We're dividing 21083 by 80 
Our goal is to divide 21083 by 80.

Advancing to step 1:
2 divided by 80 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 80

Advancing to step 2:
80 goes into 21 0 times with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Append the next digit (0) from the dividend to 21 and continue with: 210 / 80

Advancing to step 3:
If we divide 210 by 80, we get 2 and a remainder of 50.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 50 after subtracting 160 from 210.
Take the next digit (8) from the dividend and append it to 50, then repeat: 508 / 80

Moving on to step 4:
80 goes into 508 6 times with a remainder of 28.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
Deduct 480 from 508 and we're left with 28.
Grab the next digit (3) from the dividend, add it to 28, then carry on: 283 / 80

Let's proceed to step 5:
283 divided by 80 is 3 with a remainder of 43.
Use 3 as the next digit of our solution. 
Result so far: 263.0
If we take 240 away from 283, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 6:
80 can be fit into 430 5 times, resulting in a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 263.5
Deduct 400 from 430 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.

Going ahead to step 7:
When dividing 300 by 80, we get 3 with a remainder of 60.
The number 3 becomes the next digit in our result. 
Result so far: 263.53
The remainder is 60 after subtracting 240 from 300.
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 8:
80 goes into 600 7 times with a remainder of 40.
Write down 7 as next digit of the result. 
Result so far: 263.537
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.

On to step 9:
400 divided by 80 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 263.5375
The remainder is 0 after subtracting 400 from 400.
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:
0 divided by 80 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 263.5375
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.

Moving on to step 11:
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: 263.5375
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 quotient of the division is 263.5375, and the remainder is 0.0.
