213559 divided by 80 
We're looking to find how many times 80 goes into 213559.

Advancing to step 1:
If we divide 2 by 80, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 80

Let's proceed to step 2:
80 can be fit into 21 0 times, resulting in a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Bring next digit (3) of the dividend behind the 21 and repeat the process: 213 / 80

Moving on to step 3:
80 can be fit into 213 2 times, resulting in a remainder of 53.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 160 from 213 leaves us with 53.
Take the next digit (5) from the dividend and append it to 53, then repeat: 535 / 80

Step 4:
If we divide 535 by 80, we get 6 and a remainder of 55.
Use 6 as the next digit of our solution. 
Result so far: 26.0
Subtracting 480 from 535 leaves us with 55.
Grab the next digit (5) from the dividend, add it to 55, then carry on: 555 / 80

Going ahead to step 5:
If we divide 555 by 80, we get 6 and a remainder of 75.
The number 6 becomes the next digit in our result. 
Result so far: 266.0
Subtract 480 from 555 to get 75.
Take the next digit (9) from the dividend and append it to 75, then repeat: 759 / 80

On to step 6:
80 can be fit into 759 9 times, resulting in a remainder of 39.
Use 9 as the next digit of our solution. 
Result so far: 2669.0
Subtract 720 from 759 to 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.

Moving on to step 7:
390 divided by 80 is 4 with a remainder of 70.
Write down 4 as next digit of the result. 
Result so far: 2669.4
Deduct 320 from 390 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 8:
When dividing 700 by 80, we get 8 with a remainder of 60.
The next digit of our result is 8. 
Result so far: 2669.48
Subtract 640 from 700 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 9:
When dividing 600 by 80, we get 7 with a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 2669.487
Subtracting 560 from 600 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:
The number 80 fits into 400 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 2669.4875
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.

Moving on to step 11:
80 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 2669.4875
If we subtract 0 from 0, 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.

Moving on to step 12:
80 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 2669.4875
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.

After the division, we end up with 2669.4875 and a remainder of 0.0.
