879030 divided by 78 
We're looking to find how many times 78 goes into 879030.

Step 1:
When dividing 8 by 78, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 78

Going ahead to step 2:
When dividing 87 by 78, we get 1 with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 78 from 87 to get 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 78

Moving on to step 3:
The number 78 fits into 99 1 times, leaving a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we take 78 away from 99, we end up with 21.
Append the next digit (0) from the dividend to 21 and continue with: 210 / 78

Moving on to step 4:
When dividing 210 by 78, we get 2 with a remainder of 54.
Record the quotient 2 as the next digit in the result. 
Result so far: 112.0
If we subtract 156 from 210, we get 54.
Append the next digit (3) from the dividend to 54 and continue with: 543 / 78

On to step 5:
543 divided by 78 is 6 with a remainder of 75.
The next digit of our result is 6. 
Result so far: 1126.0
Subtract 468 from 543 to get 75.
Take the next digit (0) from the dividend and append it to 75, then repeat: 750 / 78

Going ahead to step 6:
The number 78 fits into 750 9 times, leaving a remainder of 48.
Put 9 as the next digit of the answer. 
Result so far: 11269.0
Subtract 702 from 750 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 7:
The number 78 fits into 480 6 times, leaving a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 11269.6
Deduct 468 from 480 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 8:
78 goes into 120 1 times with a remainder of 42.
Put 1 as the next digit of the answer. 
Result so far: 11269.61
Subtracting 78 from 120 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 9:
When dividing 420 by 78, we get 5 with a remainder of 30.
The next digit of our result is 5. 
Result so far: 11269.615
The remainder is 30 after subtracting 390 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 10:
300 divided by 78 is 3 with a remainder of 66.
Use 3 as the next digit of our solution. 
Result so far: 11269.6153
If we subtract 234 from 300, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 11:
78 can be fit into 660 8 times, resulting in a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 11269.61538
Subtracting 624 from 660 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 12:
If we divide 360 by 78, we get 4 and a remainder of 48.
The next digit of our result is 4. 
Result so far: 11269.615384
The remainder is 48 after subtracting 312 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 13:
78 goes into 480 6 times with a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 11269.6153846
Subtract 468 from 480 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 14:
78 goes into 120 1 times with a remainder of 42.
The next digit of our result is 1. 
Result so far: 11269.61538461
Subtracting 78 from 120 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

After the division, we end up with 11269.61538461 and a remainder of 4.2e-08.
