We look at the division of 585379 by 80 
We want to divide 585379 by 80.

Step 1:
The number 80 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 80

Advancing to step 2:
The number 80 fits into 58 0 times, leaving a remainder of 58.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 58, we end up with 58.
Bring next digit (5) of the dividend behind the 58 and repeat the process: 585 / 80

On to step 3:
585 divided by 80 is 7 with a remainder of 25.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 25 after subtracting 560 from 585.
Bring next digit (3) of the dividend behind the 25 and repeat the process: 253 / 80

Let's proceed to step 4:
The number 80 fits into 253 3 times, leaving a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 73.0
Subtracting 240 from 253 leaves us with 13.
Grab the next digit (7) from the dividend, add it to 13, then carry on: 137 / 80

Advancing to step 5:
80 goes into 137 1 times with a remainder of 57.
Record the quotient 1 as the next digit in the result. 
Result so far: 731.0
If we subtract 80 from 137, we get 57.
Grab the next digit (9) from the dividend, add it to 57, then carry on: 579 / 80

On to step 6:
If we divide 579 by 80, we get 7 and a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 7317.0
If we take 560 away from 579, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 7:
80 can be fit into 190 2 times, resulting in a remainder of 30.
Record the quotient 2 as the next digit in the result. 
Result so far: 7317.2
Deduct 160 from 190 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
If we divide 300 by 80, we get 3 and a remainder of 60.
Put 3 as the next digit of the answer. 
Result so far: 7317.23
If we take 240 away from 300, 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:
When dividing 600 by 80, we get 7 with a remainder of 40.
The next digit of our result is 7. 
Result so far: 7317.237
Deduct 560 from 600 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.

Step 10:
The number 80 fits into 400 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 7317.2375
If we subtract 400 from 400, 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.

On to step 11:
If we divide 0 by 80, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 7317.2375
Deduct 0 from 0 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 12:
80 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 7317.2375
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.

After the division, we end up with 7317.2375 and a remainder of 0.0.
