We look at the division of 663956 by 78 
We want to figure out the number of times 663956 can be divided by 78.

Let's proceed to step 1:
When dividing 6 by 78, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 78

Step 2:
If we divide 66 by 78, we get 0 and a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Fetch the next digit (3) from the dividend, attach it to 66 and continue: 663 / 78

Moving on to step 3:
78 goes into 663 8 times with a remainder of 39.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 624 from 663 leaves us with 39.
Append the next digit (9) from the dividend to 39 and continue with: 399 / 78

Moving on to step 4:
78 goes into 399 5 times with a remainder of 9.
Write down 5 as next digit of the result. 
Result so far: 85.0
If we subtract 390 from 399, we get 9.
Fetch the next digit (5) from the dividend, attach it to 9 and continue: 95 / 78

Let's proceed to step 5:
If we divide 95 by 78, we get 1 and a remainder of 17.
The next digit of our result is 1. 
Result so far: 851.0
If we subtract 78 from 95, we get 17.
Fetch the next digit (6) from the dividend, attach it to 17 and continue: 176 / 78

Going ahead to step 6:
176 divided by 78 is 2 with a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 8512.0
If we take 156 away from 176, we end up 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.

Step 7:
78 can be fit into 200 2 times, resulting in a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 8512.2
Deduct 156 from 200 and we're left 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.

Step 8:
78 goes into 440 5 times with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 8512.25
Subtracting 390 from 440 leaves us 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.

Advancing 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: 8512.256
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.

Advancing to step 10:
320 divided by 78 is 4 with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 8512.2564
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.

Going ahead to step 11:
78 can be fit into 80 1 times, resulting in a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 8512.25641
Subtract 78 from 80 to get 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 12:
The number 78 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 8512.25641
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.

Moving on to step 13:
200 divided by 78 is 2 with a remainder of 44.
Write down 2 as next digit of the result. 
Result so far: 8512.2564102
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.

Let's proceed to step 14:
When dividing 440 by 78, we get 5 with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 8512.25641025
Subtracting 390 from 440 leaves us 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.

Our division results in 8512.25641025 with a remaining 5e-08.
