Let's divide 542170 by 80
Our goal is to divide 542170 by 80.

Advancing to step 1:
5 divided by 80 is 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.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 80

Step 2:
The number 80 fits into 54 0 times, leaving a remainder of 54.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 54 after subtracting 0 from 54.
Bring next digit (2) of the dividend behind the 54 and repeat the process: 542 / 80

Step 3:
80 can be fit into 542 6 times, resulting in a remainder of 62.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 480 from 542 and we're left with 62.
Fetch the next digit (1) from the dividend, attach it to 62 and continue: 621 / 80

On to step 4:
If we divide 621 by 80, we get 7 and a remainder of 61.
The number 7 becomes the next digit in our result. 
Result so far: 67.0
The remainder is 61 after subtracting 560 from 621.
Bring next digit (7) of the dividend behind the 61 and repeat the process: 617 / 80

Moving on to step 5:
When dividing 617 by 80, we get 7 with a remainder of 57.
The next digit of our result is 7. 
Result so far: 677.0
Subtracting 560 from 617 leaves us with 57.
Fetch the next digit (0) from the dividend, attach it to 57 and continue: 570 / 80

Advancing to step 6:
80 can be fit into 570 7 times, resulting in a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 6777.0
If we take 560 away from 570, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 7:
If we divide 100 by 80, we get 1 and a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 6777.1
Deduct 80 from 100 and we're left 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.

Going ahead to step 8:
80 goes into 200 2 times with a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 6777.12
Deduct 160 from 200 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 9:
The number 80 fits into 400 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 6777.125
Subtract 400 from 400 to 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 10:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 6777.125
If we take 0 away from 0, we end up 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.
Record the quotient 0 as the next digit in the result. 
Result so far: 6777.125
Subtracting 0 from 0 leaves us 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.

Our division results in 6777.125 with a remaining 0.0.
