We look at the division of 515308 by 78 
We want to divide 515308 by 78.

Step 1:
78 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 78

Advancing to step 2:
51 divided by 78 is 0 with a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Take the next digit (5) from the dividend and append it to 51, then repeat: 515 / 78

Moving on to step 3:
When dividing 515 by 78, we get 6 with a remainder of 47.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 47 after subtracting 468 from 515.
Append the next digit (3) from the dividend to 47 and continue with: 473 / 78

Advancing to step 4:
If we divide 473 by 78, we get 6 and a remainder of 5.
Record the quotient 6 as the next digit in the result. 
Result so far: 66.0
Subtracting 468 from 473 leaves us with 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 78

On to step 5:
50 divided by 78 is 0 with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 660.0
If we take 0 away from 50, we end up with 50.
Fetch the next digit (8) from the dividend, attach it to 50 and continue: 508 / 78

On to step 6:
78 can be fit into 508 6 times, resulting in a remainder of 40.
Record the quotient 6 as the next digit in the result. 
Result so far: 6606.0
Subtract 468 from 508 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.

Advancing to step 7:
78 goes into 400 5 times with a remainder of 10.
The next digit of our result is 5. 
Result so far: 6606.5
The remainder is 10 after subtracting 390 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
100 divided by 78 is 1 with a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 6606.51
Subtract 78 from 100 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 9:
220 divided by 78 is 2 with a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 6606.512
The remainder is 64 after subtracting 156 from 220.
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 10:
When dividing 640 by 78, we get 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 6606.5128
The remainder is 16 after subtracting 624 from 640.
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 11:
If we divide 160 by 78, we get 2 and a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 6606.51282
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.

Going ahead to step 12:
40 divided by 78 is 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 6606.51282
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 13:
78 goes into 400 5 times with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 6606.5128205
Subtract 390 from 400 to 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.

Advancing to step 14:
If we divide 100 by 78, we get 1 and a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 6606.51282051
Subtract 78 from 100 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final outcome is 6606.51282051, with a leftover of 2.2e-08.
