665595 ÷ 78 
We want to figure out the number of times 665595 can be divided by 78.

Let's proceed to step 1:
6 divided by 78 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 78

Let's proceed to step 2:
78 can be fit into 66 0 times, resulting in a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Bring next digit (5) of the dividend behind the 66 and repeat the process: 665 / 78

Advancing to step 3:
665 divided by 78 is 8 with a remainder of 41.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 624 from 665 to get 41.
Include the next digit (5) from the dividend after 41, then repeat: 415 / 78

Advancing to step 4:
If we divide 415 by 78, we get 5 and a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 85.0
If we take 390 away from 415, we end up with 25.
Bring next digit (9) of the dividend behind the 25 and repeat the process: 259 / 78

On to step 5:
The number 78 fits into 259 3 times, leaving a remainder of 25.
Put 3 as the next digit of the answer. 
Result so far: 853.0
Deduct 234 from 259 and we're left with 25.
Include the next digit (5) from the dividend after 25, then repeat: 255 / 78

Let's proceed to step 6:
255 divided by 78 is 3 with a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 8533.0
The remainder is 21 after subtracting 234 from 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 7:
The number 78 fits into 210 2 times, leaving a remainder of 54.
The next digit of our result is 2. 
Result so far: 8533.2
Subtracting 156 from 210 leaves us 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.

Advancing to step 8:
The number 78 fits into 540 6 times, leaving a remainder of 72.
The next digit of our result is 6. 
Result so far: 8533.26
Subtract 468 from 540 to 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.

Let's proceed to step 9:
78 goes into 720 9 times with a remainder of 18.
The next digit of our result is 9. 
Result so far: 8533.269
If we take 702 away from 720, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 10:
78 can be fit into 180 2 times, resulting in a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 8533.2692
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.

Advancing to step 11:
240 divided by 78 is 3 with a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 8533.26923
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.

Advancing to step 12:
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: 8533.26923
If we subtract 0 from 60, we 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 13:
600 divided by 78 is 7 with a remainder of 54.
Record the quotient 7 as the next digit in the result. 
Result so far: 8533.2692307
If we subtract 546 from 600, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 14:
540 divided by 78 is 6 with a remainder of 72.
Write down 6 as next digit of the result. 
Result so far: 8533.26923076
Subtracting 468 from 540 leaves us 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.

Our division results in 8533.26923076 with a remaining 7.2e-08.
