612909 divided by 80 
Our goal is to divide 612909 by 80.

Moving on to step 1:
6 divided by 80 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 80

Moving on to step 2:
When dividing 61 by 80, we get 0 with a remainder of 61.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 61 after subtracting 0 from 61.
Append the next digit (2) from the dividend to 61 and continue with: 612 / 80

Advancing to step 3:
If we divide 612 by 80, we get 7 and a remainder of 52.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 560 from 612, we get 52.
Take the next digit (9) from the dividend and append it to 52, then repeat: 529 / 80

Moving on to step 4:
80 can be fit into 529 6 times, resulting in a remainder of 49.
The next digit of our result is 6. 
Result so far: 76.0
Subtract 480 from 529 to get 49.
Take the next digit (0) from the dividend and append it to 49, then repeat: 490 / 80

Let's proceed to step 5:
80 goes into 490 6 times with a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 766.0
If we subtract 480 from 490, we get 10.
Append the next digit (9) from the dividend to 10 and continue with: 109 / 80

Moving on to step 6:
The number 80 fits into 109 1 times, leaving a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 7661.0
Subtracting 80 from 109 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 7:
80 can be fit into 290 3 times, resulting in a remainder of 50.
Record the quotient 3 as the next digit in the result. 
Result so far: 7661.3
Deduct 240 from 290 and we're left 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.

Moving on to step 8:
500 divided by 80 is 6 with a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 7661.36
If we subtract 480 from 500, we 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 9:
If we divide 200 by 80, we get 2 and a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 7661.362
Subtracting 160 from 200 leaves us 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.

Going ahead to step 10:
When dividing 400 by 80, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 7661.3625
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.

On to step 11:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 7661.3625
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.

Let's proceed to step 12:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 7661.3625
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.

Our division results in 7661.3625 with a remaining 0.0.
