We're dividing 27715 by 78 
We want to figure out the number of times 27715 can be divided by 78.

Step 1:
2 divided by 78 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 78

On to step 2:
The number 78 fits into 27 0 times, leaving a remainder of 27.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 27, we get 27.
Bring next digit (7) of the dividend behind the 27 and repeat the process: 277 / 78

On to step 3:
78 can be fit into 277 3 times, resulting in a remainder of 43.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 234 from 277 leaves us with 43.
Append the next digit (1) from the dividend to 43 and continue with: 431 / 78

Going ahead to step 4:
The number 78 fits into 431 5 times, leaving a remainder of 41.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
Subtract 390 from 431 to get 41.
Grab the next digit (5) from the dividend, add it to 41, then carry on: 415 / 78

Step 5:
The number 78 fits into 415 5 times, leaving a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 355.0
Subtracting 390 from 415 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 6:
78 can be fit into 250 3 times, resulting in a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 355.3
Subtracting 234 from 250 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 7:
The number 78 fits into 160 2 times, leaving a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 355.32
Deduct 156 from 160 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 8:
78 goes into 40 0 times with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 355.32
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
78 can be fit into 400 5 times, resulting in a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 355.3205
If we subtract 390 from 400, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
If we divide 100 by 78, we get 1 and a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 355.32051
Deduct 78 from 100 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 11:
The number 78 fits into 220 2 times, leaving a remainder of 64.
Put 2 as the next digit of the answer. 
Result so far: 355.320512
Deduct 156 from 220 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 12:
640 divided by 78 is 8 with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 355.3205128
If we subtract 624 from 640, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 13:
78 goes into 160 2 times with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 355.32051282
Deduct 156 from 160 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

After the division, we end up with 355.32051282 and a remainder of 4e-09.
