We're dividing 660603 by 78 
Let's see how many times 78 fits into 660603.

Let's proceed to step 1:
6 divided by 78 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 78

Step 2:
If we divide 66 by 78, we get 0 and a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Append the next digit (0) from the dividend to 66 and continue with: 660 / 78

On to step 3:
The number 78 fits into 660 8 times, leaving a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 624 away from 660, we end up with 36.
Take the next digit (6) from the dividend and append it to 36, then repeat: 366 / 78

Going ahead to step 4:
When dividing 366 by 78, we get 4 with a remainder of 54.
Use 4 as the next digit of our solution. 
Result so far: 84.0
Subtract 312 from 366 to get 54.
Fetch the next digit (0) from the dividend, attach it to 54 and continue: 540 / 78

Moving on to step 5:
78 goes into 540 6 times with a remainder of 72.
The next digit of our result is 6. 
Result so far: 846.0
Subtracting 468 from 540 leaves us with 72.
Grab the next digit (3) from the dividend, add it to 72, then carry on: 723 / 78

Advancing to step 6:
When dividing 723 by 78, we get 9 with a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 8469.0
If we take 702 away from 723, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 7:
210 divided by 78 is 2 with a remainder of 54.
Use 2 as the next digit of our solution. 
Result so far: 8469.2
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.

Moving on to step 8:
540 divided by 78 is 6 with a remainder of 72.
The next digit of our result is 6. 
Result so far: 8469.26
Deduct 468 from 540 and we're left 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.

Going ahead to step 9:
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: 8469.269
If we subtract 702 from 720, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 10:
180 divided by 78 is 2 with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 8469.2692
Subtract 156 from 180 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 11:
The number 78 fits into 240 3 times, leaving a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 8469.26923
If we subtract 234 from 240, 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.

Moving on to step 12:
78 can be fit into 60 0 times, resulting in a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 8469.26923
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.

Step 13:
78 can be fit into 600 7 times, resulting in a remainder of 54.
The number 7 becomes the next digit in our result. 
Result so far: 8469.2692307
Subtract 546 from 600 to 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.

Moving on to step 14:
78 goes into 540 6 times with a remainder of 72.
The next digit of our result is 6. 
Result so far: 8469.26923076
The remainder is 72 after subtracting 468 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The final outcome is 8469.26923076, with a leftover of 7.2e-08.
