664053 ÷ 78 
Let's see how many times 78 fits into 664053.

Let's proceed to step 1:
6 divided by 78 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 78

Step 2:
78 goes into 66 0 times with a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Fetch the next digit (4) from the dividend, attach it to 66 and continue: 664 / 78

Moving on to step 3:
The number 78 fits into 664 8 times, leaving a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 624 from 664 leaves us with 40.
Append the next digit (0) from the dividend to 40 and continue with: 400 / 78

Moving on to step 4:
When dividing 400 by 78, we get 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 85.0
The remainder is 10 after subtracting 390 from 400.
Bring next digit (5) of the dividend behind the 10 and repeat the process: 105 / 78

Let's proceed to step 5:
The number 78 fits into 105 1 times, leaving a remainder of 27.
Record the quotient 1 as the next digit in the result. 
Result so far: 851.0
Subtracting 78 from 105 leaves us with 27.
Fetch the next digit (3) from the dividend, attach it to 27 and continue: 273 / 78

Let's proceed to step 6:
When dividing 273 by 78, we get 3 with a remainder of 39.
Put 3 as the next digit of the answer. 
Result so far: 8513.0
Subtract 234 from 273 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 7:
When dividing 390 by 78, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 8513.5
If we take 390 away from 390, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
The number 78 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 8513.5
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
78 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 8513.5
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 8513.5 and a remainder of 0.0.
