We look at the division of 668072 by 78 
We're looking to find how many times 78 goes into 668072.

Let's proceed to step 1:
The number 78 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 78

Let's proceed to step 2:
When dividing 66 by 78, we get 0 with a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Grab the next digit (8) from the dividend, add it to 66, then carry on: 668 / 78

On to step 3:
The number 78 fits into 668 8 times, leaving a remainder of 44.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 624 from 668 to get 44.
Take the next digit (0) from the dividend and append it to 44, then repeat: 440 / 78

Let's proceed to step 4:
If we divide 440 by 78, we get 5 and a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 85.0
If we take 390 away from 440, we end up with 50.
Include the next digit (7) from the dividend after 50, then repeat: 507 / 78

Let's proceed to step 5:
The number 78 fits into 507 6 times, leaving a remainder of 39.
The number 6 becomes the next digit in our result. 
Result so far: 856.0
Subtracting 468 from 507 leaves us with 39.
Include the next digit (2) from the dividend after 39, then repeat: 392 / 78

On to step 6:
If we divide 392 by 78, we get 5 and a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 8565.0
The remainder is 2 after subtracting 390 from 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
When dividing 20 by 78, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 8565.0
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
78 can be fit into 200 2 times, resulting in a remainder of 44.
The number 2 becomes the next digit in our result. 
Result so far: 8565.02
If we take 156 away from 200, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 9:
78 can be fit into 440 5 times, resulting in a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 8565.025
If we subtract 390 from 440, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 10:
500 divided by 78 is 6 with a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 8565.0256
Subtracting 468 from 500 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 11:
78 goes into 320 4 times with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 8565.02564
If we take 312 away from 320, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 12:
If we divide 80 by 78, we get 1 and a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 8565.025641
If we take 78 away from 80, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 13:
The number 78 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 8565.025641
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 14:
78 can be fit into 200 2 times, resulting in a remainder of 44.
The next digit of our result is 2. 
Result so far: 8565.02564102
If we take 156 away from 200, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The final outcome is 8565.02564102, with a leftover of 4.4e-08.
