507805 divided by 78 
We want to divide 507805 by 78.

On to step 1:
If we divide 5 by 78, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 78

Moving on to step 2:
50 divided by 78 is 0 with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 50, we end up with 50.
Fetch the next digit (7) from the dividend, attach it to 50 and continue: 507 / 78

Step 3:
The number 78 fits into 507 6 times, leaving a remainder of 39.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we take 468 away from 507, we end up with 39.
Bring next digit (8) of the dividend behind the 39 and repeat the process: 398 / 78

Step 4:
398 divided by 78 is 5 with a remainder of 8.
Record the quotient 5 as the next digit in the result. 
Result so far: 65.0
Subtract 390 from 398 to get 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 78

Moving on to step 5:
If we divide 80 by 78, we get 1 and a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 651.0
If we subtract 78 from 80, we get 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 78

Moving on to step 6:
The number 78 fits into 25 0 times, leaving a remainder of 25.
The next digit of our result is 0. 
Result so far: 6510.0
Subtracting 0 from 25 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.

Moving on to step 7:
78 goes into 250 3 times with a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 6510.3
Deduct 234 from 250 and we're left 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.

Let's proceed to step 8:
160 divided by 78 is 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 6510.32
The remainder is 4 after subtracting 156 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
40 divided by 78 is 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 6510.32
If we subtract 0 from 40, we 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.

Step 10:
When dividing 400 by 78, we get 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 6510.3205
Deduct 390 from 400 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 11:
If we divide 100 by 78, we get 1 and a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 6510.32051
Subtracting 78 from 100 leaves us 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 12:
The number 78 fits into 220 2 times, leaving a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 6510.320512
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.

Advancing to step 13:
If we divide 640 by 78, we get 8 and a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 6510.3205128
Subtracting 624 from 640 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.

Step 14:
When dividing 160 by 78, we get 2 with a remainder of 4.
The next digit of our result is 2. 
Result so far: 6510.32051282
Subtracting 156 from 160 leaves us 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.

The final outcome is 6510.32051282, with a leftover of 4e-09.
