63559 ÷ 80 
We want to figure out the number of times 63559 can be divided by 80.

Step 1:
80 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 80

On to step 2:
When dividing 63 by 80, we get 0 with a remainder of 63.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 63, we get 63.
Append the next digit (5) from the dividend to 63 and continue with: 635 / 80

Going ahead to step 3:
The number 80 fits into 635 7 times, leaving a remainder of 75.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we subtract 560 from 635, we get 75.
Grab the next digit (5) from the dividend, add it to 75, then carry on: 755 / 80

Let's proceed to step 4:
The number 80 fits into 755 9 times, leaving a remainder of 35.
Record the quotient 9 as the next digit in the result. 
Result so far: 79.0
Subtracting 720 from 755 leaves us with 35.
Fetch the next digit (9) from the dividend, attach it to 35 and continue: 359 / 80

Let's proceed to step 5:
359 divided by 80 is 4 with a remainder of 39.
Write down 4 as next digit of the result. 
Result so far: 794.0
If we subtract 320 from 359, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 6:
80 can be fit into 390 4 times, resulting in a remainder of 70.
Put 4 as the next digit of the answer. 
Result so far: 794.4
Subtract 320 from 390 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 7:
80 can be fit into 700 8 times, resulting in a remainder of 60.
Put 8 as the next digit of the answer. 
Result so far: 794.48
Subtracting 640 from 700 leaves us 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.

Step 8:
The number 80 fits into 600 7 times, leaving a remainder of 40.
Write down 7 as next digit of the result. 
Result so far: 794.487
If we take 560 away from 600, we end up 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.

Let's proceed to step 9:
400 divided by 80 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 794.4875
Subtracting 400 from 400 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.

On to step 10:
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: 794.4875
Subtract 0 from 0 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.

Advancing to step 11:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 794.4875
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.

The final outcome is 794.4875, with a leftover of 0.0.
