We look at the division of 78440020 by 6 
Let's see how many times 6 fits into 78440020.

Advancing to step 1:
If we divide 7 by 6, we get 1 and a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 6 away from 7, we end up with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 6

On to step 2:
The number 6 fits into 18 3 times, leaving a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 13.0
The remainder is 0 after subtracting 18 from 18.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 6

Step 3:
If we divide 4 by 6, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 130.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 6

Moving on to step 4:
6 can be fit into 44 7 times, resulting in a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 1307.0
Subtract 42 from 44 to get 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 6

Moving on to step 5:
20 divided by 6 is 3 with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 13073.0
Subtracting 18 from 20 leaves us with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 6

Going ahead to step 6:
6 goes into 20 3 times with a remainder of 2.
The next digit of our result is 3. 
Result so far: 130733.0
Subtracting 18 from 20 leaves us with 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 6

Moving on to step 7:
6 goes into 22 3 times with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 1307333.0
If we take 18 away from 22, we end up with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 6

Moving on to step 8:
When dividing 40 by 6, we get 6 with a remainder of 4.
The next digit of our result is 6. 
Result so far: 13073336.0
Subtract 36 from 40 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
When dividing 40 by 6, we get 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 13073336.6
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 10:
6 can be fit into 40 6 times, resulting in a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 13073336.66
Deduct 36 from 40 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

In conclusion, the division gives 13073336.66 with a balance of 0.004.
