Let's divide 66653 by 78
Let's see how many times 78 fits into 66653.

On to step 1:
78 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 78

Going ahead to step 2:
66 divided by 78 is 0 with a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Take the next digit (6) from the dividend and append it to 66, then repeat: 666 / 78

On to step 3:
The number 78 fits into 666 8 times, leaving a remainder of 42.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 624 away from 666, we end up with 42.
Include the next digit (5) from the dividend after 42, then repeat: 425 / 78

Going ahead to step 4:
The number 78 fits into 425 5 times, leaving a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 85.0
Subtracting 390 from 425 leaves us with 35.
Include the next digit (3) from the dividend after 35, then repeat: 353 / 78

Advancing to step 5:
353 divided by 78 is 4 with a remainder of 41.
The number 4 becomes the next digit in our result. 
Result so far: 854.0
Subtract 312 from 353 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 6:
When dividing 410 by 78, we get 5 with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 854.5
If we subtract 390 from 410, 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.

Going ahead to step 7:
78 goes into 200 2 times with a remainder of 44.
The number 2 becomes the next digit in our result. 
Result so far: 854.52
Subtract 156 from 200 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 8:
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: 854.525
If we take 390 away from 440, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 9:
78 goes into 500 6 times with a remainder of 32.
The next digit of our result is 6. 
Result so far: 854.5256
If we take 468 away from 500, we end up 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.

Going ahead to step 10:
The number 78 fits into 320 4 times, leaving a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 854.52564
Subtracting 312 from 320 leaves us 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.

Step 11:
When dividing 80 by 78, we get 1 with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 854.525641
The remainder is 2 after subtracting 78 from 80.
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 12:
The number 78 fits into 20 0 times, leaving a remainder of 20.
The next digit of our result is 0. 
Result so far: 854.525641
Subtract 0 from 20 to 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.

Going ahead to step 13:
If we divide 200 by 78, we get 2 and a remainder of 44.
Write down 2 as next digit of the result. 
Result so far: 854.52564102
Subtracting 156 from 200 leaves us 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 854.52564102, with a leftover of 4.4e-08.
