We divide 507993 by 78
We want to figure out the number of times 507993 can be divided by 78.

On to step 1:
78 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 78

Moving on to step 2:
78 can be fit into 50 0 times, resulting in a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 50 to get 50.
Bring next digit (7) of the dividend behind the 50 and repeat the process: 507 / 78

Step 3:
78 can be fit into 507 6 times, resulting in a remainder of 39.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtract 468 from 507 to get 39.
Append the next digit (9) from the dividend to 39 and continue with: 399 / 78

Advancing to step 4:
78 goes into 399 5 times with a remainder of 9.
Write down 5 as next digit of the result. 
Result so far: 65.0
Deduct 390 from 399 and we're left with 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 78

Going ahead to step 5:
The number 78 fits into 99 1 times, leaving a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 651.0
Subtract 78 from 99 to get 21.
Bring next digit (3) of the dividend behind the 21 and repeat the process: 213 / 78

Step 6:
The number 78 fits into 213 2 times, leaving a remainder of 57.
Put 2 as the next digit of the answer. 
Result so far: 6512.0
The remainder is 57 after subtracting 156 from 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 7:
The number 78 fits into 570 7 times, leaving a remainder of 24.
Record the quotient 7 as the next digit in the result. 
Result so far: 6512.7
Subtracting 546 from 570 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 8:
78 can be fit into 240 3 times, resulting in a remainder of 6.
The next digit of our result is 3. 
Result so far: 6512.73
If we take 234 away from 240, we end up 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.

Let's proceed to step 9:
If we divide 60 by 78, we get 0 and a remainder of 60.
The next digit of our result is 0. 
Result so far: 6512.73
If we take 0 away from 60, we end up with 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 10:
600 divided by 78 is 7 with a remainder of 54.
Use 7 as the next digit of our solution. 
Result so far: 6512.7307
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.

Moving on to step 11:
78 can be fit into 540 6 times, resulting in a remainder of 72.
Record the quotient 6 as the next digit in the result. 
Result so far: 6512.73076
If we subtract 468 from 540, we get 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 12:
720 divided by 78 is 9 with a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 6512.730769
If we subtract 702 from 720, we 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 13:
If we divide 180 by 78, we get 2 and a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 6512.7307692
Deduct 156 from 180 and we're left 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.

Moving on to step 14:
78 can be fit into 240 3 times, resulting in a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 6512.73076923
If we subtract 234 from 240, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

In conclusion, the division gives 6512.73076923 with a balance of 6e-09.
