We're dividing 7879115 by 279 
We're looking to find how many times 279 goes into 7879115.

Let's proceed to step 1:
If we divide 7 by 279, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 279

Advancing to step 2:
The number 279 fits into 78 0 times, leaving a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Include the next digit (7) from the dividend after 78, then repeat: 787 / 279

Let's proceed to step 3:
279 goes into 787 2 times with a remainder of 229.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 558 from 787 to get 229.
Grab the next digit (9) from the dividend, add it to 229, then carry on: 2299 / 279

On to step 4:
279 goes into 2299 8 times with a remainder of 67.
Use 8 as the next digit of our solution. 
Result so far: 28.0
Deduct 2232 from 2299 and we're left with 67.
Grab the next digit (1) from the dividend, add it to 67, then carry on: 671 / 279

Going ahead to step 5:
When dividing 671 by 279, we get 2 with a remainder of 113.
Put 2 as the next digit of the answer. 
Result so far: 282.0
Subtracting 558 from 671 leaves us with 113.
Append the next digit (1) from the dividend to 113 and continue with: 1131 / 279

On to step 6:
1131 divided by 279 is 4 with a remainder of 15.
The next digit of our result is 4. 
Result so far: 2824.0
Subtract 1116 from 1131 to get 15.
Include the next digit (5) from the dividend after 15, then repeat: 155 / 279

On to step 7:
279 goes into 155 0 times with a remainder of 155.
Use 0 as the next digit of our solution. 
Result so far: 28240.0
Subtract 0 from 155 to get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Step 8:
279 goes into 1550 5 times with a remainder of 155.
Put 5 as the next digit of the answer. 
Result so far: 28240.5
If we subtract 1395 from 1550, we get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Step 9:
When dividing 1550 by 279, we get 5 with a remainder of 155.
Record the quotient 5 as the next digit in the result. 
Result so far: 28240.55
The remainder is 155 after subtracting 1395 from 1550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Our division results in 28240.55 with a remaining 0.155.
