We look at the division of 644010 by 78 
We want to figure out the number of times 644010 can be divided by 78.

Let's proceed to step 1:
78 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 78

Moving on to step 2:
78 can be fit into 64 0 times, resulting in a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Bring next digit (4) of the dividend behind the 64 and repeat the process: 644 / 78

Step 3:
If we divide 644 by 78, we get 8 and a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 624 from 644, we get 20.
Grab the next digit (0) from the dividend, add it to 20, then carry on: 200 / 78

Let's proceed to step 4:
The number 78 fits into 200 2 times, leaving a remainder of 44.
Use 2 as the next digit of our solution. 
Result so far: 82.0
Subtracting 156 from 200 leaves us with 44.
Grab the next digit (1) from the dividend, add it to 44, then carry on: 441 / 78

Going ahead to step 5:
78 can be fit into 441 5 times, resulting in a remainder of 51.
Use 5 as the next digit of our solution. 
Result so far: 825.0
Subtract 390 from 441 to get 51.
Append the next digit (0) from the dividend to 51 and continue with: 510 / 78

Let's proceed to step 6:
When dividing 510 by 78, we get 6 with a remainder of 42.
The number 6 becomes the next digit in our result. 
Result so far: 8256.0
The remainder is 42 after subtracting 468 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 7:
The number 78 fits into 420 5 times, leaving a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 8256.5
If we subtract 390 from 420, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
300 divided by 78 is 3 with a remainder of 66.
The number 3 becomes the next digit in our result. 
Result so far: 8256.53
Subtract 234 from 300 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 9:
If we divide 660 by 78, we get 8 and a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 8256.538
Subtract 624 from 660 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 10:
360 divided by 78 is 4 with a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 8256.5384
Deduct 312 from 360 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 11:
78 goes into 480 6 times with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 8256.53846
Subtract 468 from 480 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 12:
78 goes into 120 1 times with a remainder of 42.
Use 1 as the next digit of our solution. 
Result so far: 8256.538461
The remainder is 42 after subtracting 78 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 13:
The number 78 fits into 420 5 times, leaving a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 8256.5384615
Deduct 390 from 420 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 14:
When dividing 300 by 78, we get 3 with a remainder of 66.
Use 3 as the next digit of our solution. 
Result so far: 8256.53846153
Deduct 234 from 300 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

The quotient of the division is 8256.53846153, and the remainder is 6.6e-08.
