We look at the division of 547639 by 80 
We want to figure out the number of times 547639 can be divided by 80.

Advancing to step 1:
When dividing 5 by 80, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 80

Let's proceed to step 2:
When dividing 54 by 80, we get 0 with a remainder of 54.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 54, we end up with 54.
Bring next digit (7) of the dividend behind the 54 and repeat the process: 547 / 80

Let's proceed to step 3:
The number 80 fits into 547 6 times, leaving a remainder of 67.
The next digit of our result is 6. 
Result so far: 6.0
If we subtract 480 from 547, we get 67.
Fetch the next digit (6) from the dividend, attach it to 67 and continue: 676 / 80

Step 4:
When dividing 676 by 80, we get 8 with a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 68.0
Subtract 640 from 676 to get 36.
Append the next digit (3) from the dividend to 36 and continue with: 363 / 80

Step 5:
When dividing 363 by 80, we get 4 with a remainder of 43.
Record the quotient 4 as the next digit in the result. 
Result so far: 684.0
Subtract 320 from 363 to get 43.
Take the next digit (9) from the dividend and append it to 43, then repeat: 439 / 80

Step 6:
439 divided by 80 is 5 with a remainder of 39.
Put 5 as the next digit of the answer. 
Result so far: 6845.0
The remainder is 39 after subtracting 400 from 439.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 7:
80 can be fit into 390 4 times, resulting in a remainder of 70.
The number 4 becomes the next digit in our result. 
Result so far: 6845.4
If we take 320 away from 390, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 8:
80 can be fit into 700 8 times, resulting in a remainder of 60.
Write down 8 as next digit of the result. 
Result so far: 6845.48
If we take 640 away from 700, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 9:
80 can be fit into 600 7 times, resulting in a remainder of 40.
Put 7 as the next digit of the answer. 
Result so far: 6845.487
The remainder is 40 after subtracting 560 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 10:
400 divided by 80 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 6845.4875
Deduct 400 from 400 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 11:
The number 80 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 6845.4875
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 12:
0 divided by 80 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 6845.4875
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 6845.4875, with a leftover of 0.0.
