We look at the division of 505581 by 78 
We want to figure out the number of times 505581 can be divided by 78.

Moving on to step 1:
The number 78 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 78

Let's proceed to step 2:
50 divided by 78 is 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 50 after subtracting 0 from 50.
Bring next digit (5) of the dividend behind the 50 and repeat the process: 505 / 78

Let's proceed to step 3:
When dividing 505 by 78, we get 6 with a remainder of 37.
The next digit of our result is 6. 
Result so far: 6.0
If we subtract 468 from 505, we get 37.
Append the next digit (5) from the dividend to 37 and continue with: 375 / 78

Step 4:
The number 78 fits into 375 4 times, leaving a remainder of 63.
Use 4 as the next digit of our solution. 
Result so far: 64.0
Subtract 312 from 375 to get 63.
Bring next digit (8) of the dividend behind the 63 and repeat the process: 638 / 78

Advancing to step 5:
78 can be fit into 638 8 times, resulting in a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 648.0
If we subtract 624 from 638, we get 14.
Fetch the next digit (1) from the dividend, attach it to 14 and continue: 141 / 78

On to step 6:
141 divided by 78 is 1 with a remainder of 63.
Put 1 as the next digit of the answer. 
Result so far: 6481.0
If we subtract 78 from 141, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Advancing to step 7:
When dividing 630 by 78, we get 8 with a remainder of 6.
The next digit of our result is 8. 
Result so far: 6481.8
If we subtract 624 from 630, 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.

Step 8:
When dividing 60 by 78, we get 0 with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 6481.8
Subtract 0 from 60 to get 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 9:
When dividing 600 by 78, we get 7 with a remainder of 54.
Record the quotient 7 as the next digit in the result. 
Result so far: 6481.807
If we take 546 away from 600, we end up 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 10:
The number 78 fits into 540 6 times, leaving a remainder of 72.
Write down 6 as next digit of the result. 
Result so far: 6481.8076
If we take 468 away from 540, we end up 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.

Advancing to step 11:
78 can be fit into 720 9 times, resulting in a remainder of 18.
Put 9 as the next digit of the answer. 
Result so far: 6481.80769
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.

Step 12:
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: 6481.807692
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.

Step 13:
78 goes into 240 3 times with a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 6481.8076923
Subtract 234 from 240 to 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.

On to step 14:
60 divided by 78 is 0 with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 6481.8076923
Subtracting 0 from 60 leaves us 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.

Our division results in 6481.8076923 with a remaining 6e-08.
