We look at the division of 485780 by 78 
We want to divide 485780 by 78.

Step 1:
When dividing 4 by 78, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 78

Advancing to step 2:
The number 78 fits into 48 0 times, leaving a remainder of 48.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 48 after subtracting 0 from 48.
Bring next digit (5) of the dividend behind the 48 and repeat the process: 485 / 78

On to step 3:
485 divided by 78 is 6 with a remainder of 17.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 468 away from 485, we end up with 17.
Grab the next digit (7) from the dividend, add it to 17, then carry on: 177 / 78

Going ahead to step 4:
If we divide 177 by 78, we get 2 and a remainder of 21.
Put 2 as the next digit of the answer. 
Result so far: 62.0
If we take 156 away from 177, we end up with 21.
Fetch the next digit (8) from the dividend, attach it to 21 and continue: 218 / 78

Advancing to step 5:
78 goes into 218 2 times with a remainder of 62.
Put 2 as the next digit of the answer. 
Result so far: 622.0
Deduct 156 from 218 and we're left with 62.
Bring next digit (0) of the dividend behind the 62 and repeat the process: 620 / 78

Step 6:
The number 78 fits into 620 7 times, leaving a remainder of 74.
Record the quotient 7 as the next digit in the result. 
Result so far: 6227.0
Subtract 546 from 620 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 7:
The number 78 fits into 740 9 times, leaving a remainder of 38.
The next digit of our result is 9. 
Result so far: 6227.9
The remainder is 38 after subtracting 702 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 8:
If we divide 380 by 78, we get 4 and a remainder of 68.
The number 4 becomes the next digit in our result. 
Result so far: 6227.94
If we subtract 312 from 380, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 9:
78 can be fit into 680 8 times, resulting in a remainder of 56.
Write down 8 as next digit of the result. 
Result so far: 6227.948
If we take 624 away from 680, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 10:
The number 78 fits into 560 7 times, leaving a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 6227.9487
The remainder is 14 after subtracting 546 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 11:
The number 78 fits into 140 1 times, leaving a remainder of 62.
Put 1 as the next digit of the answer. 
Result so far: 6227.94871
Deduct 78 from 140 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 12:
620 divided by 78 is 7 with a remainder of 74.
Put 7 as the next digit of the answer. 
Result so far: 6227.948717
Subtracting 546 from 620 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 13:
When dividing 740 by 78, we get 9 with a remainder of 38.
Record the quotient 9 as the next digit in the result. 
Result so far: 6227.9487179
Subtract 702 from 740 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 14:
78 goes into 380 4 times with a remainder of 68.
The number 4 becomes the next digit in our result. 
Result so far: 6227.94871794
Deduct 312 from 380 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Our division results in 6227.94871794 with a remaining 6.8e-08.
