeat the process: 786 / 728

On to step 3:
The number 728 fits into 786 1 times, leaving a remainder of 58.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 728 from 786 and we're left with 58.
Grab the next digit (7) from the dividend, add it to 58, then carry on: 587 / 728

Going ahead to step 4:
When dividing 587 by 728, we get 0 with a remainder of 587.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtracting 0 from 587 leaves us with 587.
Fetch the next digit (9) from the dividend, attach it to 587 and continue: 5879 / 728

Going ahead to step 5:
5879 divided by 728 is 8 with a remainder of 55.
Put 8 as the next digit of the answer. 
Result so far: 108.0
Deduct 5824 from 5879 and we're left with 55.
Append the next digit (9) from the dividend to 55 and continue with: 559 / 728

Advancing to step 6:
728 goes into 559 0 times with a remainder of 559.
Write down 0 as next digit of the result. 
Result so far: 1080.0
The remainder is 559 after subtracting 0 from 559.
Fetch the next digit (9) from the dividend, attach it to 559 and continue: 5599 / 728

Advancing to step 7:
728 can be fit into 5599 7 times, resulting in a remainder of 503.
The number 7 becomes the next digit in our result. 
Result so far: 10807.0
Subtract 5096 from 5599 to get 503.
Grab the next digit (0) from the dividend, add it to 503, then carry on: 5030 / 728

Going ahead to step 8:
728 can be fit into 5030 6 times, resulting in a remainder of 662.
Put 6 as the next digit of the answer. 
Result so far: 108076.0
Deduct 4368 from 5030 and we're left with 662.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6620, and continue the process.

Let's proceed to step 9:
6620 divided by 728 is 9 with a remainder of 68.
Record the quotient 9 as the next digit in the result. 
Result so far: 108076.9
If we take 6552 away from 6620, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 10:
680 divided by 728 is 0 with a remainder of 680.
The next digit of our result is 0. 
Result so far: 108076.9
Subtract 0 from 680 to get 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Step 11:
If we divide 6800 by 728, we get 9 and a remainder of 248.
The number 9 becomes the next digit in our result. 
Result so far: 108076.909
If we take 6552 away from 6800, we end up with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

On to step 12:
If we divide 2480 by 728, we get 3 and a remainder of 296.
The next digit of our result is 3. 
Result so far: 108076.9093
If we take 2184 away from 2480, we end up with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

On to step 13:
728 can be fit into 2960 4 times, resulting in a remainder of 48.
Use 4 as the next digit of our solution. 
Result so far: 108076.90934
The remainder is 48 after subtracting 2912 from 2960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 14:
728 can be fit into 480 0 times, resulting in a remainder of 480.
The next digit of our result is 0. 
Result so far: 108076.90934
If we take 0 away from 480, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Moving on to step 15:
The number 728 fits into 4800 6 times, leaving a remainder of 432.
Use 6 as the next digit of our solution. 
Result so far: 108076.9093406
Deduct 4368 from 4800 and we're left with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Step 16:
The number 728 fits into 4320 5 times, leaving a remainder of 680.
Put 5 as the next digit of the answer. 
Result so far: 108076.90934065
Subtract 3640 from 4320 to get 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

After the division, we end up with 108076.90934065 and a remainder of 6.8e-07.
