We look at the division of 507930 by 78 
We want to figure out the number of times 507930 can be divided by 78.

Let's proceed to step 1:
The number 78 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 78

Going ahead to step 2:
78 can be fit into 50 0 times, resulting in a remainder of 50.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 50 and we're left with 50.
Bring next digit (7) of the dividend behind the 50 and repeat the process: 507 / 78

Going ahead to step 3:
507 divided by 78 is 6 with a remainder of 39.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtracting 468 from 507 leaves us with 39.
Grab the next digit (9) from the dividend, add it to 39, then carry on: 399 / 78

Let's proceed to step 4:
If we divide 399 by 78, we get 5 and a remainder of 9.
The next digit of our result is 5. 
Result so far: 65.0
Deduct 390 from 399 and we're left with 9.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 78

On to step 5:
78 goes into 93 1 times with a remainder of 15.
The next digit of our result is 1. 
Result so far: 651.0
The remainder is 15 after subtracting 78 from 93.
Append the next digit (0) from the dividend to 15 and continue with: 150 / 78

Going ahead to step 6:
When dividing 150 by 78, we get 1 with a remainder of 72.
Record the quotient 1 as the next digit in the result. 
Result so far: 6511.0
The remainder is 72 after subtracting 78 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 7:
78 goes into 720 9 times with a remainder of 18.
Write down 9 as next digit of the result. 
Result so far: 6511.9
Subtract 702 from 720 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 8:
If we divide 180 by 78, we get 2 and a remainder of 24.
The next digit of our result is 2. 
Result so far: 6511.92
Subtracting 156 from 180 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 9:
The number 78 fits into 240 3 times, leaving a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 6511.923
Deduct 234 from 240 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 10:
The number 78 fits into 60 0 times, leaving a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 6511.923
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 11:
78 can be fit into 600 7 times, resulting in a remainder of 54.
Record the quotient 7 as the next digit in the result. 
Result so far: 6511.92307
Deduct 546 from 600 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 12:
78 can be fit into 540 6 times, resulting in a remainder of 72.
Use 6 as the next digit of our solution. 
Result so far: 6511.923076
Deduct 468 from 540 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 13:
The number 78 fits into 720 9 times, leaving a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 6511.9230769
The remainder is 18 after subtracting 702 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 14:
When dividing 180 by 78, we get 2 with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 6511.92307692
If we take 156 away from 180, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The quotient of the division is 6511.92307692, and the remainder is 2.4e-08.
