Let's divide 515669 by 78
We're looking to find how many times 78 goes into 515669.

Step 1:
78 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 78

Advancing to step 2:
If we divide 51 by 78, we get 0 and a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Bring next digit (5) of the dividend behind the 51 and repeat the process: 515 / 78

Moving on to step 3:
The number 78 fits into 515 6 times, leaving a remainder of 47.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtracting 468 from 515 leaves us with 47.
Grab the next digit (6) from the dividend, add it to 47, then carry on: 476 / 78

Let's proceed to step 4:
If we divide 476 by 78, we get 6 and a remainder of 8.
The next digit of our result is 6. 
Result so far: 66.0
If we subtract 468 from 476, we get 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 78

Let's proceed to step 5:
The number 78 fits into 86 1 times, leaving a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 661.0
Subtract 78 from 86 to get 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 78

Going ahead to step 6:
89 divided by 78 is 1 with a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 6611.0
If we take 78 away from 89, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 7:
78 goes into 110 1 times with a remainder of 32.
Record the quotient 1 as the next digit in the result. 
Result so far: 6611.1
Subtracting 78 from 110 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 8:
78 can be fit into 320 4 times, resulting in a remainder of 8.
The next digit of our result is 4. 
Result so far: 6611.14
If we subtract 312 from 320, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
80 divided by 78 is 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 6611.141
Subtracting 78 from 80 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 10:
When dividing 20 by 78, we get 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 6611.141
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 11:
78 goes into 200 2 times with a remainder of 44.
Write down 2 as next digit of the result. 
Result so far: 6611.14102
Subtracting 156 from 200 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 12:
440 divided by 78 is 5 with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 6611.141025
The remainder is 50 after subtracting 390 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 13:
If we divide 500 by 78, we get 6 and a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 6611.1410256
Subtract 468 from 500 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 14:
320 divided by 78 is 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 6611.14102564
Subtracting 312 from 320 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 6611.14102564 with a remaining 8e-09.
