We're dividing 78579 by 80 
We want to figure out the number of times 78579 can be divided by 80.

Moving on to step 1:
80 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 80

Going ahead to step 2:
78 divided by 80 is 0 with a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Include the next digit (5) from the dividend after 78, then repeat: 785 / 80

Going ahead to step 3:
When dividing 785 by 80, we get 9 with a remainder of 65.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtract 720 from 785 to get 65.
Grab the next digit (7) from the dividend, add it to 65, then carry on: 657 / 80

Going ahead to step 4:
80 goes into 657 8 times with a remainder of 17.
Record the quotient 8 as the next digit in the result. 
Result so far: 98.0
If we subtract 640 from 657, we get 17.
Fetch the next digit (9) from the dividend, attach it to 17 and continue: 179 / 80

Going ahead to step 5:
When dividing 179 by 80, we get 2 with a remainder of 19.
The next digit of our result is 2. 
Result so far: 982.0
If we subtract 160 from 179, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 6:
When dividing 190 by 80, we get 2 with a remainder of 30.
The next digit of our result is 2. 
Result so far: 982.2
The remainder is 30 after subtracting 160 from 190.
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 7:
300 divided by 80 is 3 with a remainder of 60.
Use 3 as the next digit of our solution. 
Result so far: 982.23
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.

Advancing to step 8:
80 can be fit into 600 7 times, resulting in a remainder of 40.
Write down 7 as next digit of the result. 
Result so far: 982.237
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.

Advancing to step 9:
When dividing 400 by 80, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 982.2375
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.

Step 10:
When dividing 0 by 80, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 982.2375
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.

On to step 11:
If we divide 0 by 80, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 982.2375
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 982.2375, with a leftover of 0.0.
