We're dividing 21283 by 8 
We're looking to find how many times 8 goes into 21283.

On to step 1:
When dividing 2 by 8, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 8

On to step 2:
8 goes into 21 2 times with a remainder of 5.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 16 from 21, we get 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 8

Advancing to step 3:
The number 8 fits into 52 6 times, leaving a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 26.0
Subtracting 48 from 52 leaves us with 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 8

Advancing to step 4:
8 goes into 48 6 times with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 266.0
Subtracting 48 from 48 leaves us with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 8

Step 5:
When dividing 3 by 8, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 2660.0
Subtracting 0 from 3 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 6:
8 can be fit into 30 3 times, resulting in a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 2660.3
Deduct 24 from 30 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 7:
The number 8 fits into 60 7 times, leaving a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 2660.37
Subtract 56 from 60 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 8:
The number 8 fits into 40 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 2660.375
Subtracting 40 from 40 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 9:
If we divide 0 by 8, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 2660.375
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.

On to step 10:
The number 8 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 2660.375
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.

The quotient of the division is 2660.375, and the remainder is 0.0.
